This association suggests a link between them and between their treatments. Our purpose for this study is to determine the prevalence of dry eye in our glaucoma patients treated with eye drops and deduce the factors associated with it. Patients and Methods: We conducted a cross-sectional, analytical study from October 2022 to September 2023 in the ophthalmology department of Garoua Regional Hospital in glaucoma patients aged over 15 years able to answer the Ocular Surface Disease Index (OSDI) questionnaires and treated with antiglaucoma eye drops for more than 3 months. These patients underwent a complete ophthalmological examination and a tear film break-up time test. Results: A total of 73 patients (146 eyes) were examined. The average age of the patients was 47.2 ± 16.5 years, with a male predominance of 54.8%. The prevalence of dry eye syndrome in our patients according to the OSDI score was 56.2% (95% CI) (44.8;67.6). The prevalence of dry eye syndrome on clinical examination of the BUT in the right eye was 83.7% (95% CI) (75.1;92.1) and 79.4% (70.2;88.7) in the left eye. The duration of antiglaucoma treatment was the factor associated with dry eye syndrome (p < 0.05) in glaucoma patients in our setting. Conclusion: Dry Eye Syndrome is common in glaucoma patients on drops in our setting. Treatment duration of more than 1 year seems to be associated with dry eyes.展开更多

Sixty subjects with mean age of 45.89 years who had symptoms and signs of dry eye were enrolled in this prospective, investigator-masked and stratified random sampling study. The subjects were divided into two parallel groups with 30 subjects (60 eyes) in each group. One group received carbomer gel, and the other group received 1% CMC containing artificial tears. Subjects received the drops 3 to 4 times or more per day for 3 months. At the first visit time, the precorneal residence time of these two drops was measured. The efficacy was assessed by comparing the subjective symptoms (ocular dry- ness, foreign body sensation, burning sensation and pain), and the objective test results of tears breakup time, Schirmer's test and corneal fluorescein staining prior to the study and after the treat- ment. As a result, the ocular residence time of carbomer gel was significantly longer than that of 1% CMC (P〈0.001). Most of the primary subjective symptoms and objective test results were improved after treatment in both carbomer gel group and 1% CMC group. As to the improvement of each symptom and objective test result, carbomer gel was more effective than 1% CMC group (P〈0.01). In conclusion, carbomer gel had longer precorneal residence time and was more effective than 1% CMC in the treatment of patients with dry eyes.展开更多

Patients were divided into subjects treated with topical 0.05% CsA and preservative free sodium hyaluronate vehicle(experimental group, n=74 eyes) and subjects treated with the preservative free sodium hyaluronate vehicle(control group, n=32 eyes). They were evaluated at baseline and 1, 2, and 3 mo for subjective symptoms and objective signs including tear film break-up time(t BUT), Schirmer test, corneal staining(CS) score, lid margin telangiectasia(LMT), meibomian gland secretion(MGS), and conjunctival injection(CI).RESULTS: In the short-term treatment, the experimental group showed a statistically significant improvement in the ocular surface disease index(OSDI; P〈0.001), tBUT(P=0.004), Schirmer test score(P=0.008) and LMT(P=0.021) by repeated measure ANOVA. Additionally, mean changes from baseline in OSDI(P〈0.001), tBUT(P=0.001), Schirmer test score(P=0.029), CS score(P=0.047), LMT(P=0.002), CI(P=0.030) were improved better in the experimental group than in the control group at 3 mo. However, there was no significant difference between the two groups in MGS(P=0.67).CONCLUSION: In dry eyes with MGD, 0.05% CsA improves the tear film stability as well as subjective ocular discomfort, and is effective in controlling lid margin inflammation.展开更多

The differences of the above parameters between the two groups were examined, and the relationship between corneal biomechanics and tear film parameters were observed. RESULTS:The differences in age, sex, intraocular pressure(IOP) and central corneal thickness(CCT) were not significant between the two groups(P〉0.05). The tear film parameters had significant differences between the SSDE group and NSSDE group(all P〈0.05). Patients in the SSDE group had significantly lower A1-time and HC-time, but higher DA(P=0.01, 0.02, and 0.02, respectively) compared with the NSSDE group. In the SSDE group, DA was negatively correlated with TBUT(rho=-0.38, P=0.03); HC-time was negatively correlated with CSS(rho=-0.43, P=0.02). In the NSSDE group, HC-time was again negatively correlated with CSS(rho=-0.39, P=0.02).CONCLUSION:There are differences in corneal biomechanical properties between SSDE and NSSDE. The cornea of SSDE tends to show less "stiffness", as seen by a significantly shorter A1-time and HC-time, but larger DA, compared with the cornea of NSSDE. Biomechanical parameters can be influenced by different tear film parameters in both groups.展开更多

