目的 :探讨视网膜静脉阻塞范围、分型、并发症与视力损害的关系。方法 :通过眼底检查和眼底荧光血管造影将 2 0 7例 (2 10眼 )视网膜静脉阻塞患者分为二类八型。结果 :2 10眼中低视力最多的阻塞类型是缺血型视网膜分支静脉阻塞 ,共 6 0眼 (2 8.5 7% ) ,其次是非缺血型视网膜分支静脉阻塞 30眼 (14.2 9% ) ,损害视力最严重的并发症是黄斑囊样水肿 ,其次是视网膜新生血管。结论 :本研究表明视网膜分支静脉阻塞 (缺血和非缺血 )发病率高 ,故对视力的损害大于总干阻塞 ,视网膜静脉阻塞最严重的并发症是黄斑囊样水肿。 Objective: To explore the relationship between retinal vein occlusion range, classification, complications and visual impairment. Methods: Twenty-seven patients (210 eyes) with retinal vein occlusion were classified into two types and eight types by fundus examination and fundus fluorescein angiography. Results: Among the 210 eyes, the occlusion type with the most low visual acuity was ischemic retinal branch vein occlusion (60.5%), followed by 30 eyes (14.29%) with nonischemic retinal branch vein occlusion, which impaired the visual acuity The most serious complication is cystoid macular edema, followed by retinal neovascularization. CONCLUSIONS: This study shows that the incidence of retinal branch vein occlusion (ischemia and non-ischemia) is high and thus impairs visual acuity more than total dry obstruction. The most serious complication of retinal vein occlusion is cystoid macular edema.
