目的:探讨急诊玻璃体手术治疗眼后段异物伤的临床疗效。方法:回顾性分析2005-01/2010-12在我院诊断为后段眼内异物的眼球穿通伤,急诊行玻璃体切割、异物取出术患者32例32眼的临床资料。结果:患者30例一次性取出异物。术后视力改善12例,视力不变的10例,视力下降的10例。术后继发性青光眼4例,视网膜脱离3例,眼球萎缩的2例。术中1例因角膜混浊、1例因眼内出血加重终止手术,择期手术成功取出异物。结论:急诊行玻璃体切割、异物取出术是治疗眼内异物的有效而及时的处理方法。

AIM:To investigate the therapeutic effects of emergent vitrectomy for posterior segment intraocular foreign bodies.METHODS:A retrospective study of 32 consecutive cases(32 eyes)of pars plana vitrectomy for the removal of posterior segment intraocular foreign bodies in emergency treatment during January 2005 to June 2010 was conducted.The study group consisted of 32 eyes for 28 males and 4 females,aged from 18 to 50 years old.The site of wound entrance was in the cornea in 12 cases,in the sclera in 8 cases,and in the corneoscleral limbus in 12 cases.The intraocular foreign body was found to be in the vitreous in 22 cases and embedded in the retina in 10 cases.Associated lesions were traumatic cataract in 22 cases,vitreous hemorrhage in 29 cases,hyphema in 4 cases,retinal detachment in 5 cases.RESULTS:The foreign bodies were extracted successfully in 30 cases.Postoperative visual acuity improved in 12 cases,did not change in 10 cases,and decreased in 10 cases.During the postoperative period,secondary glaucoma were observed in 4 cases,retinal detachment in 3 cases,phthisis bulbi in 2 cases.Operation was canceled because of corneal opacity in 1 case and because of intraocular hemorrhage in the other case,whose foreign bodies were successfully removed in the elective surgery.CONCLUSION:Vitrectomy for emergency treatment of foreign bodies is found to be an effective therapeutic approach in removing posterior segment intraocular foreign bodies in time.
