Acute and chronic central serous chorioretinopathy: choroidal changes observed with enhanced depth imaging optical coherence tomography

Abstract

Objective: To analyze and compare changes in choroidal thickness at the foveal level in patients with acute and chronic central serous chorioretinopathy (CSC), based on measurements made with EDI-OCT technology, compared with age-matched controls.
Materials and methods: An observational, retrospective case-control study included patients diagnosed with acute and chronic CSC, evaluated between May 2018 and February 2020 at the Clínica de Ojos Cordoba. A control group of 30 eyes from 30 healthy patients of the same age was included. All patients had measurements of choroidal thickness with EDI-OCT function.
Results: A total of 72 eyes, of which 32 had acute CSC and 40 chronic CSC, were included. The mean choroidal thickness of the eyes with acute and chronic CSC was 356,9 µm (SD = 42,5) and 334,7 µm (SD = 108,1), respectively, while in control eyes it was 253 µm (SD = 28,3). The mean choroidal thicknesses of the eyes with CSC, both acute and chronic, were significantly greater than in the control eyes (p=0,0001), but there were no significant differences among them.
Conclusions: All eyes with CSC, both acute and chronic, present an increase in subfoveal choroidal thickness compared to normal eyes of the same age. EDI-OCT proved to be a useful tool to assess choroidal thickness.