文摘Background: Dry eye and glaucoma are two common pathologies in the elderly, and are very often associated. This association suggests a link between them and between their treatments. Our purpose for this study is to determine the prevalence of dry eye in our glaucoma patients treated with eye drops and deduce the factors associated with it. Patients and Methods: We conducted a cross-sectional, analytical study from October 2022 to September 2023 in the ophthalmology department of Garoua Regional Hospital in glaucoma patients aged over 15 years able to answer the Ocular Surface Disease Index (OSDI) questionnaires and treated with antiglaucoma eye drops for more than 3 months. These patients underwent a complete ophthalmological examination and a tear film break-up time test. Results: A total of 73 patients (146 eyes) were examined. The average age of the patients was 47.2 ± 16.5 years, with a male predominance of 54.8%. The prevalence of dry eye syndrome in our patients according to the OSDI score was 56.2% (95% CI) (44.8;67.6). The prevalence of dry eye syndrome on clinical examination of the BUT in the right eye was 83.7% (95% CI) (75.1;92.1) and 79.4% (70.2;88.7) in the left eye. The duration of antiglaucoma treatment was the factor associated with dry eye syndrome (p < 0.05) in glaucoma patients in our setting. Conclusion: Dry Eye Syndrome is common in glaucoma patients on drops in our setting. Treatment duration of more than 1 year seems to be associated with dry eyes.
文摘The present study aimed to compare the clinical efficacy of a 0.4% carbomer gel and 1% carboxymethyl cellulose (CMC) containing artificial tears in treatment of dry eye patients. Sixty subjects with mean age of 45.89 years who had symptoms and signs of dry eye were enrolled in this prospective, investigator-masked and stratified random sampling study. The subjects were divided into two parallel groups with 30 subjects (60 eyes) in each group. One group received carbomer gel, and the other group received 1% CMC containing artificial tears. Subjects received the drops 3 to 4 times or more per day for 3 months. At the first visit time, the precorneal residence time of these two drops was measured. The efficacy was assessed by comparing the subjective symptoms (ocular dry- ness, foreign body sensation, burning sensation and pain), and the objective test results of tears breakup time, Schirmer's test and corneal fluorescein staining prior to the study and after the treat- ment. As a result, the ocular residence time of carbomer gel was significantly longer than that of 1% CMC (P〈0.001). Most of the primary subjective symptoms and objective test results were improved after treatment in both carbomer gel group and 1% CMC group. As to the improvement of each symptom and objective test result, carbomer gel was more effective than 1% CMC group (P〈0.01). In conclusion, carbomer gel had longer precorneal residence time and was more effective than 1% CMC in the treatment of patients with dry eyes.

文摘AIM: To investigate the efficacy of combined topical 0.05% cyclosporine A(CsA; Restasis~?, Allergan pharmaceuticals, USA) and 0.1% sodium hyaluronate treatment in dry eyes with meibomian gland dysfunction(MGD).METHODS: In a retrospective analysis, 53 patients(106 eyes) with MGD were enrolled and performed lid warm massage for 10 min daily and be instilled preservative free sodium hyaluronate 0.1% eye drops 4 times daily. Patients were divided into subjects treated with topical 0.05% CsA and preservative free sodium hyaluronate vehicle(experimental group, n=74 eyes) and subjects treated with the preservative free sodium hyaluronate vehicle(control group, n=32 eyes). They were evaluated at baseline and 1, 2, and 3 mo for subjective symptoms and objective signs including tear film break-up time(t BUT), Schirmer test, corneal staining(CS) score, lid margin telangiectasia(LMT), meibomian gland secretion(MGS), and conjunctival injection(CI).RESULTS: In the short-term treatment, the experimental group showed a statistically significant improvement in the ocular surface disease index(OSDI; P〈0.001), tBUT(P=0.004), Schirmer test score(P=0.008) and LMT(P=0.021) by repeated measure ANOVA. Additionally, mean changes from baseline in OSDI(P〈0.001), tBUT(P=0.001), Schirmer test score(P=0.029), CS score(P=0.047), LMT(P=0.002), CI(P=0.030) were improved better in the experimental group than in the control group at 3 mo. However, there was no significant difference between the two groups in MGS(P=0.67).CONCLUSION: In dry eyes with MGD, 0.05% CsA improves the tear film stability as well as subjective ocular discomfort, and is effective in controlling lid margin inflammation.

