目的 探讨对色觉进行定量测定。方法 采用自行研制的色觉定量测定仪,对用假同色色盲表检查为正常色觉者1000例(2000只眼);红绿色盲,红、绿色弱各30例(60只限)进行色觉定性与定量测定。结果 正常者:红色值为3.44±0.52,绿色值3.93±2.06;红绿色盲者:红色值78.5±9.69,绿色值89.0±6.23;红色弱者:红色值39.40±7.62;绿色弱者,绿色值43.60±11.25。结论 本测定法对正常色觉与色觉异常既能定性又能定量测定,优于假同色色盲表检查法。
Objective To explore the quantitative determination of color vision. Methods 1000 patients (2000 eyes) with normal color vision were detected by the same color blindness test, and 30 cases (60 eyes) of red-green color blindness, redness and green weakness were detected qualitatively and quantitatively Determination. The results were normal: the red value of 3.44 ± 0.52, the green value of 3.93 ± 2.06; red and green blind: the red value of 78.5 ± 9.69, the green value of 89.0 ± 6.23; red and weak: the red value of 39.40 ± 7.62; green weak, the green value of 43.60 ± 11.25 . Conclusions This method can not only qualitatively and quantitatively determine the normal color vision and color vision abnormalities, but also surpass the false color blindness test.
