“…Reported results of patients with confirmed ischemic third nerve palsy show that only 74 to 80% present with normal pupillary function [48][49][50][51] (2a, 1b, 1b, 2b). When incorporating intact pupillary function, the literature has consistently shown that in patients over the age of 50 years with atherosclerotic risk factors, the most likely cause of complete third nerve pupil-sparing palsy is ischemia (followed by trauma and giant cell arteritis) 48,[52][53][54][55] (2a, 1b, 1b, 3a, 3b). When a patient presents with a complete or incomplete pupil involving third nerve palsy, it is essential to rule out an aneurysm 40,48,[56][57][58] (1b, 2a, 2b, 1b, 1b).…”
