In this paper it will be shown that the association of pupillary contraction with even substantial accommodation breaks down under rigorous control of alignment. Conditions exclude other than "accommodative" (blur induced) pupillary responses by eliminating light reflexes due to temporal and spatial luminance differences, colour and polarization differences. The visual solid angles of the targets were also precisely equalized. A subtle procedure is described to obtain accurate alignment along a single line of sight of the stimulated eye. The pupillary system appears to be quite sensitive to alignment errors, but the "accommodative pupillary reflex" is totally absent under rigorous alignment. Pupillometry used an infrared television camera to monitor the non-stimulated eye in total darkness and silence. Occurrence of correct accommodation for every stimulus event was confirmed by observing accommodative vergence. Judging by the size of the accommodative vergence response and, occasionally, the size of Purkinje-Sanson images, the accommodative response was found to be essentially equal to the stimulation.
本文将表明，在严格控制眼位对准的情况下，即使是较大程度的调节，瞳孔收缩与之的关联也会瓦解。通过消除因时间和空间亮度差异、颜色和偏振差异引起的光反射，实验条件排除了除“调节性”（模糊诱导）瞳孔反应之外的其他反应。目标的视觉立体角也被精确地均衡化。文中描述了一种精细的程序，以沿着受刺激眼睛的单条视线获得精确的对准。瞳孔系统似乎对对准误差相当敏感，但在严格对准的情况下，“调节性瞳孔反射”完全不存在。瞳孔测量使用红外电视摄像机在完全黑暗和安静的环境中监测未受刺激的眼睛。通过观察调节性聚散来确认每次刺激事件时正确调节的发生。从调节性聚散反应的大小，以及偶尔从普尔钦耶-桑松图像的大小判断，发现调节反应基本等同于刺激。
