严重眼球破裂伤Ⅱ期玻璃体手术的效果观察

Effects of vitrectomy in secondary surgery for severe ocular rupture

目的观察严重眼球破裂伤Ⅱ期玻璃体视网膜手术的效果。方法对2005年2月～2007年12月问我院收治的145例（146眼）严重眼球破裂伤行Ⅱ期玻璃体视网膜手术，观察手术效果。结果视力提高者105眼（71．92％），不变者36眼（24．66％），下降者5眼（3．42％）。术前无光感22眼，术后获得光感及光感以上视力12眼（54．55％）。术前视网膜脱离56眼，术后复位51眼（91．07％）。Ⅱ期玻璃体视网膜手术后发生视网膜脱离者15眼（10．27％），12眼再次手术，术后均复位。结论正确的初期修复和适时、恰当的Ⅱ期玻璃体视网膜手术可以有效治疗严重眼球破裂伤，挽救大多数受伤眼的视力。

Objective To explore the therapeutic effect of severe ocular rupture after secondary vitrectomy. Methods We performed secondary vitreoretinal surgery on 145 patients （146 eyes） suffering from severe ocular rupture who were admitted to our hospital from February 2005 to December 2007, the therapeutic effect was observed. Results The visual acuity of 105 eyes （71.92 % ） improved in different degree compared with that before operation. The visual acuity remained unchanged in 36 eyes （24.66 % ） ,and 5 eyes （3.42%） had worse vision. Among 22 eyes with no-lightperception（NLP）, 12 eyes （54.55%） had light-perception or over. The retina was reattached in 51 eyes （91.07%） from totally 56 eyes of retinal detachment before operation. 15 eyes （10.27%） had recurrent retina detachment in which 12 eyes had undergone vitrectomy again and had got the reina reattached. Conclusion Through proper primary repair of the wound, and adequate and timely vitreous surgery on the second stage, the majority of traumatic eyeballs could be salvaged and effective vision could be restored.
