Methodology: This was a retrospective study focusing on patients with an eyelid wound, over a 10-year period from 2012 to 2021. We collected and analyzed the data using Excel. Results: The frequency of eyelid wounds was 0.1%. The average age of our patients was 19.38 years with a range of 1 and 62 years. The sex ratio was 3.7. Eighty-one percent of patients lived in Dakar. Fifty-seven percent (57%) of patients consulted less than 24 hours after the trauma and 7% of patients on D1. The circumstances were brawls (11%), domestic accidents (9%), road accidents (6%), and work accidents (6%). We noted 1 case of dog bite. Thirteen patients presented with post-traumatic decreased visual acuity. Involvement of the isolated upper eyelid was noted in 40% of cases and both eyelids in 15% of cases. Involvement of the lacrimal ducts was noted in 17% of cases, and that of the free edge in 21% of cases. Eyelid wounds were associated with eyeball damage in 21% of cases. Various associated lesions were observed. Ninety-one percent of patients received surgical treatment. Three cases of superinfections, 1 case of conjunctival granuloma and 1 case of phthysis of the eyeball with postoperative retinal detachment were noted. Conclusion: Eyelid sores are relatively common in our context. They require rapid surgical treatment in order to preserve the functional and aesthetic prognosis. .展开更多

Kaposi Sarcoma can affect the ocular surface and adnexa and can masquerade as other entities, delaying prompt diagnosis can lead to diagnostic wandering delaying treatment. Our aim is to describe a case of KS of the eyelid in an HIV seronegative patient. Case Presentation: A seventy-year-old man developed a bilateral growing tumoral reddish purple vascular mass on both the lower and upper eyelid involving rapidly for 6 months. Both feet and the two shanks show the presence of a brown-violet tumor-shaped formation. The patient was negative for HIV. Histology examination showed a nodular tumor-like mass with a fibro hemangioma-epitheliomatous. Polymerase chain reaction was positive for human herpes virus 8. Initial chemotherapy followed by surgery was proposed to the patient. Unfortunately, the patient rejected treatment and was lost to follow-up. Conclusion: This case reports the difficulty of managing KS in developing countries.展开更多

It is more frequently associated with Down’s syndrome and black babies. If diagnosed early and treated properly, the condition can be managed without surgery. We report a case of non syndromic congenital bilateral severe upper eyelid eversion in otherwise normal 3 days old neonate of African descent (Tanzanian), born by vaginal delivery. The case was conservatively managed by lubricants, antibiotics and eyelid patching. We report this case because from the best of our knowledge it has never been documented here at our hospital and Tanzania before.展开更多

The eyelids can be damaged during these traumas. The most frequent lesions are lacerations, the surgical treatment of which is generally simple. In some cases, there are complex traumas where there is a loss of tissue, which is difficult to treat. We report the case of a 26-year-old young man, farmer with no medical and surgical history, referred by the odontostomatology and maxillofacial surgery department for burns to the left hemi face by the exhaust pipe of his motorbike which occurred following a public road accident (AVP). Observation: A 26-year-old young man with no medical-surgical history, visual acuity was 5/10 with good mobility of the globe. In collaboration with the maxillofacial surgeon, a graft of the hemi face was performed using a flap from the inner side of the thigh first. In the second time we carried out a recovery by a flap which consisted in taking a supra-superciliary flap and suturing it at the level of the palpebral edges which, in spite of a fragile vitality of the tissues. Conclusion: The reconstruction of the eyelid is a real problem in our service because of the technical platform and the availability of consumables, which limits us in the choice of the operating technique.展开更多

Despite the increasing demand for AB and advancements in surgical techniques, creating an optimal upper eyelid crease remains difficult. This study aimed to determine whether removing the preaponeurotic fat pad (PAF) had any effect on the revision surgery rates following primary Asian blepharoplasty. Methods: A retrospective comparative analysis was conducted on patients who underwent primary AB between January 2016 and December 2020. Patients were divided into PAF removed and PAF not removed groups. The outcomes in the groups were compared by the frequency of revision surgery following primary AB using the chi-square test (p Results: The study included 480 patients, 442 (92%) female and 38 (8%) male, and the final outcome was evaluated after 6 months postoperatively. 412 (86%) patients were observed to have PAF pads intraoperatively, while 68 (14%) had minimal/no PAF pads. In total, 115 (24%) patients underwent revision surgery, of whom 31 (27%) had PAF removed, 66 (57%) had PAF not removed, and 18 (16%) had minimal/no PAF noted. When compared to the PAF not removed group, the PAF removed group showed a significantly lower frequency of revision surgery between the two groups of patients (p = 0.0001). Conclusion: In the final outcome, not removing the PAF in primary AB indicated a strong association with an increase in revision surgery. The removal of PAF in primary AB showed a better overall outcome and patient satisfaction.展开更多

