Abstract

Central retinal vein occlusion (CRVO) is a common retinal vascular disorder, and it has been suggested to occur by the occlusion of the sclerotic central retinal vein by thrombo- sis in the lamina cribrosa. Various systemic and local conditions have been considered to be predisposing factors to the development of CRVO, and it has been reported that CRVO occurs more frequently in hypermetropic small eyes. We studied on several factors such as age, refractive error, axial length and the association with systemic diseases in 32 eyes of unilateral CRVO. In the CRVO group,the mean axial length of the affected eyes was 23.13 +/-0.99 mm in males and 22.64 +/-0.63 mm in females. That of the unaffected eyes was 23.36 +/-1.17 mm in males and 22.64 +/-0.53 mm in females, the differences were statistically insignificant in males and females (p=0.250,p=0.496). The mean axial length of normal comparison eyes was 23.81 +/-0.73 mm in males and 23.07 +/-0.69 mm in females. The differences between the mean axial lengths of both eyes with unilateral CRVO and that of normal comparison eyes were statistically significant in males and females (p<0.05). In conclusion,the short axial length may play as an important related factor in the development of CRVO.
