Purpose: To investigate whether patients with thyroid disease are at increased risk of uveitis.Methods: Data was collected from the Taiwan National Health Insurance system and included patients newly diagnosed with thyroid disease from 2000 to 2012. The endpoint of interest was a diagnosis of uveitis.Results: In analyzing 21,396 patients with thyroid disease, yielding 85,584 matched comparisons, patients with thyroid disease to have a significantly higher cumulative incidence of uveitis when compared to the control cohort with the Kaplan-Meier analysis. This result was further confirmed by Cox regression analysis. The increased risk was persistent in both genders. The association between thyroid disease and uveitis was stronger in patients without diabetes or hypertension.Conclusion: Patients with thyroid disease were found to have a higher risk for uveitis. For certain age groups or patients without diabetes or hypertension, the role of thyroid disease might be more crucial for uveitis development. [ABSTRACT FROM AUTHOR]

Background: To evaluate the efficacy of micro-incision vitrectomy surgery using a non-contact wide-angle viewing system for fovea-attached type epiretinal membrane, and to report the factors influencing the outcome. Methods: A retrospective, comparative case series that included 50 patients with fovea-attached type epiretinal membrane who received micro-incision vitrectomy surgery using a non-contact wide-angle viewing system. Results: All patients were followed-up for a minimum of 12 months. Seven cases were classified as group 1A (mainly outer retinal thickening), 17 were group 1B (more tenting of outer retina and distorted inner retina), and 26 were group 1C (prominent inner retina thickening and inward tenting of outer retina). Outcome measures included operation time, recurrent rate, postoperative BCVA, and CRT. The mean operative time was 26.2 minutes. The mean change of BCVA (LogMAR) was − 0.43 (p< 0.001). The mean change of CRT was 135.3 μm (p< 0.001). The mean change of CRT was significantly higher in group 1C. Worse preoperative BCVA, male gender, and longer operative time can predict better postoperative BCVA found by multivariate logistic regression and multiple regression models. Conclusion: Significant improvement in BCVA and CRT is noted after micro-incision vitrectomy surgery to operate fovea-attached type epiretinal membranes. Worse preoperative BCVA, male, and longer operation time could predict better improvement. These findings may assist surgeons in better evaluating the potential of this method to help their patients with epiretinal membranes. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the efficacy of microincision vitrectomy surgery (MIVS) for the treatment of post-cataract surgery endophthalmitis, and to report the factors which influence the outcome.Methods: This retrospective case series included eyes with post-cataract surgery endophthalmitis that had received MIVS between June 2014 and May 2017. The anatomical and functional results were analyzed.Results: 24 eyes of 24 patients were included with mean age 72.0 ± 8.6 years old. Best-corrected visual acuity (BCVA) improved in 70.8% of patients with a significant mean logMAR BCVA change of -0.6 ± 0.9. Positive culture rate was 25%. In all study eyes, inflammation became silent after MIVS. In univariate analysis, patients with improved BCVA have shorter duration between cataract surgery and MIVS and less likely to have positive culture results. Using degree of BCVA improvement as a continuous variable, it showed that duration between cataract surgery and MIVS had significantly negative correlation with BCVA improvement. Patients with positive culture results had significantly lower BCVA improvement. Multiple regression models also confirmed the most important outcome-influencing factors.Conclusion: MIVS is an efficient management for post-cataract surgery endophthalmitis. BCVA is significantly improved after MIVS. No matter in univariate or multivariate analysis, positive culture results and longer duration between cataract surgery and MIVS have significant negative effects on the outcome of post-cataract surgery endophthalmitis. Multicenter collaboration should be conducted in order to formulate better management protocols of this vision-threatening complication of cataract surgery. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the effects of dexamethasone intravitreal implant (Ozurdex) and identify risk factors for repeated treatment in patients with macula edema due to branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO).Methods: Patients followed up for at least 6 months were enrolled from 2013 to 2016. Dexamethasone intravitreal implant was given as the baseline treatment. For evaluation of dexamethasone intravitreal implant effects and complications, the demographics, medical history, best-corrected visual acuity (BCVA), intraocular pressure, and central retinal thickness (CRT) were recorded. Multivariate Cox proportional hazard model and logistic regression were used to identify factors for repeated treatment.Results: Twenty-three BRVO and 11 CRVO patients were enrolled. There were 15 males and 19 females. Fifteen (44.12%) patients needed only one dexamethasone intravitreal implant. The peak CRT and BCVA significantly improved. Comparing single-injection with multiple-injection group, age and initial CRT more than 400 μm were significantly higher in the multiple-injection group. From multivariate logistic regression and Cox proportional hazards analysis, patients with age older than 55 years and initial CRT more than 400 μm had higher risk for multiple injections.Conclusions: Patients receiving as-needed schedule of dexamethasone intravitreal implant had significant peak CRT and BCVA improvement. Age older than 55 years and initial CRT more than 400 μm were significant risk factors associated with repeated dexamethasone intravitreal implant treatment. [ABSTRACT FROM AUTHOR]