METHODS: Three cases of ocular injuries are described in children aged 6 years, 3 years and 8 months, following accidental instillation of superglue in the eye. RESULTS: In the first case there was sticking of eyelashes in the medial 1/3 of eyelids in both eyes. In the second case sticking of eye lashes was present in the lateral 1/3 of eyelids in the left eye. In the third case, superglue was present on the right cheek, above the right ear and sticking of eyelids in medial 1/3 in right eye. The eyelids were separated by pulling the lid margins with fingers in the first case and later on superglue was removed by trimming the eyelashes; and by direct trimming the eyelashes in second and third cases. There was no injury to other structures of anterior segment in the first two cases. However, removal of the superglue on the cornea resulted in corneal abrasion in the third case which healed with medical treatment and patching of the right eye. CONCLUSION: Accidental instillation of superglue is possible because of the appearance of the tube like eye ointment tube. Immediate medical aid will prevent ocular morbidity.展开更多

METHODS: In this retrospective study, a total of 2228 cases of eyelid tumors with pathologic diagnoses were enrolled. The eyelid tumors were classified into three groups according to tumor origin: epidermal, adnexal and miscellaneous, including melanocytic, neural and vascular lesions. Inflammatory tumor-like lesions were excluded. The clinical characteristics of the eyelid tumors were analyzed, including age, gender and lesion location. RESULTS: Most eyelid tumors were epidermal in origin(1080, 48.5%), followed by miscellaneous(885, 39.7%) and adnexal tumors(263, 11.8%). Among all the tumors, 292(13.1%) were malignant lesions, 1910(85.7%) benign and 26(1.1%) premalignant lesions. Most malignant tumors originated from epidermal cells(60.0%), followed by adnexal cells(34.6%). The most common malignant tumors were basal cell carcinomas(56.5%) followed by sebaceous carcinoma(34.6%), squamous cell carcinomas(3.8%) and lymphoma/plasmocytoma(1.7%). The benign and premalignant eyelid lesions mostly originated from epidermal cells(46.4%) followed by miscellaneous cell sources(45.2%), including melanocytic nevus(33.8%), seborrheic keratosis(13.7%), squamous cell papilloma(13.0%) and epidermal cysts(11.5%). CONCLUSION: Eyelid tumors are mostly epithelial in origin. Benign tumors are significantly more common than malignant tumors with an obvious female predominance, and the most frequent malignant tumor are basal cell carcinoma, sebaceous carcinoma and squamous cell carcinomas. The tumor clinical features varied among the different subtypes.展开更多

"Release hypothesis" proposed an intrinsic masticatory oculo- motor neural circuit and this kind circuit, which, however, has been observed only in amphibian. On the other hand, congenital miswiring hypothesis has overwhelmed other interpretations. However, the same phenomenon visualized in MGS cases was unveiled in human subjects without any sign of congenital oculomotor disorder. To further study co-firing of the upper eyelid and jaw muscles, we applied non-invasive EMG recording of the upper eyelid and ipsilateral masseter muscle belly in nine healthy volunteers. LP activity was determined initially by looking upward and active retraction of upper eyelid with head fixed. Then, dual channel inputs from upper eyelid and masseter muscle was recorded during tooth occlusion motivated by isometric masseter muscle contraction without jaw and face moving. The EMG recorded from upper eyelid when the subjects retracted eyelid with head fixed exhibited the same pattern as that collected during tooth occlusion, but the pattern was completely different from EMG of active eye closure. This reflects tooth occlusion evoked LP activity. Then, simultaneous co-firing of the LP and masseter muscle was recorded simultaneously during tooth occlusion without jaw movement. Finally, the aforemen- tioned co-firing was recorded when the subjects conducted rhythmic occlusion and synchronous EMG from both muscles was acquired. In conclusions, humans may also have an intrinsic masticatory oculomotor circuit and release hypothesis may apply, at least, to some cases of MGS.展开更多

