目的:探讨玻璃体切割术治疗严重的眼外伤无光感眼的疗效。方法:对9例9眼严重外伤后的无光感眼行玻璃体视网膜手术,并观察其疗效。随诊6～24(平均10)mo。结果:在9例外伤后无光感眼中,4例恢复了光感或光感以上的视力,5例仍无光感。眼外伤后无光感的主要原因是严重的屈光间质混浊,视网膜破损、脱离及脉络膜水肿。结论:严重眼外伤无光感眼经及时的玻璃体切割术可获得一定的视力。

AIM:To assess the efficacy of vitreous surgery for treatment of open ocular trauma with no light perception(NLP).METHODS:Vitreoretinal surgery was performed on 9 cases(9 eyes) with NLP after serious ocular trauma,and the efficacy was observed.The follow-up time was 6-24 months(average 10 months).RESULTS:Postoperatively,4 of 9 cases had visual acuities of light perception or above.5 cases remained NLP.NLP after ocular trauma was mainly due to severe refractive media opacity,retinal damage,detachment and choroidal edema.CONCLUSION:Some patients with NLP after ocular trauma may get certain visual acuities after surgical treatment of vitrectomy.
