Abstract
We investigated the gender effects on transient pupillary light reflex (PLR) in healthy young adults between 18 and 22 years old. Both dark-adapted and light-adapted PLRs were measured using green and red stimuli of different intensities. The results indicate that females had significantly larger relative constriction amplitudes than males in a dark-adapted condition. This gender effect depends on the stimulus intensities. The relative constriction amplitude in female subjects increased faster than it did in the males with the stimulus intensity. We did not observe any significant gender differences in the other PLR parameters, including latency, constriction speed, and recovery speed.
