This study aimed to train and validate deep learning systems (DLS) to differentiate between microvascular ischemic ocular motor nerve palsy (v-OMNP) and inflammatory ocular motor nerve palsy (i-OMNP). The method involves using clearly diagnosed v-OMNP and i-OMNP patients from the Department of Neurology database at Beijing Tongren Hospital for further DLS validation, aiding in the differential diagnosis of the aforementioned diseases.
