Association of systemic diseases with retinal vein occlusive disease.

Retinal vein occlusion (RVO) is the second commonest vascular disease of the eye, second only to Diabetic Retinopathy. The association of the retinal vein occlusion with other systemic disease likes hypertension, diabetes mellitus and others has been well documented. With the increase in persons being affected from these disorders, patients with retinal vein obstruction are also increasing. Hence, a study was designed to evaluate all cases of RVO to find out its association with systemic disorders. A total of 100 patients (106 eyes) were enrolled in the study. Out of which, 66 cases reported to have Brach Retinal Vein Occlusion (BRVO) and rest 34 cases with Central Retinal Vein Occlusion (CRVO). Among the associated systemic diseases, hypertension and diabetes mellitus accounted for 84% cases. Isolated hypertension (54%) was most commonly seen followed by diabetes mellitus (8%). The prevalence of BRVO was almost twice as compared to CRVO. The high association of various systemic disorder especially Hypertension and diabetes further supports the need of early and periodic eye examination for those suffering from these disorders.
