Abstract

Purpose
To evaluate the association of biometric indices with central retinal vein occlusion (CRVO). Methods: The study group consisted of 20 patients with unilateral CRVO. The mean keratometry (mean K), anterior chamber depth (ACD), vitreous length (VL), lens thickness (LT) and axial length (AL) were measured in both eyes. Results: The anterior chamber depth and vitreous length of affected eyes were significantly shorter than those of unaffected eyes in the CRVO group (p=0.01, p=0.002). The lenses of affected eyes were significantly thicker than those of unaffected eyes (p=0.012). Although affected eyes had higher mean keratometry and shorter axial length, the differences were not significant (p＞0.05). Conclusions: Anterior chamber depth and vitreous length of eyes with CRVO may be shorter than unaffected eyes. And lens of eyes with CRVO may be thicker than unaffected eyes. The causal relationship between shallow anterior chamber and CRVO is not clear. So, further studies are needed. Short vitreous length and thick lens may predispose them to more crowding of central retinal vein and artery in lamina cribrosa, and developing CRVO. (Korean J Optom Vis Sci 2011;10(2):78-81)
