Decreased pupillary light reflex is a medical symptom characterized by reduced pupil constriction when exposed to light. It typically starts with a decrease in the size of the pupil when exposed to light, followed by a slower-than-normal return to its original size. It may also be accompanied by a diminished response to accommodation or convergence. In severe cases, the pupil may not respond to light at all. Possible causes of decreased pupillary light reflex include trauma, drug effects, and neurological diseases.
