松弛性视网膜切开治疗穿孔伤性视网膜脱离

Relaxing retinotomy for the treatment of perforating traction retinal detachment

目的 探讨松弛性视网膜切开对穿孔性牵引性视网膜脱离 (perforating traction retinaldetachment,PTRD)的治疗价值和效果。 方法 对 1998～ 2 0 0 1年本院住院行松弛性视网膜切开的 2 1例PTRD患者作回顾性分析。 结果 出院时视网膜解剖均复位 ,数指 (counting finger,CF)以上视力 12例占 5 7% ,最好视力为 0 .0 5。 18例患者随访时间 6～ 2 4个月 ,解剖复位 14例占 77.8%。 结论 为了提高PTRD的解剖复位率 ,松弛性视网膜切开是有效方法之一。尤其适用于伴有视网膜嵌顿、前部增生性玻璃体视网膜病 (anterior proliferative vitreoretinopathy,a PVR)、机化条索的 PTRD患者。

Objective To explore the therapeutic value and effects of relaxing retinotomy for perforating traction retinal detachment(PTRD). Method A retrospective survey was done in 21 patinets (21 eyes) with PTRD who underwent vitrectomy combined with relaxing retinotomy in our hospital from 1998 to 2001. Results The retinae were completely reattached in all 21 cases. The visual acuity of 12 patients (57%) was counting finger, and the best visual acuity was 0.05. Among the 18 patients who were followed up for 6 to 25 months, 14(77.8%) remained retinal reattachment. Conclusions Relaxing retinotomy is effective for anatomic reattachment of PTRD, especially to the patients with retinal incarceration and severe proliferative vitreoretinopathy.
