²Dokuz Eylül Üniversitesi Tıp Fakültesi, İZMİR We performed a prospective study to evaluate the role of axial length and hypermetropia as a risk factor in retinal vein occlusions. Thirty nine patients with central retinal vein occlusion (CRVO), 50 patients with branch retinal vein occlusion (BRVO), 13 patients with hemispheric retinal vein occlusion (HRVO) and 45 control patients were enrolled the study.
Mean values of axial length measurement in CRVO group compared with their normal eyes were 23.20±1.16 and 23.13±1.14, respectively. These values were 23.13±1.0 and 23.15±1.02 in BRVO, 23.29±0.77 and 23.14±0.61 in HRVO and 23.10±.0.63 in the control group. Statistically significant difference between all subgroups of retinal vein occlusion and control group was not detected. (p>0.05)
Hypermetropia was found 31% (12/39) in CRVO, %28 (14/50) in BRVO, 31% (4/13) in HRVO and 33.4% (15.45) in control group. There was no statistically significant difference between groups. (p>0.05)
In light of our study, we concluded that axial length and hypermetropia were not significant risk factors in the ethiology of retinal vein occlusion. Keywords : Diabetes Mellitus Type I, Diabetic Retinopathy, Class I HLA and Class II HLA
