To evaluate the long-term results of vitrectomy for complications of proliferative diabetic retinopathy.
Five-year follow-up examinations were obtained on 33 eyes of 24 patients that underwent vitrectomy. The preoperative status of macula was no detachment(group 1, 9 eyes), macular detachment(group 2, 17 eyes), and traction macular fold (group 3, 7 eyes).
The retina was successfully reattached in 17 eyes(100%). The final visual acuity obtained was as follows: 75% of the eyes had acuity of 0.1 or better in group 1, 65% in group 2, and 86% in group 3; 44% had acuity of 0.5 or better in group 1, 24% in group 2, and 14% in group 3; and 11% had acuity of 0.05 or worse in group 1, 18% in group 2, and 0% in group 3. 11% of the final visual acuity was worse than the postoperative best visual acuity(three lines or more) in group 1, 29% in group 2, and 14% in group 3. The causes of worsening in vision were optic or macular atrophy.
Vitrectomy for complications of proliferative diabetic retinopathy is valuable in improving the patient's visual acuity.
评估玻璃体切除术治疗增生性糖尿病视网膜病变并发症的长期效果。
对24例接受玻璃体切除术的患者的33只眼睛进行了为期五年的随访检查。黄斑术前状态为未脱离（第1组，9只眼）、黄斑脱离（第2组，17只眼）和黄斑牵引褶皱（第3组，7只眼）。
17只眼（100%）视网膜成功复位。最终获得的视力如下：第1组75%的眼睛视力为0.1或更好，第2组为65%，第3组为86%；第1组44%的眼睛视力为0.5或更好，第2组为24%，第3组为14%；第1组11%的眼睛视力为0.05或更差，第2组为18%，第3组为0%。第1组最终视力比术后最佳视力差（3行或更多）的比例为11%，第2组为29%，第3组为14%。视力恶化的原因是视神经或黄斑萎缩。
玻璃体切除术治疗增生性糖尿病视网膜病变并发症对提高患者视力有价值。