The documents of 97 patients(126 eyes) were reviewed. The patients were treated with subconjunctival triamcinolone acetonide injections monthly and evaluated pre-and post-treatment by taking measurements of the upper margin reflex distance(MRD1, the distance between the upper-lid margin and the pupil center), lid aperture, lagophthalmos and proptosis. The patients were divided into the cured group, the improved group and the ineffective group based on the final treatment effectiveness. The improved group and the ineffective group were combined into non-cured group.RESULTS: The follow-up time was 23.45±14.86 mo. Of the patients, 63(64.9%) were assigned to the cured group, 22(22.7%) in the improved group, 12(12.4%) in the ineffective group. Injection times for cured group was 4.66±1.74, and for non-cured group was 5.17±2.08(P≤0.05). The MRD1 was significantly reduced between baseline and 1 mo after the initiation of treatment in the cured and improved groups(P〈0.001). The values did not change significantly after 4 mo for the improved group, while they continued to decrease in the cured group. In the ineffective group, the MRD1 did not significantly change after treatment. A statistically significant difference was observed between the baseline and post-treatment values of the mean muscle thickness(2.95±0.99 mm vs 2.04±0.63 mm, P〈0.05) and surface area(27.27±10.5 mm2 vs 18.3±7.04 mm2,P〈0.05) of the levator superioris with magnetic resonance imaging examination. Twelve patients(12.4%) relapsed after treatment and required additional subconjunctival injections. The main side effects included menstrual cycle disturbances(32%) and elevations of intra-ocular pressure(18.6%). CONCLUSION: A repeated subconjunctival injection of triamcinolone is an effective and relatively safe treatment for upper lid retraction due to thyroid-associated ophthalmopathy. This is related to the anti-inflammation effect of the medicine and the levator thickness can become thinner. Patients must be monitored regularly for recurrences and side effects.展开更多

文摘Essential Subtleties on the Silver Sea(《银海精微》)is a well-known ophthalmology work of traditional Chinese medicine(TCM).There are many discourses on eyelids diseases.This paper analyzed the classification of related diseases and their treatment methods and intends to sort out the pathogenesis of eyelids diseases related to the spleen and stomach function in TCM,thus inspiring new treatment ideas and guiding clinical treatment.Through the sorting out,it is found that the eyelids diseases are closely related to the function of the spleen and stomach such as the Qi(气)and blood generation and transformation,the blood circulation,and the Yin(阴)-Yang(阳)harmony.The corresponding treatments are various,including expelling the pathogen,moving Qi(气)and invigorating blood,warming and activating the spleen Yang(阳).
文摘·AIM:To characterize the phenylephrine test in aponeurotic and congenital eyelid ptosis,to determine the appropriate timing of the phenylephrine test,and to assess the responses of the upper and lower eyelids.·METHODS:This was a retrospective analysis of 140 eyes of 87 patients(mean age 52.29±16.45 y;22 males,65 females)with upper eyelid ptosis.Totally 88.6%had aponeurotic and 11.4%had congenital ptosis.For the evaluation of the responses of the upper and lower eyelids to topical 2.5%phenylephrine,the scleral show height,the marginal reflex distance(MRD)between the inferior margin of the upper eyelid and pupillary light reflex(MRD1),and between the central portion of the lower eyelid and pupillary light reflex(MRD2)were measured at the 2^(nd),5^(th),and15^(th)minutes.The changes of MRD1 and MRD2 with time(ΔMRD1 andΔMRD2)were evaluated.·RESULTS:The mean MRD1,MRD2.and scleral show heights increased within 5 min after testing,remaining largely stable between the 5^(th)-15^(th)minutes.The percentage of eyes with a greater response in MRD1 increased with increased severity of ptosis(P<0.05).Eyes with aponeurotic ptosis were more responsive to phenylephrine testing than congenital ptosis.The mild ptosis group had lower scleral show measurements and higherΔMRD2 values.TheΔMRD1 andΔMRD2 values were poorly correlated in all measurement times.·CONCLUSION:Performing the phenylephrine test 5 min after instilling the reagent is adequate to assess the maximum response of the upper and lower eyelids.The upper and lower eyelid responses in phenylephrine testing are poorly correlated.However,theΔMRD2 is related with baseline scleral show degree that may be a postoperative predictive factor.Further studies are necessary to determine the relationship between the responses of the lower eyelids to phenylephrine testing.
