What does the acronym PERRLA stand for?

• A. Pupils Equal, Round, Reactive to Light and Accommodation
• B. Pupils Equal, Relative to Light and Accommodation
• C. Pupils Equal, Round, Reactive to Light and Axes
• D. Pupils Equal, Round, Reactive to Light and Anisocoria

Answer: (A)

PERRLA encodes four features checked in a pupil exam: Pupils Equal, Round, Reactive to Light and Accommodation. Pupils equal means the two pupils are the same size, which rules out anisocoria. Round describes the typical circular shape of the pupils. Reactive to Light means the pupils constrict in response to light (the direct reflex) and also constrict when the other eye is exposed to light (the consensual reflex), reflecting intact sensory and motor pathways. Accommodation refers to the near reflex—pupils constrict when focusing on a close object, along with convergence of the eyes. Together, PERRLA represents a normal, symmetric, reactive pupil exam.
