What Is PERRLA Eye

The pupillary light reflex, or PERRLA, is a medical test that assesses the pupillary response to light. The test is performed by shining a light into the eye and observing the pupil's reaction.

The PERRLA test is commonly used to assess for:

* Neurological damage: The PERRLA test can help identify damage to the optic nerve, the brain, or the spinal cord.

* Eye disorders: The PERRLA test can help identify eye disorders, such as glaucoma, uveitis, and retinal detachment.

* Drug use: The PERRLA test can help identify drug use, such as opioid overdose.

The PERRLA test is a simple and non-invasive test that can provide valuable information about the neurological and ocular health of a patient.

Here are the steps on how to perform the PERRLA test:

1. Ask the patient to look straight ahead.

2. Shine a bright light into the patient's eye for about 3 seconds.

3. Observe the pupil's reaction.

The normal pupillary response to light is for the pupils to constrict (get smaller). If the pupils do not constrict, this may be a sign of a neurological or eye disorder.

The PERRLA test is a useful tool for assessing for neurological damage, eye disorders, and drug use. If you have any concerns about your vision or neurological health, talk to your doctor about getting a PERRLA test.
