雾视法和托吡卡胺散瞳法对假性近视的诊断价值

Comments on the diagnostic value of the fogging method and the mydriatic method of Tropicamide to diagnose teen agers pseudomyopia

为了评价雾视法和托吡卡胺散瞳法诊断假性近视的临床实用价值，作者对本市某校初一学生１５４人２７２眼分别采用雾视法和托吡卡胺散瞳法鉴别真、假性近视眼，经散瞳检影验光验证。结果显示二者的特异度、预告值、准确度及阳性似然比高，误诊率低，均为诊断假性近视的有用方法，如果联合使用可提高诊断假性近视的灵敏度，对于假性近视的普查普治很有价值。近视病程与假性近视呈负相关，性别与调节因素无关。

In order to comment on the practical value in clinic of the fogging method and the mydriatic method of tropicamide to diagnose pseudomyopia,the author used both methods on 272 eyes of 154 students at a junior middle school to distinguish pseudomyopia from real myopia.The results were verified by the test of retinoscopy.The results showed that they had high specificity,predictive value,accuracy,positive likelihood ratio and low misdiagnostic rate.So they were both useful methods to diagnose pseudomyopia.If they were used combinedly,the sensitivity increased.So both methods had high value in large scale examination and treatment of pseudomyopia.There was negative correlation between the course of myopia and the proportion of pseudomyopia.There was no relation between sex and accommodation.
