Patient's question:
Generally, pupils only dilate at night, but after a single eye injury, the pupil may also unconsciously enlarge, looking quite unsettling. What should be done if pupil dilation is caused by an eye injury? What are the potential consequences? Will the retina also dilate along with it?Doctor's answer:
Eye trauma can cause pupil dilation, which is usually caused by damage to the nerves that control the pupil sphincter. If there are no significant vision abnormalities, treatment may not be necessary. Dilated pupils often cause photophobia in patients under bright light, and wearing colored glasses in bright light can help prevent this symptom. Pupil dilation is generally not directly related to the retina.
