Iris Colobomas (IC) are a cleft in the iris of the eye and will impair vision if large.
A dog with an iris coloboma this large may misjudge distances.
A large coloboma of the iris can inhibit its natural contraction in response to bright light, causing the dog to squint the affected eye.
In many cases the effect on vision is minimal; however a large coloboma can force a dog to squint in bright light because the iris is incapable of contracting to reduce the amount of light entering the eye.