文摘Objective:To explore the clinical efficacy of plastic surgery of asymmetric double eyelid.Methods:The clinical data of 70 patients with asymmetrical double eyelid who underwent plastic surgery in our hospital from April 2018 to December 2019 were retrospectively analyzed.The patients were divided into different groups based on different plastic surgery procedures.The control group(n=35 cases)were the patients who underwent double eyelid incision method,and the patients who used embedding double eyelid method were included in the observation group(n=35 cases).The operation time,intraoperative blood loss,incision size,healing time of incision,satisfaction of p1astic surgery and occurrence of complications were compared between the two groups.Results:The operation time and incision healing time of the observation group were shorter than those of the control group.The intraoperative blood 1oss and incision were less than those of the control group,and the satisfaction was higher than that of the control group.The difference was statistically significant(P<0.05).The incidence of complications in the observation group was slightly lower than the control group,but the difference was not statistically significant(P>0.05).Conclusion:For asymmetric double eyelid,it should undergo embedding double eyelid plastic surgery,because the operation time and incision healing time are shorter.And intraoperative blood 1oss and incision size are smal1er,which can improve patient satisfaction and reduce the incidence of complications.
文摘Background:Upper eyelid retraction is a challenging complication of cosmetic upper eyelid blepharoplasty.To avoid extra trauma,we developed a new technique for correcting iatrogenic upper eyelid retraction by postmigrating a compound flap of the orbicularis muscle and fascia(OFC)on the anterior surface of the tarsal plate.This method extends the aponeurosis of the levator palpebrae superioris muscle(LPS),which can achieve a good correction for post-blepharoplasty retraction.Methods:We collected data from 15 patients with mild to moderate iatrogenic upper eyelid retraction who were treated at our hospital between February 2017 and December 2019.The OFC was used to replace the missing part of the LPS,and post-migration of the LPS and fixation of the OFC to the tarsal margin were conducted.Postoperative outcome measurements included postoperative binocular symmetry,double eyelid smoothness,eyelid fullness,margin reflex distance(MRD1),degree of eyelid closure,and exposure keratitis.The patients were followed-up at seven days,one month,and six months postoperatively.Results:One patient with moderate eyelid retraction showed undercorrection 6 months postoperatively,with the upper eyelid margin located at the upper edge of the pupil.The remaining patients had the upper eyelid margin stabilized at 1.0–2.0 mm below the upper corneal margin.Other observational indicators were satisfactory,including binocular symmetry,double eyelid fluency,and eyelid fullness.During the follow-up,no exposure keratitis was identified.The MRD1 indexes after the operation were significantly different(P<0.001)from those before the procedure.Conclusions:Extension and post-migration of the LPS using the orbicularis muscle and OFC structure can effectively correct mild iatrogenic eyelid retraction after ptosis with less damage and good postoperative eyelid morphology and closure function.
文摘Purpose: The aim is to show epidemiological, clinical and etiological characteristics of palpebral wounds. Methodology: This was a retrospective study focusing on patients with an eyelid wound, over a 10-year period from 2012 to 2021. We collected and analyzed the data using Excel. Results: The frequency of eyelid wounds was 0.1%. The average age of our patients was 19.38 years with a range of 1 and 62 years. The sex ratio was 3.7. Eighty-one percent of patients lived in Dakar. Fifty-seven percent (57%) of patients consulted less than 24 hours after the trauma and 7% of patients on D1. The circumstances were brawls (11%), domestic accidents (9%), road accidents (6%), and work accidents (6%). We noted 1 case of dog bite. Thirteen patients presented with post-traumatic decreased visual acuity. Involvement of the isolated upper eyelid was noted in 40% of cases and both eyelids in 15% of cases. Involvement of the lacrimal ducts was noted in 17% of cases, and that of the free edge in 21% of cases. Eyelid wounds were associated with eyeball damage in 21% of cases. Various associated lesions were observed. Ninety-one percent of patients received surgical treatment. Three cases of superinfections, 1 case of conjunctival granuloma and 1 case of phthysis of the eyeball with postoperative retinal detachment were noted. Conclusion: Eyelid sores are relatively common in our context. They require rapid surgical treatment in order to preserve the functional and aesthetic prognosis. .
文摘Introduction: Kaposi sarcoma disease is a proliferative and multifocal disorder with dual components, vascular and fibroblastic cellular, cutaneous and visceral expression. Kaposi Sarcoma can affect the ocular surface and adnexa and can masquerade as other entities, delaying prompt diagnosis can lead to diagnostic wandering delaying treatment. Our aim is to describe a case of KS of the eyelid in an HIV seronegative patient. Case Presentation: A seventy-year-old man developed a bilateral growing tumoral reddish purple vascular mass on both the lower and upper eyelid involving rapidly for 6 months. Both feet and the two shanks show the presence of a brown-violet tumor-shaped formation. The patient was negative for HIV. Histology examination showed a nodular tumor-like mass with a fibro hemangioma-epitheliomatous. Polymerase chain reaction was positive for human herpes virus 8. Initial chemotherapy followed by surgery was proposed to the patient. Unfortunately, the patient rejected treatment and was lost to follow-up. Conclusion: This case reports the difficulty of managing KS in developing countries.
