Abstract

Objective: To quantitatively assess the changes of subfoveal choroidal thickness (SFCT) and superficial retinal vessel density (%SRVD) in acute and chronic central serous chorioretinopathy (CSC) patients using Spectral Domain Optical Coherence Tomography (SD-OCT) and Optical Coherence Tomography Angiography (OCT A). Method: Cross-sectional, case-control study on 40 CSC patients in Ho Chi Minh City Eye Hospital from April 2022 to October 2022. Result: A total of 40 subjects (80 eyes) were included in this study, with 33 eyes in acute CSC, 7 eyes in chronic CSC, and 40 eyes in control groups. The mean age was 41,4±1,62 years (ranging from 31 to 45 years). The proportions of male and female patients were 72,5% and 27,5% respectively. The major symptom was reduced vision, and the mean BCVA is 0,33 ± 0,07 logMAR. Mean SFCT of CSC eyes was 367,6 ±19,0 μm, which is 302,0±16,6 μm in controls (p<0,05). Mean %SRVD of chronic CSC, acute CSC and controls were recorded and calculated for each regions. Conclusions: In SD-OCT and 6x6-mm OCT A images, varied SFCT and %SRVD were observed in CSC patients and SFCT was found to be changed statistically significant. In the near future, SD-OCT and OCTA could serve as a reliable tool to evaluate different courses of CSC quantitively.
