What does the PERRL acronym represent in a pupil examination?

The acronym PERRL stands for "Pupils Equal, Round, and Reactive to Light." This phrase is a standard shorthand used during pupil examinations to assess the condition of a patient’s eyes. When healthcare providers refer to pupils as equal, it indicates that both pupils are the same size. When they describe them as round, it signifies the normal shape of the pupils. Being reactive to light means that the pupils constrict (become smaller) when exposed to light, which is a sign of proper neurological function.

This examination provides essential information about the functioning of the nervous system, particularly the pathways involved in vision and the autonomic response to light. Observing these characteristics helps healthcare professionals determine whether there are any abnormalities present that may require further investigation.
