Pupillary reaction refers to the change in the size of the pupil in response to various stimuli. The pupil is the opening in the center of the iris that allows light to enter the eye. The size of the pupil is regulated by the muscles in the iris, which are controlled by the autonomic nervous system. Pupillary reactions can be either direct or consensual. Direct reactions occur when the stimulus affects the eye directly, such as changes in light intensity. Consensual reactions occur when the stimulus affects both eyes simultaneously, such as in the case of a bright light shining into one eye.
Pupillary reactions are important for visual function and are influenced by several factors, including age, health
Pupillary reactions are typically assessed using a device called a pupillometer, which measures the size of
