Abstract:

This article describes the characteristics, management, and etiology of retinal artery occlusions (RAOs) in young patients. A retrospective chart review of patients <50 years of age with ophthalmic and RAOs was conducted. Data were collected on demographics, clinical presentation, laboratory and imaging evaluation, management, and outcome. Seventeen eyes of 15 patients younger than 50 (mean age, 34±8 years; 71% male, 29% female) with RAOs were identified. AOs included: 8 (47%) central RAOs (CRAOs), 5 (29%) branch RAOs (BRAOs), 3 (18%) ophthalmic AOs (OAOs), and 1 (6%) combined CRAO and vein occlusion (CRAO/CRVO). Logarithm of the minimum angle of resolution visual acuity (VA) at presentation was 2.6±4 (Snellen range 20/15 to no light perception). Systemic diseases in patients with BRAO included Susac disease (n = 1), sickle cell disease (n = 2), patent foramen ovale (PFO) (n = 1), and HIV (n = 1). CRAO was diagnosed in 4 patients after invasive surgery (3 after neurosurgery and 1 after cardiac surgery). Other patients had hypertension (n = 3), hypercoagulability due to uterine cancer (n = 1), and PFO (n = 1). OAOs were noted in 1 patient with Saturday night retinopathy and in 1 with ruptured internal carotid aneurysm at the level of the ophthalmic artery. Two eyes with CRAO were treated with tissue plasminogen activator (1 intraophthalmic artery through catheterization and 1 intravenously) without any change in final VA. In these patients, VA remained poor (VA hand motions – counting fingers) at 6 months or greater follow-up visits. RAO in young patients is uncommon. In this series, one-fourth of occlusions were seen during the perioperative period. A significant number of patients had concurrent uncontrolled hypertension. Other associated systemic findings included PFO, hypercoagulability, sickle cell disease, Susac disease, and HIV
