Abstract

Branch retinal vein occlusion (BRVO) is the second most common form of retinal vascular diseases next to diabetic retinopathy. Several risk factors such as hypertension, diabetes mellitus, and hyperopia have been shown to be associated with BRVO. The pathogenesis of branch retinal vein occlusion has not been well understood. This study was conducted prospectively on 21 patients with BRVO and normal 21 patients as controls to assess the relationship of the axial length with the development of BRVO. Mean axial lengths of the affected and the fellow eyes in the branch retinal vein occlusion group were 22.69 +/-0.72 mmand 22.89 +/-0.67mm, respectively. The difference between mean axial lengths of the affected and the fellow eyes was not statistically significant (p=0.17). The mean axial length of control eyes was 23.22 +/-1.29 mm. The affected eyes in the BRVO group were 0.53 mmshorter than eyes in control group on the average, and the difference was statistically significant(p=0.04). This study suggests that shorter axial length could be a local risk factor in the pathogenesis of branch retinal vein occlusion.
