眼前段微小异物UBM定位及异物摘出联合手术

目的：探讨眼前段微小异物的超声生物显微镜（UBM）定位的意义及异物摘出联合白内障摘出等手术的效果，方法：应用其他检查方法未能确定的12例眼前段微小异物，同时合并铁质沉着症，通过UBM检查，明确异物位置并采取异物摘出联合白内障囊外摘出，玻璃体切除，晶状体切除和／或人工晶状体植入手术。结果：12眼均顺利摘出异物，同期植入人工晶状体9眼中的8眼获得0．5以上良好视力，结论：高度怀疑眼前段微小异物，UBM检查是一种极好的定位方法：联合手术可使视力迅速恢复。

Localization with UBM and treatment with combined surgery for the anterior segment intraocular micro-foreign-bodies

Objective To study the localization with ultrasound biomicroscope(UBM) of intraocular micro foreign bodies in the anterior segment and the efficacy of combined surgery in the removal of foreign body.Methods We used UBM in the identification of intraocular micro foreign bodies in the anterior segment in 12 patients (12 eyes) with ocular siderosis and removed the foreign bodies surgically combined with extracapsular cataract extraction,vitrectomy,lensectomy and/or intraocular lens implantation.These foreign bodies were not found by other examinations previously.Results We removed the foreign bodies successfully in the 12 eyes and implanted intraocular lens in 9 eyes in one operation.Eight eyes out of the 9 achieved visual acuity of 0.5 or better.Conclusion Ultrasound biomicroscopy is a very effective method in the localization of micro foreign bodies in the anterior segemnt in patients with strong suspicion of intraocular foreign body and the patients' visual acuity may recover rapidly.
