The variation of the colour of the optic disc was examined with a slit lamp and contact lens in 200 normal subjects simply by moving the image of the slit across the optic disc. This event was photographed in 15 subjects and colour densitometry was performed. The temporal part of the pale central excavation changes colour to red, when illuminated nasally and vice versa. The colour change could not be provoked in subjects with normal discs with flattening of the temporal disc sector. The whole neurorim reddens the whole way round when the slit hits the optic disc border, and dependent on fundus pigmentation slight redness was produced even when the slit was placed outside the disc in the neighbourhood of the border.
在200名正常受试者中，使用裂隙灯和接触镜，通过将裂隙图像移动到视盘上来检查视盘颜色的变化。对15名受试者进行了该过程的拍照，并进行了颜色密度测定。苍白中央凹陷的颞侧部分在鼻侧照明时会变为红色，反之亦然。在颞侧视盘扇形变平的正常视盘受试者中，无法诱发颜色变化。当裂隙碰到视盘边界时，整个神经 rim 会全程变红，并且根据眼底色素沉着情况，即使裂隙位于视盘边界附近的视盘外，也会产生轻微的红色。
