ABSTRACT
PURPOSE:
It is unclear whether transient monocular vision loss (TMVL) warrants the same thorough systemic evaluation for potential embolic sources in young adults as it does in older adults. The objective of the present study was to evaluate the yield of investigations in patients under 45 years of age presenting with TMVL.DESIGN:
Prospective cohort study.METHODS:
Young adult patients with TMVL presenting to a university-affiliated neuro-ophthalmology clinic were included. All included patients were referred for neuroimaging (computed tomography or magnetic resonance angiography of entire carotid tree and magnetic resonance imaging of the brain) and cardiac investigations (transesophageal echocardiography and 2 weeks of Holter monitoring).RESULTS:
A total of 20 participants with TMVL were included in the study. The mean age was 33.1 ± 8.2 years, and 16 of the 20 participants were women. The most common finding on past medical history was migraines, in 5 of 20 cases (25%), and 25% of patients had headaches during their visual loss. Of 17 participants who completed neuroimaging, 1 had fibromuscular dysplasia (this patient also experienced headaches during their symptoms). Two of 13 patients who completed echocardiography had patent foramen ovale. Overall, 3 of 20 participants (15%, 95% CI 3%-38%) had abnormal findings associated with their TMVL. Aspirin treatment was initiated in 2 of 3 patients following investigations.CONCLUSION:
In our cohort of young patients presenting with TMVL, 15% of patients had abnormal findings on further investigations. We recommend that young patients presenting with TMVL be referred for neuroimaging and cardiac workup so that appropriate treatments can be initiated to prevent future complications. Headaches during vision loss may not always indicate a benign cause, and retinal migraine should be a diagnosis of exclusion.
