Question
What to Do If an Eye Injury Causes Pupil Dilation?
Answer
Pupil dilation caused by an eye injury is due to nerve damage that controls the pupil’s sphincter muscle. If there is no obvious vision abnormality, this condition does not require treatment. With pupil dilation, most patients will experience photophobia again under bright light, and wearing colored glasses under bright light can prevent the symptoms of photophobia. Pupil dilation has no direct correlation with the retina in general.
