Abstract:
AIM:To analyze the imageological changes of acute and chronic central serous chorioretinopathy (CSC) by 2 types of optical coherence tomography (OCT). METHODS:A retrospective analysis was performed, inclu-ding data of 60 eyes from 56 patients with CSC diagnosed by conventional eye examination, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA), which were divided into acute group (28 eyes of 28 patients) and chronic group (32 eyes of 28 patients) according to imageological examinations and duration (6 months). Optical coher-ence tomography angiography (OCTA) and spectral domain optical coherence tomography ( SD-OCT) were performed to study the vessel density of the chorioretinal leyers and the integrity of the outer retinal structure. RESULTS:In the pa-tients with chronic CSC, OCTA in 4 eyes ( 12.50% ) revealed the presence of a distinct choroidal neovascularization (CNV), while no evidence of CNV in ICGA was observed. However, no sign of CNV in acute CSC group both on OCTA and ICGA was found. The occurrence of 'dark areas' in chronic CSC was much higher than that in acute CSC ( P <0.01). In addition, the integrity of the outer retinal structure (defined as tissue between external limiting membrane and retinal pigment epithelium) in acute group was significantly better than that in chronic group ( P <0.01). CONCLU-SION:Our study demonstrates the existing secondary CNV that is not demonstrated by ICGA in the chronic CSC patients, and the different characteristics of retinochoroid structures between acute and chronic CSC in OCTA and SD-OCT are ob- served. Chronic CSC has more severe structural changes.
