A cat eye is a type of coloboma. Any defect in the iris that allows
light to enter the eye, other than through the pupil, is called a
coloboma. An extra hole or slit may be present from birth, or may
result from trauma. Colobomas may also exist in the eyelid, a
defect which interrupts the border of the eyelid.
