PURPOSE
To investigate the possibility of assessing pupil perimetry by evaluating pupil constriction in association with age in healthy persons.
SUBJECTS AND METHODS
A total of 90 healthy persons, aged 18 to 59 years, were enrolled in this study. The percentage of pupil constriction for each of the 76 points was evaluated, in addition to which pupil constriction for 4 specific areas within the total 76 points (center 16, middle 20, peripheral 24, and most peripheral 16) were also studied.
RESULTS
Percentage of pupil constriction at each point was approximately 25%. Pupil miosis has hardly changed with age. There was, however, a steep decline in the percentage of pupil constriction from the center to the periphery of the pupil field.
CONCLUSIONS
The current study demonstrates that standard values can be obtained using pupil perimetry. Additional studies are needed to evaluate the specificity and sensitivity of this technique.
目的
通过评估健康人群中与年龄相关的瞳孔收缩情况来研究评估瞳孔视野计的可能性。
对象与方法
本研究共纳入90名年龄在18至59岁的健康人。评估了76个点中每个点的瞳孔收缩百分比，此外还研究了76个点中4个特定区域（中心16个、中间20个、周边24个和最周边16个）的瞳孔收缩情况。
结果
每个点的瞳孔收缩百分比约为25%。瞳孔缩小几乎没有随年龄变化。然而，从瞳孔视野的中心到周边，瞳孔收缩百分比急剧下降。
结论
当前研究表明，使用瞳孔视野计可获得标准值。需要进一步研究来评估该技术的特异性和敏感性。
