What does the PERL mnemonic describe when evaluating the eyes?

• A. Pupils Equal Round and Reactive to Light
• B. Pupils Equal Round Reactive to Light
• C. Pupils Equal Round and React to Light
• D. Pupils Equal Round Reactive to Darkness

Answer: (A)

PERL describes the pupillary exam: Pupils Equal, Round, and Reactive to Light. This quick test checks the pupillary light reflex, which relies on a healthy retina and optic nerve (afferent pathway) to sense light, and a functioning oculomotor nerve with the iris sphincter (efferent pathway) to constrict the pupil. When light is shone, both pupils should constrict promptly and appear equal in size. If one pupil is larger (anisocoria) or fails to constrict, it suggests possible neurological or ocular pathology, such as nerve palsy, optic nerve issues, or intracranial problems. The phrasing you’re looking for aligns with Pupils Equal, Round, and Reactive to Light.
