Axial length and hyperopia in eyes with retinal vein occlusions.

Abstract

We performed a prospective study in order to elucidate the predisposing role of axial length and hyperopia in retinal vein occlusions. The study group comprised 39 patients with unilateral central retinal vein occlusion (CRVO), 50 patients with unilateral branch retinal vein occlusion (BRVO), 13 patients with unilateral hemispheric retinal vein occlusion (HRVO) and 45 control eyes. The axial length of affected eyes was compared to fellow eyes and control eyes in each subgroup of patients with retinal vein occlusion. No statistical difference was noted for any of the subgroups (p > 0.05). Hyperopia was detected in 12 of 39 eyes (31%) with CRVO, 14 of 50 eyes (28%) with BRVO, 4 of 13 eyes (31%) with HRVO and 15 of 45 eyes (33%) in the control group. No statistically significant difference was discovered (p > 0.05). In the light of our study, we believe that axial length and hyperopia may not be risk factors in retinal vein occlusions, in contrast to common belief.
