Aim: To evaluate role of axial length in patients with central retinal vein occlusion.
Patients and Methods: Thirty patients with unilateral central retinal vein occlusion (19 ischaemic and 11 non-ischaemic) were enrolled in the study. Twenty nine individuals who matched the study group for age, sex, hypertension, and diabetes mellitus status were enrolled as a control group. Patients with macular oedema were excluded. The axial lengths of the affected and fellow eyes of patients with central retinal vein occlusion and the controls were measured using A-scan ultrasonography.
Results: The mean axial length of the affected eyes was not statistically significantly shorter than the mean axial length of the unaffected fellow eyes in the group with central retinal vein occlusion (22.88 mm and 22.90 mm, respectively). There was no statistically significant difference in mean axial length between the ischaemic and non-ischaemic subgroups and the unaffected eyes. There was no statistically significant difference in mean axial length between the eyes with central retinal vein occlusion and the control eyes (22.88 mm and 23.11 mm, respectively). There was no difference in mean axial length between the ischaemic and non-ischaemic subgroups and the control eyes.
Conclusions: This study did not demonstrate a significantly shorter axial length in eyes with central retinal vein occlusion. Axial length as a measurement of hyperopia may not be a risk factor for central retinal vein occlusion if patients with macular oedema are excluded.