文摘AIM:To compare the corneal biomechanics of Sj?gren's syndrome(SS) and non-SS dry eyes with Corneal Visualization Scheimpflug Technology(CorV is ST).METHODS:Corneal biomechanics and tear film parameters, namely the Schirmer I test value, tear film break-up time(TBUT) and corneal staining score(CSS) were detected in 34 eyes of 34 dry eye patients with SS(SSDE group) and 34 dry eye subjects without SS(NSSDE group) using CorV is ST. The differences of the above parameters between the two groups were examined, and the relationship between corneal biomechanics and tear film parameters were observed. RESULTS:The differences in age, sex, intraocular pressure(IOP) and central corneal thickness(CCT) were not significant between the two groups(P〉0.05). The tear film parameters had significant differences between the SSDE group and NSSDE group(all P〈0.05). Patients in the SSDE group had significantly lower A1-time and HC-time, but higher DA(P=0.01, 0.02, and 0.02, respectively) compared with the NSSDE group. In the SSDE group, DA was negatively correlated with TBUT(rho=-0.38, P=0.03); HC-time was negatively correlated with CSS(rho=-0.43, P=0.02). In the NSSDE group, HC-time was again negatively correlated with CSS(rho=-0.39, P=0.02).CONCLUSION:There are differences in corneal biomechanical properties between SSDE and NSSDE. The cornea of SSDE tends to show less "stiffness", as seen by a significantly shorter A1-time and HC-time, but larger DA, compared with the cornea of NSSDE. Biomechanical parameters can be influenced by different tear film parameters in both groups.
文摘BACKGROUND Dry eye syndrome(DES)is a common disease with various clinical manifestations.DES had a significant association with diabetes.Blink reflex(BR)is also known as trigeminal nerve facial reflex.The stimulation of corneal nerves is one of the origins of BR stimulation.The parasympathetic fibers sent out through the facial nerve are the outlet of tear reflexes.BR can be used to assess the function of the corneal nerve closed-loop;however,whether the BR changes in these patients is unclear.AIM To understand the morphology and function of the corneal nerve in patients with dry eyes having diabetes or not.METHODS This study enrolled 131 patients who visited the inpatient and outpatient services of ophthalmology and endocrinology departments between January 2019 to August 2020 with subjective symptoms of dry eyes and non-dry eye reasons,as well as volunteers such as colleagues.The patients were divided into four groups:DEwDM,with dry eyes having type 2 diabetes mellitus(T2DM);DMnDE,with T2DM not having dry eyes;DEnDM,with dry eyes not having diabetes;and nDMnDE,with neither dry eyes nor diabetes.The tear film break-up time,Schirmer I test,in vivo confocal microscopy,and BR were performed.RESULTS The DEwDM,DMnDE,DEnDM,and nDMnDE groups included 56,22,33,and 20 patients,respectively.Sex and age were not statistically different among the four groups.The nerve fiber length(NFL)of patients in the DEwDM,DEnDM,and DMnDE groups reduced(P<0.001,P=0.014,and P=0.001,respectively).No significant difference in corneal nerve fiber density(NFD)(P=0.083)and corneal nerve branch density(NBD)(P=0.195)was found among the four groups.The R1 Latency of blink reflexes increased only in the DEwDM group(P=0.008,P=0.001,P<0.001,compared with the DMnDE,DEnDM,and nDMnDE groups,respectively).The NBD and R1 Latency were different between DEwDM and DEnDM groups in patients with moderate and severe dry eyes.CONCLUSION The corneal nerve morphology changed in patients with dry eyes or diabetes,or with both,while the function of corneal nerve closed-loop reduced only in those with dry eyes and diabetes.

