RELATION BETWEEN RETINAL VEIN OCCLUSIONS AND AXIAL LENGTH

Aims-To evaluate the ocular axial length as a risk factor for developm ent of central retinal vein occlusion (CRVO) and branch retinal vein o cclusion (BRVO).Methods-Ocular axial lengths were measured, by A-scan ultrasonography, in 17 patients with CRVO and 41 patients with BRVO an d compared with those of contralateral unaffected eyes and 66 age matc hed controls. Results-In 17 patients with CRVO the mean axial length o f affected eyes was 22.25 (SD 0.19) nun and of unaffected eyes was 22. 61 (0.13) nun. In 41 patients with BRVO the mean axial length of affec ted eyes was 22.89 (0.11) mm and of unaffected eyes was 22.99 (0.12) m m. Conclusion-These findings confirm that the axial lengths in CRVO an d BRVO were significantly shorter than in the controls. This significa nt difference may be a risk factor in the development of CRVO and BRVO .
