目的观察分析玻璃体切除术治疗增生型糖尿病视网膜病变(PDR)的效果。方法对行玻璃体手术治疗的54例(63眼)PDR病例进行回顾性分析,并总结造成术后视力不良的原因。结果术后随访5～24个月,术后矫正视力改善48眼(76.19%),63眼中视力≥0.01者由术前23眼(36.51%)增加到术后49眼(77.78%),其中视力≥0.1者由术前3眼(4.76%)增加到术后27眼(42.86%),8眼(12.70%)与术前比较变化不明显,7眼(11.11%)较术前稍有下降。Ⅳ,V期患眼术后视力改善程度(84.78%)明显好于Ⅵ期者(52.94%)。结论玻璃体切除术是治疗PDR的有效方法,合理掌握手术时机、减少术中术后并发症对治疗效果很关键。
Objective To analyze the effect of vitrectomy on proliferative diabetic retinopathy (PDR). Methods Retrospective analysis was performed on 54 cases (63 eyes) of PDR treated with vitrectomy, and the causes of postoperative visual acuity were summarized. Results The follow-up was 5 to 24 months after operation. The corrected visual acuity improved 48 eyes (76.19%), 63 eyes (≥0.01) increased from 23 eyes (36.51%) to 49 eyes (77.78%) after operation, ≥0.1 increased from 3 eyes (4.76%) preoperatively to 27 eyes (42.86%) postoperatively, while 8 eyes (12.70%) had no significant changes compared with preoperative, while 7 eyes (11.11%) decreased slightly compared with that before operation. The degree of visual acuity improvement in patients with stage Ⅳ and V was significantly better than that of stage Ⅵ (84.78% vs 52.94%). Conclusions Vitrectomy is an effective method for the treatment of PDR. It is very important to know the timing of surgery and reduce the intraoperative and postoperative complications.
