Aim: To determine the association between the axial length of the eye and retinal vein occlusion (branch retinal vein occlusion and central retinal vein occlusion).
Patients and Methods: Eighteen patients with central retinal vein occlusion and hemi-retinal vein occlusion and 18 patients with branch retinal vein occlusion were enrolled in this study. Eighteen patients who were referred for cataract extraction were enrolled as a control group. Axial length was measured in both eyes using A-scan biometry. The data were analysed using the Student t test.
Results: The axial length differed significantly between affected and fellow eyes in the central retinal vein occlusion group. This difference was less in the branch retinal vein occlusion group but was still significant. The axial length of the non-affected eyes of both the central retinal vein occlusion and the branch retinal vein occlusion groups was less than the axial length of eyes of the control group. In the branch retinal vein occlusion group, the mean axial length of the affected eyes was 22.52 mm and that of the fellow eyes was 22.77 mm. In the central retinal vein occlusion group, the mean axial length of the affected eyes was 22.71 mm and that of the fellow eyes was 23.23 mm. In the control group, the mean axial length was 23.77 mm.
Conclusions: The affected eyes in both groups of retinal vein occlusion had a smaller mean axial length than the fellow eyes, and the fellow eyes of patients with retinal vein occlusion had a smaller mean axial length than the control eyes. Short axial length may be a local risk factor for retinal vein occlusion.
