What are the symptoms of a coloboma?

If your child has symptoms from their coloboma, they can include:

• Low vision.
• A keyhole or cat-eye-shaped pupil.
• Blindness or partial vision loss.
• Light sensitivity.
• Nystagmus.

A coloboma might only affect a portion of your child’s field of vision (the full range of how much they can see). Colobomas can cause:

• Reduced peripheral vision.
• Difficulty with depth perception.
• A larger than usual blind spot.