文摘Congenital eversion of the upper eyelids is a rare condition, the exact cause of which remains unknown. It is more frequently associated with Down’s syndrome and black babies. If diagnosed early and treated properly, the condition can be managed without surgery. We report a case of non syndromic congenital bilateral severe upper eyelid eversion in otherwise normal 3 days old neonate of African descent (Tanzanian), born by vaginal delivery. The case was conservatively managed by lubricants, antibiotics and eyelid patching. We report this case because from the best of our knowledge it has never been documented here at our hospital and Tanzania before.
文摘Ocular surface disease(OSD)can have a severe impact on patients as it can lead to visual impairment and persistent discomfort.Ocular surface reconstruction(OSR)is an approach to the management of ocular diseases that cause structural damage to the ocular surface.OSR encompasses both medical and surgical treatment options.In this review,we discuss the medical and surgical strategies used in OSR.Medical management often aims to treat tear insufficiency,inflammation,and keratinization.Surgical treatments may be employed for a variety of reasons,including failure of medical management.This may include improving the oculo-palpebral structures in order to improve lid positioning and tear film.Additional therapies focus on improving tear production,such as through salivary gland transplantation.In situations where the ocular surface is so severely damaged that there is loss of limbal stem cells,limbal stem cell transplant(LSCT)may be indicated.Other surgeries such as amniotic membrane transplant(AMT)and conjunctival flaps(CFs)can help promote corneal healing.Finally,in severe situations where the cornea is beyond salvage,corneal transplantation,such as a penetrating keratoplasty(PKP),can be considered.OSR often requires a combination of medical and surgical approaches targeted to each specific patient’s presentation in order to achieve optimal outcomes.
文摘The demand for procedures aiming to rejuvenate the upper third part of the face and the periocular region has increased in the past several years.Blepharoplasty is one of the most frequently performed procedures worldwide to date.Surgery is currently the first choice in order to achieve permanent and effective results;however,it is burdened by potential surgical complications feared by patients.There is an increasing trend in individuals to request less invasive,non-surgical,effective,and safe procedures for eyelid treatment.The aim of this minireview is to present a brief overview of non-surgical blepharoplasty techniques that have been reported in the literature in the past 10 years.Numerous modern techniques that provide a rejuvenation of the entire area have been described.Numerous less invasive methods have been proposed in the current literature and in modern-day routine clinical settings.Dermal fillers are a commonly chosen option for providing enhanced aesthetic results,especially considering that volume loss can be one of the main underlying causes of facial and periorbital aging.Deoxycholic acid use may be considered when the problem is represented by periorbital excess fat deposits.The simultaneous excess and loss of elasticity of the skin can be assessed with techniques such as lasers and plasma exeresis.Furthermore,techniques such as platelet-rich plasma injections and the insertion of twisted polydioxanone threads are emerging as viable methods to rejuvenate the periorbital region.

文摘The landscape of ophthalmology has obser ved monumental shifts with the advent of artificial intelligence(AI)technologies.This article is devoted to elaborating on the nuanced application of AI in the diagnostic realm of anterior segment eye diseases,an area ripe with potential yet complex in its imaging characteristics.Historically,AI’s entrenchment in ophthalmology was predominantly rooted in the posterior segment.However,the evolution of machine learning paradigms,particularly with the advent of deep learning methodologies,has reframed the focus.When combined with the exponential surge in available electronic image data pertaining to the anterior segment,AI’s role in diagnosing corneal,conjunctival,lens,and eyelid pathologies has been solidified and has emerged from the realm of theoretical to practical.In light of this transformative potential,collaborations between the Ophthalmic Imaging and Intelligent Medicine Subcommittee of the China Medical Education Association and the Ophthalmology Committee of the International Translational Medicine Association have been instrumental.These eminent bodies mobilized a consortium of experts to dissect and assimilate advancements from both national and international quarters.Their mandate was not limited to AI’s application in anterior segment pathologies like the cornea,conjunctiva,lens,and eyelids,but also ventured into deciphering the existing impediments and envisioning future trajectories.After iterative deliberations,the consensus synthesized herein serves as a touchstone,assisting ophthalmologists in optimally integrating AI into their diagnostic decisions and bolstering clinical research.Through this guideline,we aspire to offer a comprehensive framework,ensuring that clinical decisions are not merely informed but transformed by AI.By building upon existing literature yet maintaining the highest standards of originality,this document stands as a testament to both innovation and academic integrity,in line with the ethos of renowned journals such as Ophthalmology.
