DIOPTRON自動驗光儀之臨床評估
Clinical Evaluation of the Dioptron Auto-Refractor
摘要
由門診取樣142個病人，260隻眼睛，分別以Dioptron及Retinoscopy做屈光檢查，將結果分成正視、遠視及近視三組加以分析比較，發現在球鏡相當屈光度方面(Spherical equivalent refraction)，正視這一組對兩種屈光方法在統計上沒有差異，在遠視及近視兩組，Dioptron較Retinoscopy為高估，尤其在近視這一組隨著屈光度的增加，兩者差值有增大之趨勢。

There were 142 patients (260 eyes) undergoing refraction separately by the Dioptron and retinoscopy. The result was then divided into three groups, namely emmetropia, hyperopia and myopia. The results of two methods were compared statistically. There was no significant difference of the spherical equivalent refraction between the Dioptron and retinoscopy in emmetropic group, but the Dioptron overestimated the spherical equivalent refraction in myopic and hyperopic groups. The Dioptron was easy to operate, rapid processing and proved to have clinical value especially in massive screenings, but effectiveness of the machine was limited by 1. inability to detect small pupil size patients, 2. poor cooperative subjects (i.e.: elderly, small children and patient with nystagmus or strabismus), and 3. refractive error more than +15.00 D or -10.00 D.
