Abstract: 

Objective: To determine the association between the axial length of the eye and retinal vein occlusion [Branch Retinal Vein Occlusion (BRVO) and Central Retinal Vein Occlusion (CRVO)].
Method: 18 patients with CRVO and Hemi-Retinal Vein Occlusion (hemiRVO) and 18 patient with BRVO were selected and 18 patient who referred for cataract extraction were matched with cases as control group. Axial length was measured in both eyes in cases and controls with A-scan biometry. The data were analysed according to student t test.
Results: The affected and fellow eyes in CRVO group differ significantly in axial length (P=0.007). In BRVO group this difference was less but still significant (P=0.048). The axial length of non affected eye of CRVO and BRVO groups is lower than control group with P=0.047 & P=0.017 respectively. In BRVO group mean axial length of the affected eyes was 22.52 mm (80=0.72) and mean axial length of the fellow eyes was 22.77 mm (80=0.64). In CRVO group mean axial length of the affected eyes was 22.71 mm (80= 0.85) and mean axial length of the fellow eyes was 23.23 mm (80=0.71).In control group mean axial length was 23.77 mm (80=1.02).
Conclusion: In our study the affected eyes in both groups were smaller than the fellow eyes, this difference in CRVO group is more pronounced. However this study could not clarify that this difference is either the cause or the effect of the vein occlusion, on the other hand even the fellow eye in BRVO & CRVO group is smaller in axial length than control eyes.
