The pupillary light reflex (PLR) is a reflex response when light enters the eye and stimulates the retina. It is measured as the dilation of the pupil in response to light stimulation. 

The PLR is an important reflex because it helps us focus on objects near our eyes. Doctors use the PLR during pupil evaluation to assess whether a patient’s vision is optimal and to determine the cause of any abnormalities. 

By understanding how the PLR works and what indications it provides, doctors can make better decisions about a patient’s care.
