- Pupillary response
Pupillary response or dilation of the pupil is a physiological response that varies the size of the
pupil of the eye via theiris dilator muscle . It can have a variety of causes. It may be an involuntary reflex reaction to exposure to light. Or it may indicate interest in the subject of attention or indicate sexual stimulation. [Citation
