AIM:To compare the surgical outcomes of glaucoma drainage device implantation(GDI)and trans-scleral neodymium:YAG cyclophotocoagulation(CPC)in the management of refractory glaucoma after Descemetstripping automated endothelial keratoplasty(DSAEK).METHODS:This retrospective study on observational case series enrolled 29 patients who underwent DSAEK and posterior anti-glaucoma surgery(15 with GDI and 14 with CPC).The main outcome measures were intraocular pressure(IOP),glaucoma surgery success rate(defined as IOP of 6–21 mm Hg without additional anti-glaucoma operation),number of glaucoma medications,endothelial graft status,and best-corrected visual acuity(BCVA).RESULTS:The mean follow-up time was 34.1 and 21.0mo for DSAEK or glaucoma surgeries,both for the GDI and CPC groups.Both groups showed significant IOP reduction after glaucoma surgery.The GDI group presented a significantly higher success rate in IOP control than the CPC group(60%vs 21.4%,P=0.03).Both procedures significantly decreased the number of glaucoma medications(P=0.03).Forty percent and 57%of cases in the GDI and the CPC group,respectively,experienced endothelial graft failure during follow-up(P=0.36).Significantly worse BCVA after surgery was observed in the CPC group but not in the GDI group.CONCLUSION:Both GDI and CPC significantly decrease IOP in eyes with glaucoma after DSAEK.GDI is preferable to CPC in refractory glaucoma cases after DSAEK,as it manifests a significantly higher success rate for IOP control,similar endothelial graft failure rate,and relatively preserves BCVA than CPC. 展开更多

AIMTo evaluate outcomes of combined pars plana vitrectomy and Baerveldt glaucoma implant (PPV-BGI) placement for refractory glaucoma.METHODSThe medical records of 92 eyes (89 patients) that underwent PPV-BGI were retrospectively reviewed, including 43 eyes with neovascular glaucoma (NVG) and 49 eyes with other types of glaucoma (non-NVG).RESULTSOutcome measures were visual acuity (VA), intraocular pressure (IOP), glaucoma medical therapy, complications, and success [VA&#x0003e;hand motions (HM), IOP&#x02265;6 mm Hg and &#x02264;21 mm Hg, no subsequent glaucoma surgery]. Cumulative success rates for the non-NVG group and NVG group were 79% and 40% at 1y, respectively (P=0.038). No difference in the rates of surgical success were found between pars plana and anterior chamber tube placement. Preoperative IOP (mean&#x000b1;SD) was 30.3&#x000b1;11.7 mm Hg in the Non-NVG group and 40.0&#x000b1;10.6 mm Hg in the NVG group, and IOP was reduced to 15&#x000b1;9.5 mm Hg in the non-NVG group and 15&#x000b1;10.5 mm Hg in the NVG at 1y. Number of glaucoma medications (mean&#x000b1;SD) decreased from 2.7&#x000b1;1.3 in the non-NVG group and 2.8&#x000b1;1.3 in the NVG group preoperatively to 0.76&#x000b1;1.18 in the non-NVG group and 0.51&#x000b1;1.00 in the NVG group at 1y. Improvement in VA of &#x02265;2 Snellen lines was observed in 25 (27%) eyes, although only 33% of non-NVG eyes and 2.3% of NVG eyes maintained VA better than 20/200 at 1y. Nonclearing vitreous hemorrhage was the most common postoperative complication occurring in 16 (17%) eyes, and postoperative suprachoroidal hemorrhages developed in 5 (5.4%) eyes.CONCLUSIONPPV-BGI is a viable surgical option for eyes with refractory glaucoma, but visual outcomes are frequently poor because of ocular comorbidities, especially in eyes with NVG. The location of tube placement does not influence surgical outcome and should be left to the discretion of the surgeon. 展开更多

