Pupillary is an adjective that pertains to the pupil of an eye, specifically referring to its size, shape, or related characteristics. It is derived from the word "pupil," which refers to the circular, black opening in the center of the iris that regulates the amount of light entering the eye.
In the context of ophthalmology and optometry, pupillary usually describes anything pertaining to the function or condition of the pupil. For example, pupilary dilation refers to the widening of the pupil, which occurs in low light conditions or as a response to certain medications or stimuli. On the other hand, pupillary constriction signifies the narrowing of the pupil, commonly observed in bright light or in response to certain medications or signals from the autonomic nervous system.
The term pupillary reflex is used to describe the involuntary response of the pupils to changes in light intensity. When exposed to bright light, the normal pupillary reflex causes the pupils to constrict, protecting the eyes from being overwhelmed by excessive light. Conversely, in dim lighting or darkness, the pupils dilate to allow as much light as possible to enter the eye for improved vision.
In summary, pupillary is an adjective that primarily pertains to the characteristics, function, and reflexes of the pupil, the aperture through which light enters the eye.
