A Clinical Study on the Occlusion of the Retinal Vein

• Cho KR

Abstract

In general, occlusion of the retinal vein causes marked dlminished visual acuity and poor recovery in elderly persons. Author studied 59 cases of occlusion of retinal vein in the views of sexual and age distribution, laterality, early and later visual acuity, combined systemic and ocular diseases, complications, treatment, and especially findings of fundus fluorescein angiography. The results were as follows: 1. There was no statistical significance in the difference of sexual and age distribution, and laterality of affected eye. 2. The incidence of central retinal vein occlusion is 2.3 times of that of branch retinal vein occlusion. And 78% of all branch retinal vein occulusion affected in superotemporal branch, and remainders in inferotemporal branch. In one case the occlusion had occured at superotemporal and superonasal branch. 3. The early and later visual acuity was poor in central retinal vein occlusion, inferotemporal branch vein occlusion, and superotemporal branch vein occlusion in order. 4. The improvement of visual acuity more than one line in test chart was 52.5% on the average; central retinal vein occlusion(27.8%), inferotemporal branch vein occlusion (55.5%), and superotemporal branch vein occlusion(65.6%). 5. The combined systemic diseases were hypertension, arteriosclerosis, diabetes mellitus etc, and the occular diseases were open-angle glancama and iritis. 6. The causes of poor visual acuity were cystoid macular edema, vitreous hemorrhage, optic nerve damage, complicated neovascular glaucoma, and preexisting open-angle glaucoma. 7. The fundus fluorescein angiography showed delayed filling time, marked dilatation and engorgement of affected vein, dye leakage from affected vein or radial peripapillary capillaries, capillaries, capillary nonperfusion, microaneurysms, cystoid macular edema, collateral circulation, and retinal neovascularization.