AIM: To evaluate the outcomes of Ahmed glaucoma valve(AGV) implantation surgery for refractory glaucoma.METHODS: This one-armed historical cohort study was conducted in 2011. Refractory glaucoma was defined as eyes with an intraocular pressure(IOP) greater than21 mm Hg with maximally tolerated glaucoma medications, failed surgeries, or both. For all eyes with refractory glaucoma that underwent AGV implantation,data were collected on IOP, the best corrected visual acuity(BCVA) and glaucoma medications preoperatively and 4, 6, 12, 24 and 56 wk postoperatively. Logarithm values of IOP were calculated and compared. RESULTS: The study group was comprised of 30patients(30 eyes, 16 males and 14 females) with refractory glaucoma. Mean preoperative IOP was 39.3 ±13.8 mm Hg. Postoperative mean IOP was 15.7±7.1 mm Hg,19.6 ±12.8 mm Hg and 13.9 ±14.2 mm Hg at 12, 24 and56 wk respectively. BCVA was ≥6/60 in 11 eyes preoperatively, and five eyes had BCVA ≥6/60 at 56 wk postoperatively. Preoperatively, more than four medications were used to treat glaucoma in 21 eyes. At12 wk postoperatively, no medications were required to control IOP in 20 eyes. At 56 wk postoperatively, at least one medication was required to control IOP in 10 eyes.Over the entire follow up period, four eyes were treated with yttrium aluminium garnet(YAG) laser and 14 eyes required a second surgery. The AGV was removed in four eyes.CONCLUSION: AGV implantation reduced IOP and the number of medications required to control refractory glaucoma. However, there was a higher risk of decreased vision. Long-term follow up and prompt intervention are recommended. 展开更多

BACKGROUND Glaucoma is caused by increased intraocular pressure(IOP)that damages the optic nerve,leading to blindness.The Ahmed glaucoma valve(AGV)is a glau-coma drainage implant device that is used in glaucoma patients with uncontrolled IOP.A possible complication after any ocular surgery however is hyphema,which can itself progress to uveitis glaucoma hyphema(UGH)syndrome on rare occasions.UGH syndrome has not yet been reported as a complication of AGV implantation.CASE SUMMARY Here,we have reported a case of a 55-year-old female who developed both hyphema and pigmentation as a result of AGV implantation.We confirmed UGH syndrome secondary to AGV implantation after the patient underwent another surgery to shorten and reposition the AGV tube.After the second surgery,the patient’s IOP was reduced,and she had a clear cornea and no signs of hyphema.CONCLUSION This first report of UGH syndrome as a complication of AGV implantation reminds clinicians that frequent follow-up is paramount. 展开更多

Background: Research exploring the influence of glaucoma on quality of life has gained momentum in recent years. Numerous studies have investigated the multifaceted aspects of quality of life in glaucoma patients, utilizing various assessment tools and methodologies. Objective: To determine the influence that glaucoma has on the quality of life among adult patients. Study site: kitwe teaching eye hospital, Zambia. Method: It was a cross-sectional study that was conducted from 30<sup>th</sup> June 2022 to 17<sup>th</sup> April 2023. The study included 106 diagnosed glaucoma patients who were above the age of 55 years. Data was collected using validated 25-item national eye institute visual function Questionnaire (NEI VFQ-25). The data was analyzed using SPSS version 26 and Microsoft excel to present frequencies and percentages that generated graphical presentation. Results: 62% of the participants worry about their eye sight most of the time, 26% sometimes and 12% a little time. 9% of the participants had little difficulty to read ordinary prints, 14% moderate difficulties and 58% extremely difficult. 40% of the participants could drive despite glaucoma damaging their eyes while 60% could not. Majority of the patients said it was difficult noticing things around them while walking or sitted in one place. There was a significant difference between effects of glaucoma on patients and the existing relationship between glaucoma and quality of life (ANOVA, p = 0.019 and ANOVA, p = 0.023). Conclusion: This study has demonstrated the magnitude of impact that glaucoma has on the Quality of Life (QoL) in diagnosed patients and the relationship between glaucoma and the Quality of Life. Due to the progressive visual loss, the amount of activities these patients would perform is negatively affected especially where social and economic activities are concerned which also affects their monthly earnings for those living in middle to low-income countries. Therefore, social welfare and psycho-social institutions need to increase their support for these glaucoma patients. 展开更多