文摘In ophthalmological practice,eyelid reconstruction is often needed because of the presence of defects that arise after the excision of a tumor or after injuries.Various methods for reconstructing these defects have been previously described.However,it is important to understand the basic principles underlying these techniques and their advantages and disadvantages to ensure the choice of the optimal technique in a particular case.We have analyzed the recent literature on new methods or modifications of existing ones to provide a brief overview of the reconstructive methods of the century for comparison.We searched PubMed and CyberLeninka for articles on restoring eyelid defects reported in the literature over the past 10 years.Most techniques can be considered modified classical reconstruction methods.Postoperative complications included aesthetic defects,such as scarring of the upper or lower eyelid,trichiasis,entropion,and lagophthalmos.Surgeons continue to search for the best methods for complex reconstructive surgery to achieve good cosmetic and aesthetic outcomes.

文摘AIM:To describe the subcutaneous pedicled propeller flap technique for the microscopic reconstruction of eyelid defects and evaluate its outcomes.METHODS:The clinical data of 23 patients(23 eyes)who underwent microscopic reconstruction of eyelid defects with the subcutaneous pedicled propeller flap technique were retrospectively analyzed.All patients underwent eyelid tumor resection and one-stage microscopic reconstruction with the subcutaneous pedicled propeller flap for anterioror posterior-layer eyelid defects.The survival rate of the propeller flap,eyelid function and appearance,tumor recurrence rate,and patient satisfaction were evaluated after the surgery.RESULTS:The patients consisted of 12 men and 11 women,aged 31–82y(mean,58.9y).The longest followup time was 5y,and the shortest was 3mo.All the propeller flaps survived well.There was no significant difference in color and luster between the flap and adjacent tissues,and there was no dog ear phenomenon.No obvious scarring was observed.There were no obvious abnormalities of eyelid morphology or function,and no adverse complications such as exposure keratitis,entropion,ectropion,ptosis,and eyelid retraction.No tumor recurrence was found at the time of the last follow-up.All patients were satisfied with the surgical results.CONCLUSION:The subcutaneous pedicled propeller flap technique for the microscopic reconstruction of eyelid defects has satisfactor y outcomes in terms of eyelid function and esthetics,and merits clinical application.
文摘Background The abundance of closely packed vital structures in the periocular and palpebral regions makes resection and subsequent reconstructive interventions extremely difficult.Methods In this novel article,we described a method for closing lower eyelid defects after tumor excision using a skin-muscle flap from the upper eyelid along with the use of an adhesive diplene biodegradable membrane.The membrane was used for seamless fixation of the flap and to prevent the development of lower eyelid deformity.Results The case presented herein demonstrated that using diplene adhesive biodegradable membranes has excellent functional and aesthetic results.Conclusion Our findings suggest that an adhesive biodegradable diplene membrane can be used for the reconstruction of the lower eyelid to prevent the occurrence of retraction,for the surgical treatment of ectropion including recurrent cases,and for seamless fixation of flaps to wound surfaces in patients with a tendency to form keloids and hypertrophic scars.
文摘Introduction: Significant trauma to the periocular region can seriously damage ocular structures and their adnexa. The eyelids can be damaged during these traumas. The most frequent lesions are lacerations, the surgical treatment of which is generally simple. In some cases, there are complex traumas where there is a loss of tissue, which is difficult to treat. We report the case of a 26-year-old young man, farmer with no medical and surgical history, referred by the odontostomatology and maxillofacial surgery department for burns to the left hemi face by the exhaust pipe of his motorbike which occurred following a public road accident (AVP). Observation: A 26-year-old young man with no medical-surgical history, visual acuity was 5/10 with good mobility of the globe. In collaboration with the maxillofacial surgeon, a graft of the hemi face was performed using a flap from the inner side of the thigh first. In the second time we carried out a recovery by a flap which consisted in taking a supra-superciliary flap and suturing it at the level of the palpebral edges which, in spite of a fragile vitality of the tissues. Conclusion: The reconstruction of the eyelid is a real problem in our service because of the technical platform and the availability of consumables, which limits us in the choice of the operating technique.
