What does PERRL stand for in eye examination?

The term PERRL stands for "Pupils equal, round, and reactive to light." This acronym is commonly used in medical examinations to quickly assess the state of a patient's pupils, which can provide important information regarding neurological function and eye health.

In this phrase:

• "Pupils" refers to the openings in the center of the eyes that allow light to enter.

• "Equal" indicates that both pupils should be of similar size—a sign of normal function.

• "Round" means the shape of the pupils should be circular, which is typical in healthy eyes.

• "Reactive to light" indicates that the pupils constrict in response to light exposure, demonstrating a normal reflexive action.

Together, this assessment can help healthcare professionals evaluate the neurological status of a patient, as abnormalities in pupil size, shape, or reactivity can indicate underlying health issues.
