By observing and comparing the morphological and functional differences of the ophthalmic artery (OA) in patients with ocular vascular accidents (OVAs) due to iatrogenic embolism or non-iatrogenic occlusion, we propose a classification system based on the characteristics of OA on invasive digital subtraction angiography (DSA). All patients undergoing ophthalmic arterial DSA within 1 week after the OVAs between January 2017 and December 2021 were enrolled and divided into different types, and the differences between iatrogenic embolism and non-iatrogenic occlusion categories were compared. A total of 27 eyes of 27 patients were included in this study. Based on the results of carotid/intracranial arterial DSA, the morphological and functional abnormalities of OA with OVAs can be divided into five types. The proportion of males (7.14%), ocular ischemic syndrome (OIS) (0.00%) and neovascular glaucoma (NVG) (0.00%) in the iatrogenic embolism category was significantly lower than that (84.62, 61.54, and 69.23%, respectively) of the non-iatrogenic occlusion category (
