We photographed the pupils of 128 normal subjects in dim light, morning and afternoon, for five consecutive days. Fifty-two of the subjects (41%) had an anisocoria of 0.4 mm or more at one time or another during these five days, but only four (3%) had unequal pupils of 0.4 mm or more in all ten photography sessions. At any given examination, a fairly constant 19% (24 of 128) of the subjects showed this amount of anisocoria. These numbers shifted dramatically when anisocoria was defined as a pupillary inequality of greater than, or less than, 0.4 mm. The prevalence of anisocoria did not vary with the time of day, from day to day, or from week to week, nor was it influenced by the sex, age, or iris color of the subject.
我们在暗光下对128名正常受试者的瞳孔进行了拍摄，分别在上午和下午连续五天进行。在这五天里，52名受试者（41%）曾在某个时间出现瞳孔不等大达0.4毫米或以上的情况，但在全部十次拍摄中，只有四名（3%）受试者的瞳孔不等大达到0.4毫米或以上。在任何一次特定检查中，相当稳定的19%（128名中的24名）受试者表现出这种程度的瞳孔不等大。当瞳孔不等大被定义为瞳孔差异大于或小于0.4毫米时，这些数字发生了显著变化。瞳孔不等大的患病率并不随一天中的时间、日复一日或周复一周而变化，也不受受试者的性别、年龄或虹膜颜色影响。
