WHAT IS A in Perrla?

To document the findings of a pupillary examination, many students and doctors use PERRLA, which stands for: Pupils Equal, Round, Reactive to Light and Accommodation.

What are normal Perrla findings?

Round: Healthy pupils are round. If the shape of the pupils is unusual, this could signify an injury to the eye. Reactive to light and accommodation: Healthy pupils get smaller in bright or direct light, as well as when a person focuses on something very close to their eyes.

Pupillary assessment is an important part of neurological assessment because changes in the size, equality and reactivity of the pupils can provide vital diagnostic information in the critically ill patient (Smith, 2003). Both pupils should be the same shape, size and react equally to light.
