PERRL stands for Pupils equal, round, reactive to light, a nursing abbreviation.

Pupil finding used when light reflexes were checked but accommodation was not, which is the usual situation in sedated, confused or critically ill patients who cannot focus on a near target. It is more accurate than PERRLA for most bedside neuro checks.

Example: Hourly neuro checks: GCS 14, PERRL 4 mm brisk, no new deficits.

Usage notes

Many neurologists recommend PERRL over PERRLA unless near response was actually tested. Automated pupillometers can measure size and constriction speed and give a numeric reactivity score. Recording size in millimeters and speed of reaction (brisk, sluggish, fixed) conveys far more than the letters alone.
