Abstract
The Eye Disease Case-Control Study was a clinic-based, case-control study that investigated risk factors for 5 retinal diseases—branch retinal vein occlusion (BRVO), central retinal vein occlusion (CRVO), neovascular age-related macular degeneration (AMD), idiopathic macular hole, and rhegmatogenous retinal detachment—using a similar protocol and the same large pool of controls. An increased risk of BRVO was found in persons with a history of systemic hypertension, cardiovascular disease, increased body mass index at 20 years of age, a history of glaucoma, and higher serum levels of alpha 2 globulin. An increased risk of CRVO was found in persons with systemic hypertension, diabetes mellitus, and open-angle glaucoma. The authors recommended that patients with BRVO and CRVO should be evaluated for risk factors for cardiovascular disease (hypertension, hyperlipidemia, and diabetes), as well as for open-angle glaucoma.
