屈光检查对视功能的测定具有很大意义。对于任何视力减退的病例,只有在排除屈光不正的基础上,才能确定其性质而作出正确诊断。临床上将由屈光不正或弱视所引起的视力减退病例,误诊为球后视神经炎等的错误,主要是因为未作屈光的检查,揭露出视力减退的原因。屈光检查也是判断眼病治疗效果和预后的一种手段,且有些患者有眼睛疲劳、斜视或弱视,它们都和屈光不正有关。因此,认为屈光检查只是验光士(师)或眼镜店的事,而不是眼科医生的本职业务,这种认识显然是错误的。
Refractive assessment of visual function is of great significance. For any case of vision loss, only to exclude the basis of refractive errors, to determine its nature and make the correct diagnosis. Clinical errors caused by refractive errors or amblyopia cases of vision loss, misdiagnosed as retrobulbar optic neuritis and other errors, mainly because no refractive examination revealed the reason for vision loss. Refractive assessment is also a means to determine the effect and prognosis of eye disease, and some patients have eye fatigue, strabismus or amblyopia, and they are related to refractive errors. Therefore, it is obviously wrong to think that refractive examination is a matter of optometrist or optician, rather than ophthalmologist’s own job.