文摘Background: Asian Blepharoplasty (AB) is one of the most commonly performed aesthetic procedures today. Despite the increasing demand for AB and advancements in surgical techniques, creating an optimal upper eyelid crease remains difficult. This study aimed to determine whether removing the preaponeurotic fat pad (PAF) had any effect on the revision surgery rates following primary Asian blepharoplasty. Methods: A retrospective comparative analysis was conducted on patients who underwent primary AB between January 2016 and December 2020. Patients were divided into PAF removed and PAF not removed groups. The outcomes in the groups were compared by the frequency of revision surgery following primary AB using the chi-square test (p Results: The study included 480 patients, 442 (92%) female and 38 (8%) male, and the final outcome was evaluated after 6 months postoperatively. 412 (86%) patients were observed to have PAF pads intraoperatively, while 68 (14%) had minimal/no PAF pads. In total, 115 (24%) patients underwent revision surgery, of whom 31 (27%) had PAF removed, 66 (57%) had PAF not removed, and 18 (16%) had minimal/no PAF noted. When compared to the PAF not removed group, the PAF removed group showed a significantly lower frequency of revision surgery between the two groups of patients (p = 0.0001). Conclusion: In the final outcome, not removing the PAF in primary AB indicated a strong association with an increase in revision surgery. The removal of PAF in primary AB showed a better overall outcome and patient satisfaction.
文摘AIM: To report various ocular lesions caused by accidental instillation of superglue. METHODS: Three cases of ocular injuries are described in children aged 6 years, 3 years and 8 months, following accidental instillation of superglue in the eye. RESULTS: In the first case there was sticking of eyelashes in the medial 1/3 of eyelids in both eyes. In the second case sticking of eye lashes was present in the lateral 1/3 of eyelids in the left eye. In the third case, superglue was present on the right cheek, above the right ear and sticking of eyelids in medial 1/3 in right eye. The eyelids were separated by pulling the lid margins with fingers in the first case and later on superglue was removed by trimming the eyelashes; and by direct trimming the eyelashes in second and third cases. There was no injury to other structures of anterior segment in the first two cases. However, removal of the superglue on the cornea resulted in corneal abrasion in the third case which healed with medical treatment and patching of the right eye. CONCLUSION: Accidental instillation of superglue is possible because of the appearance of the tube like eye ointment tube. Immediate medical aid will prevent ocular morbidity.
文摘AIM:To evaluate the functional and aesthetic outcomes of upper eyelid cicatricial entropion(UCE) correction using anterior lamellar recession(ALR) with addressing the associated conditions including dermatochalasis,brow ptosis,blepharoptosis,and lid retraction.METHODS:Chart review of patients with upper lid cicatricial entropion who had undergone ALR from 2013 to 2016 was reviewed.Success was defi ned as the lack of any lash in contact with the globe,no need for a second procedure,and acceptable cosmesis at the fi nal follow up.RESULTS:Sixty eight patients(97 eyelids) were operated by ALR with simultaneous correction of associated lid problems in each case when necessary.The mean followup time was 17.8 mo(range,6.0-24.0 mo).Concomitantly,levator tucking was performed in 19 eyelids(19.6%),upper lid retractor recession in 18 eyelids(18.6%),and internal browpexy in 31 eyelids(32.0%).In 95.8% of patients(95%CI:0.85-0.96),satisfactory functional and cosmetic outcome was achieved with a single surgical procedure.CONCLUSION:Based on the principles of lamellar recession and concurrently addressing the associated lid problems,this approach is an effective and safe treatment of UCE.