AIM:To investigate the association between juvenile open angle glaucoma(JOAG)and mental health among Koreans.METHODS:This study used nationally representative data from the 8th Korea National Health and Nutrition Examination Survey(KNHANES)2021.Glaucoma diagnosis followed the International Society of Geographical and Epidemiological Ophthalmology criteria based on glaucomatous structural defects,visual field defects,corrected vision,and intraocular pressure.As outcomes,suicidal behaviors,psychiatric counseling,and depression were evaluated through mental health questionnaires.Odds ratios(ORs)with 95%confidence intervals(CIs)were estimated using logistic regression models,adjusting for covariates.RESULTS:Among 7090 participants,3446 met the inclusion criteria for analysis,and 88(2.6%)were diagnosed with open angle glaucoma(OAG).After adjusting for age,sex,and best-corrected visual acuity(VA),participants with OAG were revealed to have significantly higher odds of suicidal behaviors(i.e.,ideation,planning,or attempts)compared with those without OAG(OR:2.70;95%CI:1.12-6.54;P=0.028).This association remained significant after further adjustments for socioeconomic status,lifestyle factors,and presence of chronic conditions(P=0.031 and 0.035,respectively).However,there was no significant difference for the other two outcomes,psychiatric counseling and depression.An age-stratified analysis revealed a stronger association between OAG and suicidal behaviors in younger JOAG participants(<40y)than in older OAG participants(≥40y;OR:3.80 vs 2.22;95%CI:0.79-18.22 vs 0.56-8.80,respectively).CONCLUSION:OAG patients show a higher risk of suicidal behaviors than those without glaucoma particularly in JOAG patients. 展开更多

BACKGROUND Many patients with ulcerative colitis(UC)do not respond well to,or tolerate conventional and biological therapies.There is currently no consensus on the treatment of refractory UC.Studies have demonstrated that the selective Janus kinase 1 inhibitor upadacitinib,a small-molecule drug,is effective and safe for treating UC.However,no studies have revealed that upadacitinib is effective in treating refractory UC with primary nonresponse to infliximab and vedolizumab.CASE SUMMARY We report the case of a 44-year-old male patient with a chief complaint of bloody diarrhoea with mucus and pus,in addition to dizziness.The patient had recurrent disease after receiving mesalazine,prednisone,azathioprine,infliximab and vedolizumab over four years.Based on the endoscopic findings and pathological biopsy,the patient was diagnosed with refractory UC.In particular,the patient showed primary nonresponse to infliximab and vedolizumab.Based on the patient’s history and recurrent disease,we decided to administer upadacitinib.During hospitalisation,the patient was received upadacitinib under our guidance.Eight weeks after the initiation of upadacitinib treatment,the patient’s symptoms and endoscopic findings improved significantly.No notable adverse reactions have been reported to date.CONCLUSION Our case report suggests that upadacitinib may represent a valuable strategy for treating refractory UC with primary nonresponse. 展开更多

There is a certain failure rate in traditional glaucoma surgery because of the lack of depth information in microscope images.In this work,we present a digital microscope-integrated optical coherence tomography(MIOCT)system and several custom-made OCT-compatible instruments for glaucoma surgery.Sixteen ophthalmologists were asked to perform trabeculectomy and canaloplasty on live porcine eyes using the system and instruments.After surgery,a subjective feedback survey about the user experience was taken.The experiment results showed that our system can help surgeons easily locate important tissue structures during surgery.The custom-made instruments also solved the shadowing problem in OCT imaging.Surgeons preferred to use the system in their future practice. 展开更多

Glutamate excitotoxicity has been shown to play an important role in glaucoma, and glutamate can induce ferroptosis. The p38 mitogenactivated protein kinase(MAPK) pathway inhibitor SB202190 has a potential ability to suppress ferroptosis, and its downstream targets, such as p53, have been shown to be associated with ferroptosis. However, whether ferroptosis also occurs in retinal ganglion cells in response to glutamate excitotoxicity and whether inhibition of ferroptosis reduces the loss of retinal ganglion cells induced by glutamate excitotoxicity remain unclear. This study investigated ferroptosis in a glutamate-induced glaucoma rat model and explored the effects and molecular mechanisms of SB202190 on retinal ganglion cells. A glutamate-induced excitotoxicity model in R28 cells and an N-methyl-D-aspartate-induced glaucoma model in rats were used. In vitro experiments showed that glutamate induced the accumulation of iron and lipid peroxide and morphological changes of mitochondria in R28 cells, and SB202190 inhibited these changes. Glutamate induced the levels of p-p38 MAPK/p38 MAPK and SAT1 and decreased the expression levels of ferritin light chain, SLC7A11, and GPX4. SB202190 inhibited the expression of iron death-related proteins induced by glutamate. In vivo experiments showed that SB202190 attenuated N-methyl-D-aspartate-induced damage to rat retinal ganglion cells and improved visual function. These results suggest that SB202190 can inhibit ferroptosis and protect retinal ganglion cells by regulating ferritin light chain, SAT1, and SLC7A11/Gpx4 pathways and may represent a potential retina protectant. 展开更多