文摘Dry eye disease(DED)is a major ocular pathology worldwide,causing serious ocular discomfort and even visual impairment.The incidence of DED is gradually increasing with the highfrequency use of electronic products.Although inflammation is core cause of the DED vicious cycle,reactive oxygen species(ROS)play a pivotal role in the vicious cycle by regulating inflammation from upstream.Therefore,current therapies merely targeting inflammation show the failure of DED treatment.Here,a novel dual-atom nanozymes(DAN)-based eye drops are developed.The antioxidative DAN is successfully prepared by embedding Fe and Mn bimetallic single-atoms in N-doped carbon material and modifying it with a hydrophilic polymer.The in vitro and in vivo results demonstrate the DAN is endowed with superior biological activity in scavenging excessive ROS,inhibiting NLRP3 inflammasome activation,decreasing proinflammatory cytokines expression,and suppressing cell apoptosis.Consequently,the DAN effectively alleviate ocular inflammation,promote corneal epithelial repair,recover goblet cell density and tear secretion,thus breaking the DED vicious cycle.Our findings open an avenue to make the DAN as an intervention form to DED and ROSmediated inflammatory diseases.

文摘●AIM:To investigate the underlying mechanism of dry environment(autumn dryness)affecting the lacrimal glands in rats.●METHODS:Twenty Sprague-Dawley rats were randomly divided into two groups.The rats were fed in specific pathogen free environment as the control group(n=10),and the rats fed in dry environment as the dryness group(n=10).After 24d,lacrimal glands were collected from the rats.The tissues morphology was observed by hematoxylineosin(HE)staining.Tandem mass tags(TMT)quantitative proteomics analysis technology was used to screen the differential expressed proteins of lacrimal glands between the two groups,then bioinformatics analysis was performed.Further,the immunohistochemical(IHC)method was used to verify the target proteins.●RESULTS:In dryness group,the lacrimal glands lobule atrophied,the glandular cavities enlarged,the sparse nuclear distribution and scattered inflammatory infiltration between the acinus were observed.The proteomics exhibited that a total of 195 up-regulated and 236 downregulated differential expressed proteins screened from the lacrimal glands of rats.It was indicated that the biological processes(BP)of differential expressed proteins mainly included cell processes and single BP.The cellular compositions of differential expressed proteins mainly located in cells,organelles.The molecular functions of differential expressed proteins mainly included binding,catalytic activity.Moreover,the Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis showed that the differential expressed proteins mainly involved lysosome,complement and coagulation cascade,and ribosome pathway.The IHC result verified that the up-regulated expression proteins of Protein S100A9(S100A9),Annexin A1(Anxa1),and Clusterin(Clu)in lacrimal glands of rats in dryness group were higher than control group.●CONCLUSION:The up-regulated expression proteins of S100A9,Anxa1,and Clu may be the potential mechanisms of dry eye symptoms caused by dry environment.This study provides clues of dry environments causing eye-related diseases for further studies.
文摘AIM:To compare high or low concentration of hyaluronic acid eye drops(HY)for dry eye syndromes(DES).METHODS:Randomized controlled trials(RCTs)comparing various concentrations of HY were searched in PubMed,Embase,Web of Science,Cochrane,SinoMed,CNKI,Wanfang Database,CQVIP,and Chinese journals databases between inception and July 2023.Pooled standardized mean differences(SMD)or weighted mean difference(WMD)with 95%confidence intervals(CI)from RCTs evaluating Schirmer’s I test(SIT),corneal fluorescein staining score(CFS),tear breakup time(TBUT),DES score(DESS),and Ocular Surface Disease Index(OSDI)were calculated.Sensitivity analysis,Egger’s test and Meta-regression analysis were performed for all indicators.RESULTS:We conducted a Meta-analysis of 10 RCTs that met the inclusion criteria,involving 1796 cases.High-concentrations group significantly improved the outcome of CFS according to random effects modelling(SMD,-3.37;95%CI,-5.25 to-1.48;P=0.0005).The rest of the results were not statistically significant,including indicators such as SIT,TBUT,DESS and OSDI.CONCLUSION:For dry eyes with positive corneal staining,a high concentration of HY is recommended,whereas in other cases,a high concentration of HY does not offer a more pronounced advantage over a low concentration of HY in the treatment of dry eyes.
