作者为研究全视网膜光凝对糖尿病患者虹膜、房角新生血管形成及新生血管性青光眼方面的晚期疗效,于1967～1971年间用红宝石激光治疗184例糖尿病性增殖性视网膜病变患者,选择1只有较晚期视网膜病变眼做治疗,对侧眼不治疗作为对照,至少观察5年。共复查了其中93例。作者应用脉冲红宝石激光器,在检眼镜上有2.5°孔,激射后可形成直径0.75mm脉络膜视网膜光斑。激射量因人而异,使产生1或2强度的光斑。每次光凝200～300点,分布在除视乳头、
The authors studied the late effects of panretinal photocoagulation on the iris, atrioventricular angiogenesis and neovascular glaucoma in diabetic patients. A total of 184 patients with diabetic proliferative retinopathy were treated with ruby laser between 1967 and 1971. Only 1 Retinal eye disease treatment, contralateral eye without treatment as a control, at least observed for 5 years. A total of 93 cases were reviewed. The authors applied a pulsed ruby laser, which had a 2.5 ° hole in the ophthalmoscope and was capable of forming a choroid retinal spot of 0.75 mm in diameter upon lasing. The amount of lasing varies from person to person, resulting in a 1 or 2 intensity spot. Each photocoagulation 200 to 300 points, in addition to optic disc,
