Current concepts in managing retinal vein occlusion in young patients.

Retinal vein occlusions (central, hemicentral, and branch retinal veins) are among the most common retinal vascular disorders and account for a significant amount of ocular morbidity. These conditions typically affect older individuals, with most studies reporting the majority of retinal vein occlusions in adults over 60 years of age.1-8 A minority of patients, around 10% to 15%, are typically younger than 50 years of age, representing a significant number of working-aged adults. Up to 16% of all instances of central retinal vein occlusion (CRVO), 10% of all hemicentral retinal vein occlusion (HRVO), and 1% to 5% of all branch retinal vein occlusion (BRVO) occur in younger patients.9-12 Vision loss in BRVO (Figure 1) is generally secondary to macular edema and in CRVO (Figure 3) may be from a combination of macular edema, macular ischemia, vitreous hemorrhage, and neovascular glaucoma. Younger patients with retinal venous occlusive disease generally fair better visually than their older counterparts. This is particularly true among young CRVO patients, where the majority have less ischemia compared to older CRVO patients.12,13 Current concepts in managing retinal vein occlusion in young patients