文摘AIM:To determine the dry eye(DE)rate and its relationship with disease stage in patients with primary hypertension.METHODS:A cross-sectional study included 432 patients with primary hypertension(with an equal number of patients in each group:144 in stage Ⅰ,Ⅱ,and Ⅲ hypertension)and 144 healthy subjects as a control group.The Ocular Surface Disease Index(OSDI)and Schirmer Ⅰ test without anesthetics were conducted on all 576 subjects.Subjects with OSDI scores<13 and Schirmer Ⅰ values equal to or under 10 mm were diagnosed with DE.RESULTS:The ratio of DE in hypertension patients was higher than in the control group(41.7%versus 18.8%;P<0.001).The proportion of patients with DE increased gradually according to the hypertension stage:27.1% in stage Ⅰ,40.3% in stage Ⅱ,and 57.6% in stage Ⅲ,P<0.001.Age,duration of hypertension,plasma urea,creatinine,and high-sensitivity C-reactive protein(CRP-hs)levels in hypertension patients with DE were higher than those without DE,P<0.001.Advanced age,a long duration of hypertension,diabetes mellitus,elevated plasma creatinine,and CRP-hs levels were independent factors associated with DE in primary hypertension patients,P<0.001.CONCLUSION:DE is a common disorder associated with advanced age,a long duration of hypertension,diabetes mellitus,elevated plasma CRP-hs,and creatinine levels in patients with primary hypertension.
文摘AIM:To evaluate dry eye disease(DED)symptomatology and mental health status in different COVID-19 patients.METHODS:A cross-sectional observational design was used.Totally 123 eligible adults(46.34%of men,age range,18-59y)with COVID-19 included in the study from August to November,2022.Ocular Surface Disease Index(OSDI),Five-item Dry Eye Questionnaire(DEQ-5),Hospital Anxiety and Depression Scale(HADS),and Pittsburgh Sleep Quality Index(PSQI)were used in this study.RESULTS:OSDI scores were 6.82(1.25,15.91)in asymptomatic carriers,7.35(2.50,18.38)in mild cases,and 16.67(4.43,28.04)in recurrent cases,with 30.00%,35.56%,and 57.89%,respectively evaluated as having DED symptoms(χ2=7.049,P=0.029).DEQ-5 score varied from 2.00(0,6.00)in asymptomatic carriers,3.00(0,8.00)in mild cases,and 8.00(5.00,10.00)in recurrent cases,with 27.50%,33.33%,and 55.26%,respectively assessed as having DED symptoms(χ2=8.532,P=0.014).The prevalence of clinical anxiety(50.00%)and depression(47.37%)symptoms were also significantly higher in patients with recurrent infection(χ2=24.541,P<0.001;χ2=30.871,P<0.001).Recurrent infection was a risk factor for high OSDI scores[odds ratio,2.562;95%confidence interval(CI),1.631-7.979;P=0.033]and DEQ-5 scores(odds ratio,3.353;95%CI,1.038-8.834;P=0.043),whereas having a fixed occupation was a protective factor for OSDI scores(odds ratio,0.088;95%CI,0.022-0.360;P=0.001)and DEQ-5 scores(odds ratio,0.126;95%CI,0.039-0.405;P=0.001).CONCLUSION:Patients with recurrent COVID-19 have more severe symptoms of DED,anxiety,and depression.

