摘　　要：目的　分析半侧视网膜静脉阻塞 (hemi retinalveinocclusion ,HRVO)患者与无视网膜血管病变者静脉分支进入视乳头的特点。方法　对 47例 (4 8只眼 )半侧视网膜静脉阻塞患者经眼底彩色照相、荧光素眼底血管造影、 90D前置镜和检眼镜观察视网膜中央静脉进入视乳头的分支情况、眼底改变和视力预后 ,并与 2 6例 (30只眼 )无视网膜血管病变眼正常眼静脉分支进入视乳头的情况进行比较。结果　①患者组和正常组中静脉进入视乳头的分支为 1支者分别为7 1 %和 33 3% (P <0 0 5 ) ;2分支者分别为 67 9%和 5 0 0 % (P >0 0 5 ) ;3分支者分别为2 5 0 %和 1 6 7% (P >0 0 5 )。②阻塞部位 :上半侧支阻塞者 2 1只眼 (4 3 8% ) ;下半侧支阻塞者2 6只眼 (5 4 1 % ) ;对角线型阻塞者 1只眼 (2 1 % )。其中缺血型 2 1只眼 (4 3 8% ) ,非缺血型1 9只眼 (39 6% ) ;8只眼记录不详 (1 6 6% )。③视力预后 :对 40例 (4 0只眼 )半侧视网膜静脉阻塞患者经过平均 7个月的随访观察 ,初诊时为 0 2或 0 2以上者由 2 6只眼 (65 0 % )增加至随访结束时的 34只眼 (85 0 % ) ,其中视力达到 0 5或 0 5以上者由 1 1只眼 (2 7 5 % )增加至 1 7只眼 (4 2 5 % )。④并发症 :48只眼中发生黄斑囊样水肿者 1 9只眼 (39 6% ) ,视网膜?OBJECTIVE To study Characteristic of optic disk vein branch in the patients with hemi retinal vein occlusion (HRVO) and normal retinal vessels METHODS Retinal vein branch of optic disc, fundus condition and prognosis of the visual acuity were observed and with color photograph, fundus fluorescein angiography, and 90D Hruby and slit lamp in forty seven patients (48 eyes) The data of the patients were compared with normal retinal vessels of 26 cases (30 eyes) RESULTS (1)The percentage of one branch was 7 1% in the patients with HRVO and 33 3% in the normal retinal vessels ( P <0 05 ); there were 67 9% and 50 0%( P >0 05),25 0% and 16 7%( P >0 05) respectively in two branches and three branches (2) Position of occlusion: there were 21 eyes (43 8%) in the superior branch occlusion of retinal vein; 26 eyes (54 1%) in the inferior branch; and 1 eye (2 1%) was diagonal position The were 21 eyes (43 8%) were ischemic and 19 eyes (39 6%) were nonischemic in those eyes, and the recorded of 8 eyes (16 6%) were not detailed (3) The prognosis of visual acuity: The follow up time was average of 7 months in 40 patients with HRVO The initial visual acuity 0 2 or more were 26 eyes (65 0%),and 34 eyes ( 85 0%) last number of for the visual acuity 0 5 or more eyes was increased from 11 eyes (2 7 5%) to 17 eyes (42 5%) among them in the follow up period (4)Complications: The macular cystoid edema were 19 eyes (39 6%), and retinal neovascularization 7 eyes (14 6%) including optic disk neovascularization 2 eyes (4 2%) among 48 eyes One eye (2 1%)was only optic disk neovascularization CONCLUSION When the retinal vein branches in optic disc vein were two the ratio of HRVO was higher The prognosis of visual acuity and complications is milder than central retinal vein occlusion, and more serious than branch retinal vein occlusion
