内镜引导玻璃体切除治疗伴严重角膜浑浊的增生性玻璃体视网膜病变

The vitrectomy inducted by ocular micro-endoscope to treat traumatic PVR combined with severe corneal opacity

目的对内镜引导玻璃体切除治疗伴有严重角膜浑浊的外伤性增生性玻璃体视网膜病变（PVR）进行评价。方法采用回顾对照研究。37例（37眼）伴有严重角膜浑浊的外伤性PVR分别应用内镜引导玻璃体切除术（A组19例）和经临时人工角膜玻璃体切除联合穿透性角膜移植术（B组18例）治疗。就等待手术时间、视网膜复位率、术后视力进行比较分析。结果术后随诊2～40个月。A组术前等待时间〈1个月者13／19例，明显优于B组的5／18例（P〈0．05）。视网膜复位率及术后视力差异无统计学意义（P〉0．05）。结论对于伴有严重角膜浑浊的外伤性PVR用内镜引导玻璃体切除术可有效地提早手术时间，使更多的患者得到有效的治疗，同时可节省大量的角膜材料。

Objective To evaluate the efficacy of the vitrectomy inducted by ocular micro-endoscope in treatment of traumatic PVR combined with severe corneal opacity. Methods Retrospective case-controlled study, 37 patients were enrolled in this study. Each person was suffered with traumatic PVR and severe cornea opactity. Group A （19 patients/19 eyes） was treated with vitrectomy inducted by ocular micro-endoscope. Group B （ 18 patients/18 eyes） was received with vitretomy combined with the penetrating keratoplasty. Results After 2 -40 months follow-up, group A was equivalent to group B in the field of the retina reattachment rate and the recovery of the visual acuity. The pre-operation time of 13 patients in the group A （19 patients） was less 1 month, which is statistically significant better than 5/18 of the group B. Conclusions The vitrectomy inducted by ocular micro-endoscope is an effective method to treat traumatic PVR, which combined with severe corneal opacity.
