Ocular Examination Abbreviations
PERRLA describes pupils that are equal, round, and reactive to light and accommodation.
EOMI describes extra-ocular movements that are intact.
PERRLA
- Pupils equal: the right and left pupils are of similar size.
- Pupils round: the pupils have a round shape.
- Reactive to light: constriction occurs in response to a light stimulus.
- Reactive to accommodation: constriction and lens accommodation occur when focusing from a distance target to a near target.
EOMI
- Extra-ocular movements intact: eye movements through standard directions of gaze occur without limitation.
- Associated clinical implication: absence of restricted gaze or major ocular motor palsy on exam.
