망막정맥폐쇄의 임상적 분류 및 임상양상

Abstract

Clinical evaluation was performed in 181 eyes of 173 patients with retinal vein occlusion in aspects of disease onset, visual acuity, age and sex distribution, associated systemic disorders, laser treatment and ocular complications. The age of onset ranged from 20 to 82 years old. Seventy five patients were male and 98 were female. Central retinal vein occlusion included 38 eyes(ischemic type; 16 eyes, non-ischemic type; 22 eyes), hemi-central retinal vein occlusion 15 eyes(ischemic type; 5 eyes, non-ischemic type; 10 eyes), and branch retinal vein occlusion 128 eyes(major branch type; 91 eyes, macular branch type: 37 eyes). Hypertension was the most common associated systemic disease for each retinal vein occlusion type. The causes of severe visual loss in retinal vein occlusive diseases were macular edema, anterior and posterior segment neovascularization, and vitreous hemorrhage.
