What is PERRLA?

This test is used to check the appearance and function of your pupils. The information can help your doctor diagnose several conditions, from glaucoma to neurological diseases.
PERRLA is an acronym that helps doctors remember what to check for when examining your pupils. It stands for:
•Pupils. The pupils are in the center of the iris, which is the colored part of your eye. They control how much light enters the eye by shrinking and widening.
•Equal. Your pupils should be the same size. If one is larger than the other, your doctor will want to do some additional testing to figure out why.
•Round. Pupils should also be perfectly round, so your doctor will check them for any unusual shapes or uneven borders.
•Reactive to. Your pupils react to your surroundings to control how much light enters your eyes. This step reminds your doctor to check your pupils’ reactions to the next two items in the acronym.
•Light. When your doctor shines a light in your eyes, your pupils should get smaller. If they don’t, there could be a problem affecting your eyes.
To perform a pupillary exam, your doctor will have you sit in a dimly lit room. They’ll start by simply looking at your pupils, noting anything unusual about their size or shape.
Next, they’ll do a swinging eye test. This involves moving a small, hand-held flashlight back and forth between your eyes every two seconds while you look in the distance. They’ll do this several times to see how your pupils react to the light, including whether they react at the same time.

However, one out of five people with no eye health problems have pupils that are normally different sizes. Some examples of conditions that cause differently sized pupils include: •brain injuries, such as a concussion •aneurysm •glaucoma •brain tumor •brain swelling •intracranial hemorrhage •stroke •seizure •migraine

Instead, they give your doctor a better idea of what other tests they can use to help narrow down what might be causing your symptoms.
Pupil eye exams are quick, noninvasive tests that doctors can use to check the health of your eyes and nervous system. PERRLA is the acronym they use to remember exactly what to check when examining your pupils.
