氩激光光凝治疗糖尿病视网膜病变疗效观察

目的：观察氩激光视网膜光凝术治疗增殖前期和增殖期糖尿病视网膜病变（diabetic retinopathy,DR）疗效。方法:对70例（118眼，其中增殖前期25眼，增殖期93眼）DR病人，依病变程度分别行全视网膜光凝或次全视网膜光凝治疗。术后随访1年，观察光凝后患者的视力、眼底及荧光血管造影变化，并进行分析和对比。结果：光凝治疗后102眼有效。总有效率为86.4%，其中增殖前期23眼有效，有效率92％，增殖期79眼有效，有效率85％，二者有显著差异（P＜0.01），治疗后27眼视力提高（23％）；77眼视力不变（65％）；14眼视力下降（12％）。在治疗前有黄斑水肿的62眼中，治疗后有13眼黄斑水肿安全吸收（21％），40眼部分吸收（64.5%），9眼不变（14.5%）。结论：氩激光视网膜光凝术是治疗DR的有效手段，对其增殖前期应尽早发现及时进行光凝治疗，以阻病情发展，保护视功能。

Argon laser photocoagulation for diabetic retinopathy

Objective:To observe the therapeutic effect of argon laser photocoagulation for the pre proliferative and the proliferative diabetic retinopathy (DR). Methods:According to the degree of the disease,panretinal photocoagulation or mild panretinal photocoagulation were separately performed on 118 eyes of 70 cases,among which there were 25 eyes for pre proliferative DR and 93 eyes for proliferative DR.The postoperative follow up was 1 year.The visual acuity,fundus examinations and fundus fluorescein angiography (FFA) were analyzed and compared Results:The 102 eyes were effective among the 118 eyes after treatment;total effective rate was 86 4%.23 eyes were effective among the 25 eyes with the pre proliferative DR (effective rate 92%).79 eyes were effective (effective rate 85%) among the 93 eyes with the proliferative DR.The difference between the two groups was statistically significant (P<0 01).There were 27 eyes in which the final vision acuity had been increased (23%),77 eyes in which the final vision acuity had no change (65%) and 14 eyes in which the final vision acuity had been decreased (12%) among the effective 118 eyes.Cystoid macular edema (CME) of 13 eyes had completely been absorbed (21%),of 40 eyes partially been absorbed (64 5%) and of 9 eyes had not been changed (14 5%) among the 62 eyes with CME after the treatment. Conclusions:Argon laser photocoagulation is an effective method to treat DR.The patients with the pre proliferative and the proliferative DR should be found as early as possible and photocoagulation should be performed as soon as possible in order to prevent DR from the development and to protect visual function.
