Hayreh calssified central retinal vein occlusion(CRVO) into 2 groups as venous stasis retinopathy(VSR) and hemorrhagic retinopathy(HR) based on pathogenesis. VSR is a benign, nonischemic, and self-limited condition, while HR is a severe, ischemic, and potentially blinding disorder. This classification is beneficial to regarding the prognosis and management of CRVO. The author evaluated the clinical course of 69 cases of CRVO at the Department of Ophthalmology, Paik Hospital, Inje college from January, 1981 to June, 1986. The results were as follows; 1. Among the 69 patients of CRVO, 38 patients were classified as VSR(55.1%) and 31 patients as HR(44.9%). 2. The patients were comprised of 33 males and 36 females. The average age was 52.4 +/- 9.7 years in VSR, and 52.7 +/- 10.1 years in HR. 3. The mean interval between onset of symptom and first ophthalmic consultation was 22 days in VSR, and 8 days in HR. 4. The improvement of visual acuity more than 1 line in test chart was 39.5% in VSR, and 12.9% in HR. 5. The most common associated systemic disease was hypertension(42.0%) and the next was diabetes mellitus(8.7%). Open angle glaucoma was associated in 6 patients(8.7%). 6. Photocoagulation was given 3 cases of VSR and 8 cases of HR. Of the 23 untreated cases with HR, 26.1% developed neovascular glaucoma and none of the 8 cases with HR treated with panretinal photocoagulation developed neovascular glaucoma. 7. Cystoid macular edema was occurred in 39.5% of VSR and 54.8% of HR. Proliferative retinopathy and vitreous hemorrhage were occurred in 1 and 2 cases of HR respectively. |
