玻璃体手术治疗复杂性眼球外伤临床观察

目的探讨在复杂性眼球外伤治疗中玻璃体手术的疗效和意义。方法回顾分析复杂眼球外伤68只眼，因玻璃体大量积血混浊、伴外伤性视网膜脱离及增生性玻璃体视网膜病变（PVR）、眼后段异物、眼内炎、晶体后脱位等病变，行常规闭合式玻璃体切除术，同时根据不同伴随病变联合相应的手术治疗。结果66只眼按计划完成玻璃体手术。伴发视网膜脱离35只眼、眼后段异物19只眼、眼内炎13只眼及晶体后脱位8只眼，其治愈率分别为86％、89％、77％和100％。术后64只眼行视力检查，45只眼（70％）视力有明显提高。结论以玻璃体切除术为主的联合手术是治疗复杂眼球外伤的有效方法，尤其伤及眼后段的外伤眼多能得到挽救，视力不同程度提高。

Vitreous Surgery for Complicated Ocular Trauma

Objective To investigate significance of vitreous surgery for complicated ocular trauma.Methods A retrospective survey was done in 68 complicatedly injured eyes undergoing routine closed vitrectomy due to vitreous opacity with massive hemorrhage, or with traumatic retinal detachment and proliferative vitreoretinopathy (PVR), foreign bodies in posterior segment, endophthalmitis, posterior-dislocation of lens and so on, and most of them received the combined operations simultaneously.Results Vitreous surgeries on total 66 eyes were done on schedule. Retinal detachment, foreign bodes in posterior segment, endophthalmitis, and posterior-dislocation of the lens happened in 35, 19, 13 and 8 injured eyes, and their curative rates were 86%, 89%, 77% and 100% respectively. Postoperative visual acuity of 45 eyes (70%) was obviously improved.Conclusion Vitrectomy combined with supplement operations is an effective treatment for the complicated ocular trauma, by which most of traumatic eyes, especially severely injured in posterior segment, can be well rescued, and the visual acuities can also be improved to varying degrees.
