自1985年4月我科用国产红宝石激光器治疗视网膜静脉周围炎7眼,效果尚满意,报道如下。本组7例中男性5例,女性2例。年龄14岁～55岁,平均31岁。单眼患病3例,双眼4例,后4例均单眼光凝,共光凝7眼。发病后开始治疗病程最短者2天,最长4年。本组病例诊断的临床依据是:视网膜静脉有白鞘或阻塞,静脉扩张或扭曲,反复眼底出血或玻璃体积血。眼底荧光血管造影发现静脉壁受侵蚀,渗漏、血管闭塞、无灌注区及新生血管形成。治疗时,在病变范围内广泛光凝,对已发生改变的静脉,行包围光凝,对静脉枝及侧枝均给予保护。光凝能量为0.05～0.09焦耳,以(?)级反应为度,每次光凝不超过150击,光斑约200～500μ,光斑间距 Since April 1985, our department with domestic ruby ​​laser treatment of retinal vein around inflammation 7, the effect is still satisfactory, are reported below. The group of 7 patients, 5 males and 2 females. Aged 14 years old to 55 years old, average 31 years old. Monocular disease in 3 cases, 4 eyes, after 4 cases were monocular photocoagulation, a total of 7 cases of photocoagulation. After the onset of treatment for the shortest duration of 2 days, up to 4 years. The clinical diagnosis of this group of patients are based on: retinal vein white sheath or obstruction, vein dilatation or distortion, repeated fundus hemorrhage or vitreous hemorrhage. Fundus fluorescein angiography found that the vein wall by erosion, leakage, vascular occlusion, no perfusion area and neovascularization. Treatment, the extensive photocoagulation within the scope of the lesion, venous changes have taken place, surrounded by photocoagulation, venous branches and collateral are given protection. The photocoagulation energy is 0.05 to 0.09 Joule, and the reaction rate is (?), With each photocoagulation less than 150 shots, the spot size is about 200 ~ 500μ, the spot spacing
