ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY CAN IMPROVE DIABETIC RETINOPATHY SCORE WITHOUT CHANGE IN RETINAL PERFUSION.

PURPOSE: To compare the changes in retinal perfusion on ultra-wide-field fluorescein angiography with the changes in diabetic retinopathy lesions observed on ultra-wide-field fundus color photographs after 3 monthly anti-vascular endothelial growth factor injections. METHODS: Retrospective interventional cohort study analyzing the files of 14 patients with DR (18 eyes). UWF color photos and FA were analyzed at baseline (M0) and 1 month after the third anti-VEGF injection (M3). The main outcomes included the count of the number of red dots (microaneurysms, hemorrhages) and assessment of DR severity score (DRSS); the analysis of non-perfusion areas and disappearance or reappearance of arterioles or venules in the non-perfusion areas on FA. RESULTS: Eighteen eyes of 14 diabetic patients, with mean age of 63 ± 5 years, were included. The DRSS score improved by at least one stage in 11/18 (61%) eyes. The mean number of red dots significantly decreased at M3 (n = 80 ± 85) compared with M0 (n = 139 ± 130) (P < 0.0001). No reperfusion of arterioles or venules was observed in or around nonperfusion areas. CONCLUSION: After anti-vascular endothelial growth factor injections, the improvement in the DRSS score based on color fundus photographs can occur without retinal reperfusion on ultra-wide-field fluorescein angiography.

Predictive Factors of Response to Mineralocorticoid Receptor Antagonists in Nonresolving Central Serous Chorioretinopathy.

PURPOSE: To assess the efficacy and safety of mineralocorticoid receptor antagonists (MRAs) in the treatment of nonresolving central serous chorioretinopathy (CSC) and to identify factors that are predictive of treatment response. DESIGN: Retrospective, multicenter, noncomparative, interventional case series. METHODS: Clinical and imaging data from consecutive patients with nonresolving CSC treated with eplerenone or spironolactone for 3 to 6 months between 2012 and 2016 were reviewed. Outcome measures included the resolution of foveal subretinal detachment (SRD), changes in SRD height, central macular thickness, subfoveal choroidal thickness, best corrected visual acuity, and the occurrence of adverse events assessed at 3 and 6 months. The response to treatment was defined by a decrease by >50% in SRD height under treatment. Comparisons between responder and nonresponder groups were performed using univariate and multivariate regression analyses to identify factors that were predictive of treatment response. RESULTS: Fifty-nine patients (64 eyes) were included. The mean SRD height and central macular thickness significantly decreased while the mean best corrected visual acuity significantly improved at 3 and 6 months. The mean subfoveal choroidal thickness significantly decreased at 3 months. Among the 64 eyes included, 67.2% responded to treatment, among which 38.3% and 40.5% had a complete resolution of the foveal SRD at 3 and 6 months, respectively. Baseline subfoveal choroidal thickness was the only factor associated with a treatment response in the multivariate analysis. CONCLUSION: Our study suggests that MRA could be a safe and effective treatment in patients with nonresolving CSC. MRA treatment is more effective in cases with a thicker baseline choroid.

Shift Work: A Risk Factor for Central Serous Chorioretinopathy.

PURPOSE: To investigate if shift work or sleep disturbances are risk factors for central serous chorioretinopathy (CSCR). DESIGN: Prospective case-control study. METHODS: Forty patients with active CSCR and 40 controls (age- and sex-matched) were prospectively recruited from the Ophthalmology Department of Hôtel Dieu Hospital, Paris, between November 2013 and December 2014. All patients were asked to complete a questionnaire addressing previously described risk factors and working hours, as well as the Insomnia Severity Index (ISI), a validated instrument for assessing sleep disturbances. RESULTS: The mean age of the CSCR group was 44 ± 9 years, whereas the mean age of the control group was 43 ± 10 years. By use of multivariate analysis, shift work (odds ratio [OR] [95% confidence interval]: 5 [1.2-20.4]; P = .02), steroid use (OR: 5.5 [1.1-26.2]; P = .03), and recent psychological stress (OR: 15.3 [4.1-54.5]; P < .001) were found to be independently associated with CSCR. CONCLUSION: The outcomes of this study suggest that shift work is an independent risk factor of CSCR. Further studies are required to confirm these results and to examine if work reconversion would be beneficial in the treatment of patients with chronic/recurrent CSCR.
