Abstract:
Objective:To compare clinical characteristics of acute and chronic central serous chorioretinopathy (CSC).Methods:41 patients with CSC in the First Affiliated Hospital of Soochow University were studied, according to the course, they were divided into acute central serous chorioretinopathy group (A group, 29 eyes of 29 cases) and chronic central serous chorioretinopathy group (B group, 12 eyes of 12 cases). All patients underwent the best corrected visual acuity (BCVA), subretinal fluid thickness (SRF) and subfoveal choroidal thickness (SFCT) examination. The imaging characteristics of fundus fluorescein angiography (FFA) and optical coherence tomography angiography (OCTA) were compared between the two groups.Results:The BCVA, SRF and SFCT in A group were higher than those in B group ( P<0.05). FFA in group A showed that the leakage of ink diffusion or smoke type fluorescein leakage. FFA in group B showed that the fluorescein leakage was single or multiple in macular area, and atrophy of retinal pigment epithelium (RPE) cells was observed. OCTA of group A showed that the choroidal capillary layer showed high blood flow signal, low blood flow signal around the outside, or coarse granular high signal, and no choroidal neovascularization (CNV) was found. OCTA in group B showed that the image of choroidal capillary layer was similar to that of group A, but in group B, 2 eyes (2/12) had CNV with obvious morphology. Conclusions:Clinical characteristics of acute and chronic central serous chorioretinopathy are different. OCTA has definite application value in follow-up and detection of CNV.
