摘　　要：目的:进一步了解糖尿病视网膜病变(DR)全视网膜光凝术(PRP)后中、长期随诊的激光量和疗效的临床结果。方法:63例增殖期糖尿病视网膜病变(PDR)PRP术后随诊12～132个月(平均43.2个月)的临床资料回顾分析。结果:63例PDR患者PRP术的平均视网膜光凝斑总数975个。视力改变:提高者占24.2％,不变者占35％,下降者占40.8％。主要晚期并发症是程度不等的玻璃体视网膜纤维膜形成及少数病例(4例5只眼)发生1～3次不同程度的玻璃体出血。结论:PDR病例PRP术后中、长随诊的激光量——平均总视网膜光斑数1000个左右;60％的病例视力保持不变或改善,40％的病例视力下降,病情控制。强调了适宜的视网膜光凝范围、适宜的激光波长和适宜的视网膜有效光斑是PRP术成功的关键。还讨论了DR激光治疗后视力下降的因素和主要晚期并发症。Objective:To further evaluate the dosage and therapeutic effects of panretinal photocoagulation(PRP) for proliferative diabetic retinopathy(PDR)after medium to long-term follow-up. Methods:63 patients with PDR were treated with laser PRP and fol-lowed-up 12-132 months(average 43.2 months).The data were analysed retrospectively.Results:The average numbers of effective laser burns in the 63 patients were 975 spots. Vision acuity changes:improved in25 eyes(24.2%),unchanged in 36 eyes(35%),decreased in 42 eyes(40.8% ). Conclusion: Selections of optimal laser wavelength, therapeutic position, intensity and numbers of laser burns, are the keys of successful treatment for PRP.
