Miosis refers to which pupil finding?

Explanation:
Miosis is a constricted pupil—the pupil becomes small and may react to light. It reflects parasympathetic influence causing narrowing. This is the opposite of dilation (mydriasis), while ptosis is drooping of the eyelid and anisocoria means the pupils are unequal in size. So the term that describes a small, constricted pupil is miosis.
