ABSTRACT=Background: 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). 
Methods: 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.
Results: 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 (P <0.001, P =0.001, P <0.001, respectively). However, the proportion of no light perception (NLP) (100%), anterior segment ischemia (ASI) (71.43%), and orbital involvement (ophthalmoplegia and ptosis, 42.86%) eventually occurring in the former was significantly greater than that in the latter (23.08%, 0.00%, 0.00%, respectively) (P <0.001, P <0.001, P =0.010, respectively).
Conclusion: Ocular vascular accidents can be divided into five types based on the characteristics of OA on DSA.
