摘　　要：目的探讨A与B超、CT对眼内异物的诊断及手术的指导意义。方法回顾分析2009年5月至2014年3月在延安市人民医院就诊的48例（48只眼）眼外伤术前诊断为眼内异物患者的A与B型超声图像和CT图像，并与手术所见进行对比观察。结果48例中确诊眼内异物43例。术前A与B超检查漏诊3例，出现假阳性5例，检出率83．33％（40／48）；正确诊断40例，确诊率93．02％（40／43）。CT扫描漏诊8例，否认超声5例的假阳性图像，检出率为72．92％（35／48）；正确诊断35例，确诊率81．40％（35／43）。综合分析双向检查图像，术前诊断眼内异物43例，与手术结果完全一致，诊断准确率提高至100％。A与B超对诊断的40例异物定位准确同手术所见一致，优于CT。CT对诊断的35例异物定性准确率均同手术所见一致。结论A与B超和CT对眼内异物的诊断各有优缺点，A与B超联合CT可提高眼内异物诊断准确率。Objective To approach the directions significance of A and B-scan ultrasonograghy and CT in intraocular foreign body＇s diagnosis and intraocular foreign body＇s operation. Methods A retrospective analysis 48 examples （48 eyes） injury patients who diagnosed intraocular foreign body from May 2009 to March 2014 by A and B-scan ultrasonograghy and CT preoperative in Yan- an People＇s Hospital. The examine image was compared to the finding in operation. Results There were 43 examples been final diagnosed intraocular foreign body in 48 examples. In A/B-scan ultra- sonograghy preoperative, 3 examples were missed diagnosis, 5 false positive, detection rate was 83.33%（40/48）; 40 examples were the same as the final diagnosis, so the accuracy of diagnosis of A/ B-scan ultrasonograghy was 93.02%（40/43）. In CT examination before surgery, 8 examples missed di- agnosis, 5 false positive, detection rate was 72.92%（35/48）, 35 examples were the same as the final diagnosis, so the accuracy of diagnosis of CT was 81.40%（35/43）. Meta-analysis biplane examina- tions images, preoperative diagnosis intraocular foreign body were 43 examples, the accuracy of diag- nosis was raised to 100%. In A and B-scan ultrasonograghy, 40 cases foreign body localization detec- tion were the same as intraoperative findings, and 35 cases foreign body localization detection in CT were the same as intraoperative findings. In A and B-scan ultrasonograghy, detected foreign body qualitative accuracy was 91.67%（44/48）, better than 45.83%（22/48）in CT. Conclusions The A and B-scan ultrasonograghy and CT have themselves merit and demerit. A/B-scan ultrasonograghy combine with CT can improve the diagnosis accurate to intraocular foreign body; but A and B-scan ultrasonograghy has an advantage to CT in foreign body induced intraocular secondary alteration, they have important clinical significance in guiding operation.
