PURPOSE
To study the relationship between pupil size and light intensity using the Procyon pupillometer.
SETTING
University based clinic.
METHODS
In this retrospective study, 20 consecutive patients had pupil size assessment with the Procyon pupillometer under 3 different light conditions--4, 0.4, and 0.04 lux. Correlation was established using the log unit of the light intensity and pupil size.
RESULTS
The correlation coefficient for the association between pupil size and log unit of light intensity in all eyes was significant (P<.001). The mean correlation coefficient for the association between pupil size and log unit of light intensity in all patients was 0.968 +/- 0.089 (SD) in the right eye and 0.970 +/- 0.031 in the left eye.
CONCLUSION
The linear relationship between the pupil size and the log unit of the light intensity showed a tight correlation in all cases. These results can be useful in the comparing pupil size with pupillometers that work under different light conditions.
目的
使用Procyon瞳孔计研究瞳孔大小与光强度之间的关系。
地点
大学附属医院。
方法
在这项回顾性研究中，连续20例患者在3种不同光照条件下（4、0.4和0.04勒克斯）使用Procyon瞳孔计进行瞳孔大小评估。使用光强度和瞳孔大小的对数单位建立相关性。
结果
所有眼睛中瞳孔大小与光强度对数单位之间的关联的相关系数具有显著性（P<0.001）。所有患者右眼瞳孔大小与光强度对数单位之间关联的平均相关系数为0.968±0.089（标准差），左眼为0.970±0.031。
结论
瞳孔大小与光强度对数单位之间的线性关系在所有情况下均显示出紧密的相关性。这些结果对于比较在不同光照条件下工作的瞳孔计的瞳孔大小可能有用。
