Detection of Choroidal Neovascularization in Central Serous Chorioretinopathy Using Optical Coherence Tomographic Angiography

Abstract

Purpose: To demonstrate the detection of choroidal neovascularization (CNV) in clinically diagnosed central serous chorioretinopathy (CSC) by optical coherence tomographic angiography (OCTA). Methods: Seventy-five eyes of 70 patients were included. OCTA was performed on each patient. Two trained readers evaluated the images independently to confirm the diagnosis and identify CNV at the level of the outer retina. Results: All studied eyes presented characteristics consistent with CSC based on eye examination and traditional imaging technologies, including fundus fluorescein angiography, which showed no evidence of CNV. However, OCTA revealed definite abnormal vascularization at the level of the outer retina in 8 eyes (10.7%) of 8 patients (11.4%). Conclusion: This study suggests that in some cases of CSC, OCTA could be an alternative option to detect CNV that is undetectable by other conventional imaging techniques.