文摘AIM: To describe the histopathologic and clinical features of eyelid tumor cases from Tianjin Eye Hospital during 2002 to 2015. METHODS: In this retrospective study, a total of 2228 cases of eyelid tumors with pathologic diagnoses were enrolled. The eyelid tumors were classified into three groups according to tumor origin: epidermal, adnexal and miscellaneous, including melanocytic, neural and vascular lesions. Inflammatory tumor-like lesions were excluded. The clinical characteristics of the eyelid tumors were analyzed, including age, gender and lesion location. RESULTS: Most eyelid tumors were epidermal in origin(1080, 48.5%), followed by miscellaneous(885, 39.7%) and adnexal tumors(263, 11.8%). Among all the tumors, 292(13.1%) were malignant lesions, 1910(85.7%) benign and 26(1.1%) premalignant lesions. Most malignant tumors originated from epidermal cells(60.0%), followed by adnexal cells(34.6%). The most common malignant tumors were basal cell carcinomas(56.5%) followed by sebaceous carcinoma(34.6%), squamous cell carcinomas(3.8%) and lymphoma/plasmocytoma(1.7%). The benign and premalignant eyelid lesions mostly originated from epidermal cells(46.4%) followed by miscellaneous cell sources(45.2%), including melanocytic nevus(33.8%), seborrheic keratosis(13.7%), squamous cell papilloma(13.0%) and epidermal cysts(11.5%). CONCLUSION: Eyelid tumors are mostly epithelial in origin. Benign tumors are significantly more common than malignant tumors with an obvious female predominance, and the most frequent malignant tumor are basal cell carcinoma, sebaceous carcinoma and squamous cell carcinomas. The tumor clinical features varied among the different subtypes.

文摘Simultaneous co-firing of the levator palpebrae (LP) and pterygoid muscles were recorded in Marcus Gann Syndrome (MGS) patients in early clinical studies. "Release hypothesis" proposed an intrinsic masticatory oculo- motor neural circuit and this kind circuit, which, however, has been observed only in amphibian. On the other hand, congenital miswiring hypothesis has overwhelmed other interpretations. However, the same phenomenon visualized in MGS cases was unveiled in human subjects without any sign of congenital oculomotor disorder. To further study co-firing of the upper eyelid and jaw muscles, we applied non-invasive EMG recording of the upper eyelid and ipsilateral masseter muscle belly in nine healthy volunteers. LP activity was determined initially by looking upward and active retraction of upper eyelid with head fixed. Then, dual channel inputs from upper eyelid and masseter muscle was recorded during tooth occlusion motivated by isometric masseter muscle contraction without jaw and face moving. The EMG recorded from upper eyelid when the subjects retracted eyelid with head fixed exhibited the same pattern as that collected during tooth occlusion, but the pattern was completely different from EMG of active eye closure. This reflects tooth occlusion evoked LP activity. Then, simultaneous co-firing of the LP and masseter muscle was recorded simultaneously during tooth occlusion without jaw movement. Finally, the aforemen- tioned co-firing was recorded when the subjects conducted rhythmic occlusion and synchronous EMG from both muscles was acquired. In conclusions, humans may also have an intrinsic masticatory oculomotor circuit and release hypothesis may apply, at least, to some cases of MGS.

文摘AIM: To report the long-term outcomes of a large cohort of upper lid retraction patients treated with subconjunctival triamcinolone acetonide injections.METHODS: This retrospective clinical study was conducted from 2009 to 2016. The documents of 97 patients(126 eyes) were reviewed. The patients were treated with subconjunctival triamcinolone acetonide injections monthly and evaluated pre-and post-treatment by taking measurements of the upper margin reflex distance(MRD1, the distance between the upper-lid margin and the pupil center), lid aperture, lagophthalmos and proptosis. The patients were divided into the cured group, the improved group and the ineffective group based on the final treatment effectiveness. The improved group and the ineffective group were combined into non-cured group.RESULTS: The follow-up time was 23.45±14.86 mo. Of the patients, 63(64.9%) were assigned to the cured group, 22(22.7%) in the improved group, 12(12.4%) in the ineffective group. Injection times for cured group was 4.66±1.74, and for non-cured group was 5.17±2.08(P≤0.05). The MRD1 was significantly reduced between baseline and 1 mo after the initiation of treatment in the cured and improved groups(P〈0.001). The values did not change significantly after 4 mo for the improved group, while they continued to decrease in the cured group. In the ineffective group, the MRD1 did not significantly change after treatment. A statistically significant difference was observed between the baseline and post-treatment values of the mean muscle thickness(2.95±0.99 mm vs 2.04±0.63 mm, P〈0.05) and surface area(27.27±10.5 mm2 vs 18.3±7.04 mm2,P〈0.05) of the levator superioris with magnetic resonance imaging examination. Twelve patients(12.4%) relapsed after treatment and required additional subconjunctival injections. The main side effects included menstrual cycle disturbances(32%) and elevations of intra-ocular pressure(18.6%). CONCLUSION: A repeated subconjunctival injection of triamcinolone is an effective and relatively safe treatment for upper lid retraction due to thyroid-associated ophthalmopathy. This is related to the anti-inflammation effect of the medicine and the levator thickness can become thinner. Patients must be monitored regularly for recurrences and side effects.