文摘AIM:To psychometrically validate the Chinese version of the dry eye-related quality-of-life score questionnaire(DEQSCHN)among Chinese patients with dry eye.METHODS:This study involved 231 participants,including 191 with dry eye disease(DED)comprising the dry eye disease group,and 40 healthy participants forming the control group.Participants were required to complete the DEQS-CHN,and Chinese dry eye questionnaire and undergo clinical tests including the fluorescein breakup time(FBUT),corneal fluorescein staining(CFS),and Schirmer I test.To assess the internal consistency and retest reliability,Cronbach’sαand the intraclass correlation coefficient(ICC)were employed.Content validity was assessed by item-level content validity index(ICV)and an average scale-level content validity index(S-CVI/Ave).Construct validity was assessed by confirmatory factor analysis.The concurrent validity was assessed by calculating correlations between DEQS-CHN and Chinese dry eye questionnaire.Discriminative validity was evaluated through nonparametric tests,with receiver operating characteristic(ROC)curve serving as conclusive indicators of the questionnaire’s distinguishing capability.RESULTS:The Cronbach’sαcoefficients for frequency and degree of ocular symptoms,impact on daily life,and summary score were 0.736,0.704,0.811,0.818,0.861,and 0.860,respectively,and the ICC were 0.611,0.677,0.715,0.769,0.711,and 0.779,respectively.All I-CVI scores ranged from 0.833 to 1.000,with an S-CVI/Ave of 0.956.Confirmatory factor analysis results exhibited a wellfitting model consistent with the original questionnaire[χ^(2)/df=2.653,incremental fit index(IFI)=0.924,comparative fit index(CFI)=0.924,Tucker-Lewis index(TLI)=0.909,and root mean square error of approximation(RMSEA)=0.065].There was a moderate positive correlation between the DEQS-CHN and the Chinese dry eye questionnaire(r^(2)=0.588).The dry eye group demonstrated significantly higher scores compared to the control group,and the area under the curve(AUC)value was 0.8092.CONCLUSION:The DEQS-CHN has been demonstrated as a valid and reliable instrument for assessing the impact of dry eye disease on the quality of life among Chinese individuals with DED.
文摘BACKGROUND Dry eye is a common eye disease.Artificial tears supplements are widely used for the treatment of dry eyes.However,multiple adverse effects have been observed in patients receiving long-term treatment with artificial tears,which may affect the therapeutic effect.AIM To analyze the characteristics of interleukin-1β(IL-1β),interleukin-6(IL-6),and tumor necrosis factor-alpha(TNF-α)levels in patients with dry eye and the therapeutic effect of artificial tears combined with cyclosporine A.METHODS A total of 124 dry eye patients treated at The First People’s Hospital of Xining from April 2020 to April 2022 were selected as the observation group,while 20 healthy individuals served as the control group during the same period.Levels of inflammatory markers,including IL-1β,IL-6,and TNF-α,were analyzed.The observation group was further divided into a study group and a control group,each consisting of 62 patients.The control group received artificial tears,whereas the study group received a combination of artificial tears and cyclosporine A.Inflammatory markers,Schirmer’s test(SIT),tear break-up time(TBUT),corneal fluorescein staining(CFS),National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25)scores,and adverse events(AEs)were compared between the two groups.RESULTS The observation group exhibited significantly elevated serum levels of IL-1β,IL-6,and TNF-αin comparison to the healthy group.Following treatment,the study group demonstrated substantial reductions in IL-1β,IL-6,and TNF-αlevels relative to the control group.Moreover,after treatment,the study group experienced a marked decrease in CFS scores and significant increases in both SIT and BUT levels when compared to the control group.Additionally,significant improvements were observed in the primary symptom of dry eye and secondary symptoms such as photophobia,foreign body sensation,fatigue,red eye,and burning sensation within the study group.Furthermore,post-treatment NEI-VFQ-25 scores across all dimensions exhibited significant enhancements in the study group compared to the control group(P<0.05).It is noteworthy that significant AEs were reported in both groups throughout the treatment period.CONCLUSION Cyclosporine A combined with artificial tears is effective in treating dry eye,yielding enhanced outcomes by improving SIT and TBUT levels,reducing CFS scores,and ameliorating vision-related quality of life.
文摘AIM:To investigate the current situation and influencing factors of self-management ability in dry eye patients in west China.METHODS:A total of 265 patients clinically diagnosed with dry eye received a convenience survey questionnaire at West China Hospital of Sichuan University.All participants completed the rating scale of health self-management skill for adults(AHSMSRS),Huaxi Emotional-Distress Index(HEI),e-health literacy scale(e-HEALS)and Brief Illness Perception Questionnaire(Brief-IPQ).A generalized linear model was employed to establish a multivariate linear model with demographic data,psychological state,e-HEALS,and illness perception as independent variables and health selfmanagement skill score as the dependent variable.RESULTS:The mean score for health self-management skill was 165.58±15.79.Multivariate analysis revealed that advanced age,better illness perception and improved psychological state were associated with better health selfmanagement ability among dry eye patients.Furthermore,the health self-management ability of patients with a disease duration less than 1y was found to be higher compared to those with a disease duration exceeding 1y.CONCLUSION:The health self-management ability of dry eye patients in west China is relatively high.Age,duration of disease,illness perception and psychological state are the influencing factors on the health selfmanagement ability of dry eye patients.
