A new method was developed to measure spectrally and spatially resolved cone pigment optical density difference in normal human subjects. Using digitized television images of human retinas scanned before and after bleaching the cone pigments with a bright light, unique high-resolution images of cone pigment density difference were produced. The spectral peak density difference within the fovea was found to be at 560 nm. These measurements demonstrate a decrease in cone pigment optical density difference with increased distance from the subject's central fixation point in the fovea. The cone pigment density difference was asymmetrically distributed in the fovea with higher amounts on the nasal side.
一种新方法被开发出来用于测量正常人类受试者中光谱和空间分辨的视锥色素光密度差异。利用在强光漂白视锥色素前后扫描的人类视网膜数字化电视图像，生成了视锥色素密度差异的独特高分辨率图像。发现中央凹内的光谱峰值密度差异在560纳米处。这些测量结果表明，在中央凹中，随着与受试者中央注视点距离的增加，视锥色素光密度差异减小。视锥色素密度差异在中央凹中呈不对称分布，鼻侧的量更高。
