Abstract
In 19 normal subjects the pupillary reflex to light was studied over a range of stimulus intensities by infrared electronic pupillography and analysed by a computer technique. Increasing stimulus intensity was associated with an increase in direct light reflex amplitude and maximum rate of constriction and redilatation. Latency from stimulus to onset of response-decreased with increasing stimulus intensity. The normal range for each of these parameters is given and the significance of these results in clinical pupillary assessment discussed.
摘要
在19名正常受试者中，通过红外电子瞳孔描记术在一系列刺激强度范围内研究了瞳孔对光反射，并采用计算机技术进行分析。刺激强度增加与直接光反射幅度、最大收缩率和再扩张率的增加相关。从刺激到反应开始的潜伏期随刺激强度增加而缩短。给出了这些参数各自的正常范围，并讨论了这些结果在临床瞳孔评估中的意义。