Glaucoma,a prevalent and debilitating eye disease,has long been associated with vision impairment and blindness.However,recent research has shed light on the often-underestimated psychological dimensions of this condition.Anxiety and depression,two pervasive psychiatric comorbidities,have been increasingly recognized among glaucoma patients.This comprehensive review aims to explore the intricate relationship between psychiatry and ophthalmology,in the context of managing depression and anxiety in glaucoma patients.By meticulously examining peer-reviewed literature,we synthesize current knowledge on the prevalence,risk factors,and underlying mechanisms of anxiety and depression in glaucoma.The evidence reveals that glaucoma patients face an elevated risk of experiencing these mood disorders.Factors such as progressive vision loss,complex medication regimens,and the fear of further visual deterioration contribute to their vulnerability.Moreover,we delve into the bidirectional relationship between glaucoma and mood disorders,shedding light on the complex interplay between ocular and emotional health.Our review investigates the implications of anxiety and depression on glaucoma management,including their potential impact on treatment adherence,disease progression,and overall quality of life.We also explore the neurobiological pathways linking glaucoma and mood disorders,providing a foundation for future research and potential therapeutic interventions.In conclusion,recognizing the psychological burden carried by glaucoma patients is essential for holistic and patient-centered care.This review underscores the pressing need for integrated approaches that bring together ophthalmological and psychiatric expertise to optimize the well-being of individuals facing the challenges of glaucoma.By addressing anxiety and depression in glaucoma care,healthcare providers can enhance the overall quality of life for these patients,ultimately leading to improved outcomes and a brighter future for those affected by this condition.This review offers valuable insight for healthcare practitioners and researchers,providing a concise overview of key topics and research in the field of managing depression and anxiety in glaucoma patients. 展开更多

AIM:To report a one-year clinical outcomes of low-dose laser cycloplasty(LCP)among malignant glaucoma patients.METHODS:In this prospective,multicenter,noncomparative clinical study,participants with malignant glaucoma were recruited and underwent LCP at eight ophthalmic centers in China.Patients were followed up at 1wk,1,3,6,and 12mo.Intraocular pressure(IOP),number of glaucoma medications,anterior chamber depth(ACD),and complications were recorded.Anatomical success was defined as the reformation of the anterior chamber based on slit-lamp biomicroscopy.Recurrence was defined by the presence of a shallow orflat anterior chamber after initial recovery from treatment.RESULTS:A total of 34 eyes received LCP.Mean IOP and medications decreased from 36.1±11.5 mm Hg with 3.3±1.5 glaucoma medications pre-treatment to 20.9±9.8 mm Hg(P<0.001)with 2.9±1.6 medications(P=0.046)at 1d,and 17.4±6.7 mm Hg(P<0.001)with 1.3±1.7 medications(P<0.001)at 12mo.The ACD increased from 1.1±0.8 mm at baseline to 1.7±1.0 mm and to 2.0±0.5 mm at 1d and 12mo,respectively.A total of 32(94.1%)eyes achieved initial anatomical success.During follow-up,2(5.9%)eyes failed and 8(23.5%)eyes relapsed,yielding a 12-month anatomical success rate of 64.3%.Complications including anterior synechia(8.82%),choroidal/ciliary detachment(5.88%)and hypopyon(2.94%)were observed within 1wk.CONCLUSION:LCP is simple,safe,and effective in reforming the anterior chamber in malignant glaucoma. 展开更多
