Retinal Artery Occlusion in Young Patients: A 6-Year Review

Abstract

Purpose: This article describes the characteristics, management, and etiology of retinal artery occlusions (RAOs) in young patients. Methods: 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. Results: 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. Conclusion: 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.
