糖尿病视网膜病变视网膜光凝治疗疗效观察

目的：观察氩激光视网膜光凝（Panretinal photocoagulation,PRP)治疗糖尿病视网膜病变（diabetic retinpathy,DR)的临床疗效。方法：根据眼底荧光血管造影（Fundus fluorescence angiography,FFA)的结果。对87例143眼分别为增殖前期糖尿病性视网膜病变（Preproliferative diabetic retinopathy,PPDR)79眼，增殖期糖尿病性视网膜病变（Proliferative diabetic retinopathy,PDR)64眼，进行氩激光视网膜光凝治疗，治疗前及完成最后一次光凝后3个月对患者的视力，眼底，FFA进行检查并追踪观察6个月-2年。结果：本组143眼经视网膜光凝治疗后122眼有效，总有效率为85.31%，其中PPDR79眼有效73眼，有效率为92.41%;PDR64眼有效49眼，有效率为76.56%，光凝治疗后视力提高有32眼，占23.38%;87眼视力稳定不变，占60.84%；视力下降24眼，占16.78%。本组病例治疗过程及治疗后无发生并发症。结论：氩激光视网膜光凝术治疗糖尿病性视网膜病变是安全。有效的方法。

Observation on Clinical Effects of Panretinal Coagulation for Diabetic Retinopthy

Objective: Observing and evaluating the clinical effects of panretinal photocoagulation with Argon laser for diabetic retinopthy.Methods: According to the results of fundus fluorescence angiography (FFA), panretinal photocoagulation with Argon laser were performed on 143 eyes(87 cases) of diabetic retinopthy, including 79 eyes with preproliferative diabetic retinopathy (PPDR), 64 eyes with proliferative diabetic retinopathy (PDR) . Examination about FFA, visual acuity and fundus condition were carried out before laser treatment and 3 months after photocoagulation. The regular following up lasted for 6 months to 2 years. Results: Laser photocoagulation proved effective in 122 eyes (85. 31% ) with diabetic retinopthy, including 73 eyes (92. 41% ) with PPDR, 49 eyes(76. 56% ) with PDR. The visual acuity were improved in 32 eyes (23. 38% ), no changes in 87 eyes (60. 84% ), decrease in 24 eyes (16. 78% ). No complication was found in all patients. Conclusions: Panretinal photocoagulation with Argon laser is a safe and effective method to control the condition of diabetic retinopthy.
