We have obtained the difference spectrum for the macular pigment by comparing the spectral sensitivity of the "green-sensitive" or G cone mechanism in the foveal and parafoveal region. The method overcomes objections to previous attempts to obtain a difference spectrum from the spectral sensitivities by isolating a single receptor mechanism; it also provides a relatively easy approach for obtaining a reliable measure of the optical density of the macular pigment for individual subjects. Our results using this method suggest a higher optical density for the macular pigment than that obtained from data where more than one cone type influenced the difference spectrum.
我们通过比较中央凹和中央凹旁区域“绿色敏感”或G视锥细胞机制的光谱敏感度，获得了黄斑色素的差异光谱。该方法克服了以往通过分离单一受体机制从光谱敏感度中获取差异光谱的尝试所存在的问题；它还为获得个体受试者黄斑色素光密度的可靠测量提供了一种相对简单的方法。我们使用这种方法得到的结果表明，黄斑色素的光密度高于从受不止一种视锥细胞类型影响差异光谱的数据中获得的光密度。
