RESUMEN
BACKGROUND/PURPOSE: Branch retinal artery occlusions (BRAO) are primarily associated with the aging population and are rare in young adults. The etiology of BRAO includes embolic or nonembolic sources. Lisdexamfetamine has been associated with vasospastic ischemic events in multiple areas of the body. However, there are currently no reported cases of BRAO associated with lisdexamfetamine use. Here, we present a case that suggests a correlation between lisdexamfetamine use and a nonembolic BRAO in a young adult man. METHODS/RESULTS: A 32-year-old man presented with sudden left eye blurred vision 17 days after beginning lisdexamfetamine. Fundus examination confirmed the BRAO diagnosis. Following evaluation by a retina specialist, vasospasm was considered the most likely cause for the BRAO. Other possible etiologies were unlikely due to diagnostic testing. CONCLUSION: The temporal association between lisdexamfetamine and BRAO symptom onset suggests vasospastic occlusion. Lisdexamfetamine-associated adverse events should be considered as a possible etiology for BRAO.
