抄録

Using binocular Iriscorder the pupillary reflex to the light was analyzed in 49 healthy, normal subjects and normal values of 10 factors of direct and indirect pupillary reactions were determined.<br>The above-mentioned normal values were further discussed, with regard to several factors, such as age, duration of stimulation and state of adaptation of the pupil to the light.<br>From a series of examinations, the following facts were noted:<br>(1) No significant differences between the direct and indirect pupillary reactions were observed, with regard to 9 factors of the light reflex, with the exception of pupil dilatation time.<br>(2) It was found that the longer the duration of stimulation, the stronger the contraction, and the dilatation phases of the light reflex were more marked in dark adaptation than in light adaptation.<br>(3) It was also found that in aged people, the activity of the pupil was under adrenolytic and/or cholinergic conditions.
