Retinal and choroidal changes in steroid-associated central serous chorioretinopathy

Abstract Background To evaluate the retinal and choroidal alterations in steroid-associated central serous chorioretinopathy (CSC) in comparison to idiopathic CSC. Methods In this retrospective cohort study, swept source optical coherence tomography scans of eyes with steroid-associated CSC (group A) were compared with the same in idiopathic CSC (group B). The key features included central subfield retinal thickness, subfoveal choroidal thickness, subfoveal large choroidal vessel diameter, subretinal deposits, retinal pigment epithelial irregularities, double layer sign, hyperreflective dots, intraretinal fluid, and choroidal vascularity index (ratio of choroidal luminal area and total choroidal area, measured on a high definition horizontal 9 mm OCT B-scan. Results There were 20 eyes in group A and 30 in group B. Group A had a higher female proportion (60 vs. 16.67%; P < 0.01) and higher bilaterality (30 vs. 6.67%; P = 0.03). The height of neurosensory detachment was lower in group A (153.1 ± 175.70 µm vs. 312.9 ± 223.06 µm; P < 0.01). There was no significant difference in the prevalence of subretinal deposits, retinal pigment epithelial irregularities, pigment epithelial detachments, double layer sign, outer retinal layer disruption, and intraretinal fluid. Hyperreflective dots (HRDs) were less common in group A (15 vs. 46.67%; P = 0.03). The subfoveal choroidal thickness (P = 0.65) and subfoveal large choroidal vessel diameter (P = 0.78) were comparable. There was a trend towards a higher choroidal vascularity index (CVI) in group A (A: mean, 82%, 95% CI, 66–99%; B: mean, 58%, 95% CI, 57–59%; P = 0.10). Conclusion Steroid-associated CSC has a marginally higher CVI and less common association with HRDs as compared to idiopathic CSC

Purpose: There is no established therapy for exudative-hemorrhagic complications in primary retinal arteriolar macroaneurysm (RAM)

Gender variation in central serous chorioretinopathy

Background: Comparison of presentation and outcomes of central serous chorioretinopathy (CSC) between male and female subjects in different ethnic populations. Methods: Retrospective comparison between male and female subjects with CSC was completed. Demographic details, clinical presentations, imaging features and treatment outcomes were compared at baseline and at last follow-up. Results: This study included 155 male and 155 female subjects with a mean (CSD) age of 43.8 ± 10.3 and 57.0 ± 12.1 years, respectively, and a mean duration of follow-up of 8.49 ± 12.6 months. At presentation, there was no difference in visual acuity; however, visual acuity was significantly higher for female subjects at last follow-up (p = 0.02). Optical coherence tomography (OCT) analysis showed that subretinal deposits (p < 0.001), hyperreflective foci (p = 0.001), retinal pigment epithelial detachment (p = 0.01) and retinal pigment epithelium (RPE) irregularities (p = 0.03) were higher in male subjects at presentation. Angiographic analysis showed that diffuse leakage and RPE tracts were common in males (p = 0.01 and p = 0.02). No significant differences in choroidal dilatation or diffuse choroidal leakages were noted. Conclusions: Female subjects with CSC appear to have better outcomes, with less chances of diffuse RPE damage and other OCT features compared to males
