假性近视眼的性质分析

An Appraisal on the Nature of Pseudomyopia

目的对假性近视眼的性质进行探讨。方法对典型假性近视眼１００例及有近视现象的３２８名中小学生作了检查，包括远近视力、睫状肌麻痹下验光及眼底检查。结果１００例假性近视眼检影以远视为主（８３％），少数为混合散光（１１．５％），个别为近视（５．５％）。５６名假性近视眼３年后复查，除２例外，其它无一变成近视眼。结论假性近视眼多为异常视力负荷而引发的一种近视现象（症状性近视），本质上不是近视眼。

Objective To explore the nature of pseudomyopia.Methods Visual acuity test,cycloplegic skiascopy and fundus examination of 100 cases of pseudomyopia and 328 students of 6￣16 years old with nearsight were investigated.Results The refraction of pseudomyopia was mainly hyperopia.There were 83.0% of hyperopia,11.5% of mixed astigmatism and 5.5% of myopia in these typical pseudomyopia cases.After 3 year follow up, these pseudomyopia did not change to myopia except 2 cases only.Conclusion Pseudomyopia is only a myopia phenomenon (symptomatic nearsight) and different from myopia in essence.
