What are Changes in Pupils?

The pupils are the black circular openings in the center of the eyes that regulate the amount of light entering the eye. Changes in pupil size, shape, symmetry, or reaction to light can sometimes indicate serious neurological conditions.

After head trauma, unequal pupils or sluggish pupil reactions may suggest increased pressure inside the skull or injury to important brain structures.
