A Clinical Study of Central Retinal Vein Occlusion

ABSTRACT

Central retinal vein occlusion(CRVO) is a common retinal vascular disorder with potentially blinding complications. Author evaluated the 21 cases of central vein occlusion in aspects of age, laterality, change of visual acuity, axial length, associated diseases and complications. The results were as follows; 1. The patients were comprised of 8 males and 13 females and the average age was 49.2 +/- 12.5 years. 2. The left eye was affected more than the right eye. 3. The initial visual acuity was below 0.1 in 76.2%. 4. The mean axial length of the aftected eyes(23.03 +/- 0.69mm) was shorter than that of their control group(23.53 +/- 0.69mm) (P=0.01). 5. The most common associated disease was hypertension (33.3%) and the next was diabetes mellitus (9.5%) and arteriosclerosis (9.5%). 6. The most common complication was cystoid macular edema (42.9%). Retinal and disc neovascularization was occmed in 19.4%.
