摘要目的 探讨影响眼内异物伤视力预后的相关因素.方法 对59例(59眼)眼内异物病例进行回顾性分析.结果 49例磁性异物中32例从巩膜外路切口摘出,其余17例及10例非磁性异物经玻璃体切出.术后随访3～30个月平均(12.0±4.7)月,最好矫正视力:光感～0.02者6例,0.02～0.05者13例,0.05～0.3者18例,＞0.3者22例,术后视力较术前有明显改善(P＜0.05).术后的主要并发症是增生性视网膜病变(PVR)、视网膜脱离、黄斑前膜及继发性青光眼.结论 眼球伤口部位、异物的位置、眼内炎、PVR、视网膜脱离、黄斑前膜等是影响眼内异物伤视力预后的主要因素.

abstractsObjective To study the factors affecting visual prognosis of intraocular foreign bodies injuries. Methods Clinical data of 59 cases (59 eyes) with foreign bodies were analyzed retrospectively.Visual acuity and complications were observed. Results 32 cases (32 eyes) underwent electro manet extraction, and 27 cases (27 eyes) underwent vitrectomy extraction. The follow up time was 3 to 30 months (mean 12 ±4.7), the final corrected visual acuity was LP -0.02 in 6 eyes, 0.02 -0.05 in 13 eyes, 0.05-0.3 in 18 eyes, ≥0. 3 in 22 eyes. The post-operative complication included proliferative vitreoretinopathy (PVR), retinal detachment, macular epiretinal membrane and glaucoma. Conclusions Cornea wound,position of foreign bodies within ocular, retinal damage region, endophthalmitis and post-operative complications are important factors affecting the visual prognosis of intraocular foreign body injuries.
