OSCAR Color Vision Testerによる色覚検査成績

Test results of OSCAR color vision tester

（1）今回我々はOSCARを用いて先天性色覚異常者83名に検査を行い，その結果を他の検査方法と比較した．

（2）本器による分類はAnomaloscopeの成績と良く一致したが，木器を用いて程度判定を正確に行うことは困難であった．

（3）本器は他の色覚検査法の結果とも良く一致し，しかも操作が容易なため，幼小児に対しても検査を行うことができた．

We examined 83 subjects with congenital color vision defects using OSCAR (objective screeningcolor anomalies and reduction) color vision tester developed by Estevez (1983). The findings were compared with those by anomaloscope and pseudo-isochromatic color plates, Examinations by OSCAR allowed the classification of color vision defects into protan and deutans at a fair degree of accuracy comparable with anomaloscope. It gave poor results in estimating the degree of color vision defect.Because of the ease of operation, the device could be used by infants of 4 years or more in our pre-sent series. These features seem to be excellent fe-atures of the OSCAR system.
