全视网膜光凝治疗糖尿病性增殖性视网膜病变业已表明能有效地减少患者视力严重下降的发生率。然而,激光光凝并不能消除视力下降的可能性,尤其在糖尿病性视网膜病变的“危象”眼。此外,在相当一部分的眼中,其中心视力的损害与激光光凝的副作用有关。本文作者回顾性地复习了全视网膜光凝治疗糖尿病性增殖性视网膜病变病人的眼底所见、眼底照像和荧光血管造影。分析了全视网膜光凝后视力下降的原因和发生率。所有病人用氩激光光凝治疗,光斑500μm,曝光时间0.05秒,能量以产生低～中等强度的损害为度。在3～21天内治疗2次或2次以上,最
Retinal photocoagulation for the treatment of diabetic proliferative retinopathy has been shown to effectively reduce the incidence of severe vision loss in patients. However, laser photocoagulation does not eliminate the possibility of vision loss, especially in “crisis” eyes of diabetic retinopathy. In addition, in a considerable part of the eyes, the damage of central vision is related to the side effects of laser photocoagulation. The authors retrospectively reviewed retinal photocoagulation and fundus fluorescein angiography in patients undergoing total retinal photocoagulation for treatment of diabetic proliferative retinopathy. The causes and incidence of decreased visual acuity after panretinal photocoagulation were analyzed. All patients treated with argon laser photocoagulation, spot 500μm, exposure time 0.05 seconds, the energy to produce low to moderate intensity of the damage for the degree. In 3 to 21 days to treat 2 or more times, most
