PERRLA (pupils equal, round, reactive to light and accommodation)
PERRLA stands for "Pupils Equal, Round, Reactive to Light and Accommodation." It is a simple clinical assessment used by healthcare professionals to check the health of a person's visual and neurological system. During a PERRLA assessment, a doctor or nurse examines the pupils of the eyes to ensure they are equal in size and round in shape. This indicates normal eye function and symmetry.
The examination also involves testing the pupils' reactivity to light to see if they constrict (get smaller) when a light is shone into the eyes. This reaction is vital for determining how the eyes respond to changes in light. Lastly, the accommodation part of the test checks how well the pupils adjust when focusing on objects at different distances, which is important for clear vision.
PERRLA is an essential tool in routine eye exams and can help identify potential issues related to the brain and nervous system. Any abnormal findings may prompt further investigation to diagnose underlying conditions.
