螺旋CT诊断机械性眼外伤的临床应用价值研究

Clinical Application Value of Spiral Ct in The Diagnosis of Mechanical Ocular Trauma

目的 研究螺旋CT诊断机械性眼外伤的临床应用价值。方法 选取2022年5月—2023年5月单县南城人民医院收治的90例(95眼)疑似机械性眼外伤患者为研究对象,均接受螺旋CT和眼部超声检查,以裂隙灯检查结果作为金标准,比较两种检查方法的诊断结果和诊断效能。结果 90例(95眼)疑似机械性眼外伤患者经裂隙灯检查显示,有86眼确诊;运用螺旋CT检查,有75眼为阳性,20眼为阴性;运用眼部超声,有60眼为阳性,35眼为阴性。螺旋CT诊断的准确度、灵敏度、特异度、阳性预测值、阴性预测值均高于眼部超声,差异有统计学意义(P均<0.05)。结论 与超声检查相比,螺旋CT能提高机械性眼外伤的诊断效能。

Objective To study the clinical application value of spiral CT in the diagnosis of mechanical ocular trauma.Methods A total of 90 patients(95 eyes) with suspected mechanical eye trauma admitted to Nancheng People's Hospital of Shanxian County from May 2022 to May 2023 were selected as the study objects.All of them received spiral CT and ocular ultrasound examination,and the examination results of slit lamp were used as the gold standard.The diagnostic results and diagnostic efficiency of the two methods were compared.ResultsI n 90 patients(95 eyes) with suspected mechanical eye trauma,86 eyes were confirmed by slit-lamp examination.By spiral CT,75 eyes were positive and 20 eyes were negative.Using eye ultrasound,60 eyes were positive and 35 were negative.The diagnostic accuracy,sensitivity,specificity,positive predictive value and negative predictive value of spiral CT were higher than those of ocular ultrasound,and the differences were statistically significant(all P<0.05).Conclusion Compared with ultrasound examination,spiral CT can improve the diagnostic efficiency of mechanical ocular trauma.
