ABSTRACT
PURPOSE:
To determine the normal ranges of various indexes of the pupillary light reflex measured by automated pupillometry in Koreans.METHODS:
We retrospectively analyzed 90 healthy adults who did not have any ocular diseases other than refractive errors. The direct pupillary light reflex was measured with an automated dynamic pupillometer (PLR-200, NeurOptics Inc., Irvine, CA, USA). A total of 7 indices were measured as follows; the maximum and minimum pupil diameters, constriction latency, constriction ratio, maximum constriction velocity, average constriction velocity and average dilation velocity.RESULTS:
There were no significant differences in quantitative indexes of the pupillary light reflex between fellow eyes. A significant decrease in maximum pupil diameter, minimum pupil diameter, maximum constriction velocity, average constriction velocity and average dilation velocity were observed with aging. In contrast, a significant increase in constriction latency was observed with aging. There were no differences in quantitative pupil measurements according to gender (p<0.001).CONCLUSIONS:
Quantitative measurements of the pupillary light reflex by dynamic pupillometry showed no significant differences between fellow eyes. A significant decrease in pupil size, constriction velocity and dilation velocity, and an increase in pupil constriction latency were observed with aging.
