眼内异物的B超诊断及漏诊分析

目的 分析眼内异物的B超诊断图像特征及漏诊情况.方法 应用Cine-Scan法国光太AB超声诊断仪对我院126例手术前眼内异物外伤患者进行B超检查,并根据经手术后情况进行分析.结果 金属异物占74.6%,非金属异物占25.4%;球内异物占81.8%、眼球壁异物占9.5%和眶内异物占7.1%;漏诊占1.6%.漏诊原因主要是B超未能发现微小异物和临床医生未对有眼内异物征象的外伤患者行B超检查.结论 B超检查对眼内异物具有较高的临床诊断价值.在眼科临床诊疗过程中,对有眼外伤史尤其有眼内异物症状的患者,B超应列为常规检查,以避免漏诊、误诊.

Diagnostic Value of B-type Ultrasound for intraocular foreign bodies and missed diagnosis in 126 inpatient cases

Objective To evaluate the roles of diagnosing intraocular foreign bodies (IOFB) and missed diagnosis with B-type ultrasound. Methods Retrospective study of 126 clinic inpatient cases. Results The rate of metallic foreign body(MFB) was 74.6%, the rate of intraocular foreign body was 81.8 %, the rate of intraorbital foreign body was 7.1%; The missed diagnosis rate of B-type ultrasound for intraocular foreign bodies was 1.6%, the discovering rates were decreased for anterior segment and retrobulbar intraocular foreign bodies,and the showing rate was high to the vitreous opacity and retinal detachment caused by intraocular foreign bodies. Conclusion Type ultrasound can provide the required information on diagnosis and surgery design of IOFB. Small intraocular metal foreign bodies are easily misdiagnosed and missed diagnosed. Routine examination including B-type ultrasound for patients who had symptoms of intraocular foreign bodies, can obviously reduce the misdiagnosis and missed diagnosis.
