Abstract

Purpose: To detect changes in deep choroidal vasculature following resolution of central serous choroiopathy (CSC) using Enface swept source optical coherence tomography (SSOCT).

Methods: 9 eyes with CSC were studied during the acute phase and following resolution. Swept source OCT-A scans were obtained and deep choroidal layer was segmented between 150 to 300 microns below RPE. The dilated deep choroidal vessels corresponding to the leak of fluorescein angiography was localized and the area and width of the vessel was compared using imageJ software. Results: Mean age of patients was 41.22±7.45 years. On comparing the area and width of the corresponding dilated vessels before and after resolution of CSC, significant decrease in width (0.89±0.48mm vs 0.662±0.27mm) and area (0.81±0.61mm2 vs 0.56±0.46mm2) was noted post resolution of CSC. Conclusion: Enface SSOCT scans can be used to identify anatomical changes in deep choroidal vessels and help monitor the response of treatment in CSC.
