Abstract

To determine the relation between retinal microstructural changes and the response to 577-nm subthreshold micropulse laser (SML) treatment in chronic central serous chorioretinopathy (cCSC). This retrospective study included 39 eyes of 39 patients with cCSC, treated with the 577-nm SML. The eyes were evaluated in three groups: complete remission, partial remission, and failure groups. The presence of some baseline retinal microstructural changes, thickness of the outer nuclear layer (ONL), status of the ellipsoid zone (EZ), and retinal pigment epithelium (RPE) were evaluated. The changes in central macular thickness (CMT), subretinal fluid (SRF) height, and best-corrected visual acuity (BCVA) were calculated. There were 14, 13, and 12 eyes in the complete remission, partial remission, and failure group, respectively. The baseline EZ and RPE were found intact in 71.4% and 64.3% of the eyes in the complete remission group, respectively; however, these rates were respectively 25% and 16.7% in the failure group (p < 0.05). Extrafoveal foci were present in 35.7% of the eyes in the complete remission group, but none was found in the failure group (p < 0.05). Although there was no statistically significant difference, the baseline ONL thickness was higher, and the hyperreflective dots, retinal bumps, subretinal fibrinous exudates, and PEDs were seen less in the complete remission group. The changes of the BCVA were not significant in any of the groups at the last visit (p > 0.05). The presence of baseline intact EZ and RPE, and extrafoveal foci can potentially be used as predictors of the SML treatment success in cCSC.
