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.
