A man in his 40s presented with central vision loss in his right eye of 1-week duration. There were no associated feelings of pain, flashes, or floaters. A review of his systems was significant for bilateral lower leg swelling, a rash of the torso, painful “bumps” on his neck, reduced hearing abilities, and tinnitus.
His medical history was significant for human immunodeficiency virus, controlled with antiretroviral therapy (Strilbild; Gilead Sciences Inc). His cluster of differentiation 4 count was 600, and his viral load was undetectable. His ocular history was unremarkable. He was homosexual, did not smoke, and denied intravenous drug use.
