Branch Retinal Artery Occlusion Following Cocaine Inhalation: Case Report and Review of the Literature.

Cocaine abuse has been reported to cause devastating systemic and ocular side effects. Retinal vascular occlusion following cocaine abuse has been scarcely reported in the literature. Herein, we are describing a rare case of branch retinal artery occlusion (BRAO) following intranasal cocaine use in a young female. She presented to the emergency department 1 month after having blurred vision in the left eye, which started 1 day after cocaine nasal inhalation. Fundus examination of the left eye showed an inferotemporal BRAO. In conclusion, cocaine should be considered in the differential diagnosis of retinal arterial occlusion in young healthy patients.
