Subijay Sinha

Purpose: To assess risk factors for central retinal vein occlusion (CRVO) associated morbidity and mortality in Indian population.

Methods: Participants included patients with CRVO 40 years and younger. Predisposing factors and systemic complications were examined.

Results: Unilateral (n = 14) and bilateral (n = 1) CRVO were studied with mean follow-up time of 12 months. Hyperhomocysteinemia (80%), hypercholesterolemia (65%), and hypertriglyceridemia (64%) were identified as risk factors. 2 (14%) developed stroke and 1 (7%) developed transient ischemic attack during the follow up. Macular edema was the most common cause for vision loss (35%). Other less common causes being secondary glaucoma and optic atrophy.

Conclusion: Young Indian patients with CRVO may develop serious complications like stroke. CRVO may serve as initial clinical presentation of serious systemic diseases
