眶内球外病变与眼环夹角大小对其定性诊断的价值

目的探讨眶内球外病变与眼环夹角大小对其定性诊断的价值。方法 42例眶内球外与眼环相关病变,根据其与眼环的夹角可分为与眼环成锐角10例及成钝角病变32例,且与病理结果对照,并计算该分类方法对眶内球外病变定性诊断的敏感度（SE）、特异度（SP）、准确度（AC）、阳性预测值（PPV）及阴性预测值（NPV）。结果该分类标准对良性肿瘤定性诊断的SE、SP、PPV及NPV分别为66.7%、100%、100%和84.4%;AC为88.1%。结论按与眼环夹角大小对眶内球外病变进行分类有助于对其定性诊断,眼环外病变与眼环成锐角的为良性肿瘤,而与眼环成钝角的病变,多为炎性病变或恶性肿瘤。

The Value of the Angle of the Disease to the Eye Link to Diagnose Diseases Related with Eye Link in Orbit

Objective To evaluate the value of the angle of the disease to the eye link to diagnose diseases related with eye link in orbit.Methods All the 42cases 67eyes of diseases related with eye link in orbit had been confirmed by operation and/or pathology.According to the angle of the disease to the eye link,diseases were classified as acute angle disease and obtuse angle disease.The SE,SP,AC,PPV and NPV of such classification method to diagnose diseases related with eye link in orbit were calculated.Results The SE,SP,AC,PPV and NPV of such classification method to diagnose bengin lesions related with eye link in orbit was 66.7%,100%,100%and 84.4%,and the AC was 88.1%.Conclusion It is useful for us to diagnose diseases related with eye link in orbit that According to the angle of the disease to the eye link,diseases were classified as acute angle disease and obtuse angle disease.Acute angle diseases outside eyeball are all benign lesions,and most of obtuse angle diseases are inflannatory lesions or malignant tumours.
