Abstract：
UNASSIGNED: 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).
UNASSIGNED: 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.
UNASSIGNED: 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).

摘要：
■通过观察并比较由于医源性栓塞或非医源性闭塞引起的眼血管意外（OVA）患者的眼动脉（OA）的形态和功能差异，我们提出了一种基于有创数字减影血管造影（DSA）的OA特征的分类系统。
■所有在2017年1月至2021年12月的OVA后1周内接受眼动脉DSA的患者被纳入，并分为不同类型，并比较医源性栓塞和非医源性闭塞类别之间的差异。
■本研究共纳入27例患者的27只眼。根据颈动脉/颅内动脉DSA的结果，OA伴OVAs的形态和功能异常可分为五种类型。男性比例(7.14%),医源性栓塞类别中的眼缺血综合征（OIS）（0.00％）和新生血管性青光眼（NVG）（0.00％）明显低于（84.62、61.54和69.23％，分别）非医源性闭塞类别（分别为p<0.001，p=0.001，p<0.001）。然而,无光感知(NLP)的比例(100%)，眼前段缺血（ASI）（71.43%），和眼眶受累（眼肌麻痹和上下垂，42.86%)最终发生在前者显著大于后者(23.08,0.00,0.00%,分别）（p<0.001，p<0.001，p=0.010）。
