摘要
目的:探讨激光全视网膜光凝术激光量与疗效的关系。方法:回顾性分析我院应用氩蓝绿和氪红激光全视网膜光凝治疗的新生血管性青光眼52只眼、视网膜中央静脉阻塞47只眼和增殖型糖尿病视网膜病变231只眼的临床资料。结果:新生血管性青光眼激光全视网膜光凝术的有效平均视网膜光凝斑总数是1500个左右,增殖型糖尿病视网膜病变及视网膜中央静脉阻塞激光全视网膜光凝的有效平均光凝斑总数是1000个左右,二者的平均光凝斑总数有显著差异(P<0.01)。结论:根据视网膜病变的病情不同,选择合适的激光波长和确保有效光斑的范围与密度是激光全视网膜光凝术成功的关键。
PURPOSE:To probe the dosage and effect of lasers in panretinal photocoagulation.METHODS:Three kinds of ocular diseases,e.g., neovascular glaucoma(NVG)in 52 eyes,central retinal vein occlusion(CRVO)in 47 eyes,and preproliferative and proliferative diabetic retinopathies(PDR)in 231 eyes ,treated with krypton red and argon blue green laser panretinal photocoagulation in ocular clinic of our hospital,were analysed clinically and retropectively.RESULTS:The effetive average numbers of laser burns in panretinal photocoagulation in this series after clinical analysis statistically were found to be 1 500 in NVG,and 1 000 in PDR and CRVO respectively.CONCLUSION:To select the proper laser,its wave length,therapeutic position and volume of laser burns in accordance with the specific circumstances of various retinopthies is of extreme importance in success of laser panretinal photocoagulation.
