眼内异物摘出术手术径路的选择

Pathway selection for extraction of intraocular foreign body

目的寻求摘出眼内异物的最佳手术径路。方法对22例眼内异物进行回顾性研究，12眼用传统的巩膜切开法，10眼用经睫状体平坦部玻璃体切除术摘出异物。结果传统方法和玻璃体切除术法均成功地摘出异物。单纯伴玻璃体出血机化者，经玻璃体手术术后视力明显提高。同时伴视网膜脱离者，异物摘出联合视网膜复位术后视力恢复不理想。结论眼内异物摘出以不进一步损伤眼组织为原则，必须综合分析异物位置及其并发症，以选择手术路径。

Objective To find the best way to extract intraocular foreign body (IOFB). Methods 22cases of IOFBwerretrospectively.12 eyes underwent a traditional sclerotomy to remove the IOFBs.While a pars plana vitrectomy(PPV)plus IOFB extraction was performed in an other 10.Results Ether selerotomy or PPV extracted each IOFB. The re moval rate was 100%. The cases,accociated with vitreous hemorrhage on ly, could get significant improrement in visual actuity after vitrectomy combined with IOFB extraction.However visual acuity outcomes in the cases with retinal detachment were discouraging after IOFB extraction plus retina reattachment suattachment surgery.Conclusions Extraction of IOFB can't result in further injuries to eyes.The selection of its pathway should be made fter a thoughtful analysis. Both location of the IOFB and complica tion of ocular trauma shauld take into account.
