Purpose: To investigate the risk factors for patients with focal choroidal excavation (FCE) and their correlation with chorioretinal diseases. Design: Retrospective cross-sectional study. Subjects: Patients with FCE were enrolled, while healthy subjects were recruited for the control group. Methods: The study collected demographic information, clinical features, and multimodal images. Parameters of FCE identified using spectral-domain OCT (SD-OCT) were manually measured using built-in software and subsequently analyzed statistically. Main Outcome Measures: Subfoveal choroidal thickness (SFCT), subexcavation choroidal thickness (SECT), and the greatest depth and width of each excavation were manually measured using built-in calipers in OCT software. Results: Twenty-one patients (13/8, male/female) with FCE were included in this study. The average age was 45.2 years, and their best-corrected visual acuity (BCVA) was 0.4 logarithm of the minimum angle of resolution (Snellen equivalent, 20/50). Focal choroidal excavation was present in 28 eyes of 21 patients, including isolated FCE (12 eyes) and complicated FCE (16 eyes) with choroidal neovascularization (sCNV), central serous chorioretinopathy, and other conditions. Patients with complicated FCE were significantly older than those isolated FCE (P = 0.015). The SFCT of the healthy subjects was significantly less than that of the fellow eyes of the patients with FCE (P
