I have seen a lady in her 60s with an episode of presumed bilateral NAION a couple years ago (negative MR orbits, extensive lab work, CSF) who then had recently had an episode of painless monocular vision loss associated with disc edema documented by an ophthalmologist. By the time I had seen her, the disc edema had resolved, but her acuity and field had worsened compared to prior exams. She had just started a GLP-1 a few months prior. Her work-up was negative and working diagnosis was recurrent NAION in setting of GLP-1, although I had never made the presumptive diagnosis of recurrent NAION prior to that case.
Just an anecdote.
