Eye Problems: Changes in Your Pupils - Topic Overview

With an injury to the eye, the muscles that control the pupil size and shape can be damaged. These muscles control the ability of the pupil to change in size and keep its round shape.

An injury that punctures the eyeball may tear the colored part (iris) of the eye, causing it to lose its round shape.

Retinitis

Retinitis is a disease that threatens vision by damaging the retina -- the light-sensing tissue at the back of your eye. Although there's no cure, there are steps you can take to protect your sight and make the most of the vision you have.

An injury to the eye may also cause the pupils to react differently to light or to be different sizes.

Call your doctor for an evaluation if you have a change in the size or shape of your pupil after an injury to your eye.
