Yield of Investigations in Young Patients Presenting with Transient Monocular Vision Loss

Transient monocular vision loss (TMVL) in older patients warrants thorough work-up including investigation for potential embolic sources with imaging of the carotid circulation and cardiac evaluation. In young patients with lower risk for atherosclerosis, arrhythmias, and cardiac disease, it is unclear whether the same approach should be used. The objective of the present study was to evaluate the yield of investigations in patients under 45 years old presenting with TMVL. This was a retrospective cohort study of 22 patients with TMVL presenting to a neuroophthalmology clinic. We collected information on demographics, ophthalmic investigations, neuroimaging, cardiac investigations, and laboratory findings.
