Purpose To evaluated the changes in choroidal vasculature patients with ocular ischemic syndrome (OIS) and ipsilateral eyes of symptomatic carotid artery stenosis (CAS) Method A total 50 (15 OIS, 10 CAS, 25 age-and sex-matched control group) were included, medical records retrospectively reviewed. The mean subfoveal thickness (SFCT) each eye was measured, binary images choroid to compare area luminal area. Results SFCT 170.5±75.3 μm 154.8±62.9 277.5±73.2 right group (P<0.001). 494,478.6±181,846.2 μm2 453,750.0±196,725.8 720,520±281,319.5 (P = 0.036). 333,185.7±112,665.9 313,983.3±132,032.1 480,325.0±185,112.6 0.046). SFCT, area, significantly smaller OIS 0.017, P 0.005, 0.004, respectively), those CAS 0.020, 0.016, 0.021, respectively) than unaffected contralateral eyes. There no significant differences between 0.984, 284, 0.413, respectively). Conclusion thinner compared had Choroid may reflect vascular status artery, indicated by thinning decreasing especially