文摘AIM:To quantify the severity and frequency of ocular pain in Tibetan plateau patients with dry eye,and to evaluate the related factors affecting ocular pain.METHODS:A retrospective study included 160 cases of dry eye disease(DED)patients who were treated from July 2022 to June 2023.Age,gender,occupation,illness course,anxiety,plateau duration,plateau protection,ocular surface disease index scale(OSDI),break-up time(BUT),Schirmer I test(SIT),conjunctivitis,history of ophthalmic medication,autoimmune disease,the workload of daily near vision range,smoking and overnight stay were obtained via comprehensive ophthalmic assessment,and their duration was followed up.Logistic regression analysis was used to determine the related factors affecting ocular pain.RESULTS:Totally 77.5%(124/160)of DED patients had ocular pain,of which the severity of ocular pain was mild,moderate,and severe in 30.0%,36.3%,and 11.3%of patients,respectively.Frequency of ocular pain was reported occasional,half the time,frequent,and persistent pain in 19.4%,36.9%,16.9%,and 4.4%.OSDI score was 19.67±5.70(13 to 36),and the level of pain was lowly correlated with OSDI(rs=0.316,P<0.001).Logistic regression showed that in plateau DED patients,increased anxiety led to increased severity and frequency of ocular pain[odds ratio(OR)=3.662,5.613,2.387,and 4.870;all P<0.05],professional eye protection and improvement of daily sleep quantity decreased pain(OR=0.307,0.572,0.418,and 0.789;all P<0.05),while smoking and general protection of plateau did not affect the severity and frequency of ocular pain(all P>0.05).CONCLUSION:Ocular pain is a common complaint in high-altitude DED patients during the pandemic.Anxiety,eye protection,and adequate sleep during the epidemic period are significantly associated with the severity and frequency of ocular pain in patients with plateau DED,while symptoms of DED have relatively little influence on them.
文摘AIM:To explore ocular surface manifestations of dry eye disease(DED)and its influencing factors in systemic lupus erythematosus(SLE)patients.METHODS:Ophthalmological examinations were conducted in SLE patients(n=43)and controls(n=41),including Ocular Surface Disease Index(OSDI),objective scatter index(OSI),tear meniscus height(TMH),lipid layer thickness(LLT),non-invasive Keratograph tear breakup time(NIKBUT),corneal fluorescein score(CFS),Schirmer I test.DED was diagnosed according to the Tear Film and Ocular Surface Society Dry Eye Workshop II Criteria.SLE patients were further divided into DED group and non-DED group,the disease activity,clinical manifestations and laboratory investigations were compared between the two groups.The disease activity was evaluated by Systemic Lupus Erythematosus Disease Activity Index 2000(SLEDAI-2K).Receiver operative characteristic(ROC)curve and multiplefactor binary logistic regression were performed.RESULTS:SLE patients showed higher OSDI[9.1(2.8-15.9)vs 6.3(2.2-7.5),P=0.035],higher OSI[1.67(1.09-2.60)vs 0.96(0.87-1.60),P=0.001],higher CFS[1(0-2)vs 0(0-1),P=0.001],lower LLT[65(42-100)vs 100(79.5-100),P=0.010],and lower NIKBUT[8.03(4.02-9.73)vs 9.67(5.26-12.71),P=0.030]than controls.The 32.6%of SLE patients had DED,which was higher than 12.2%of healthy controls.DED group showed higher SLEDAI-2K score[9.7±6.1 vs 5.4±3.4,P=0.025],higher anti-cardiolipin antibody(ACL)[8.7(3.5-13.2)vs 3.6(2.0-6.9),P=0.035],and higher proportion of patients with cutaneous eruption[42.9%vs 6.9%,P=0.015]than non-DED group.According to multiple-factor binary logistic regression analysis,the SLEDAI-2K score(OR=1.194,P=0.041)and cutaneous eruption(OR=7.094,P=0.045)could be consider as risk factors for DED in SLE patients.The ROC curve of the combined factors including age,disease duration,SLEDAI-2K score,ACL,and cutaneous eruption was analyzed,with a sensitivity of 0.786,a specificity of 0.793,and an area under curve of 0.820.CONCLUSION:Ocular surface affection is frequent in SLE patients,and patients with high disease activity and cutaneous eruption show increased risk of DED.
