Coloboma

What is it?

A condition from birth where one has tissues missing from their eye and can makes one eye appear different, it does not always affect one vision.

Coloboma can affect different parts of the eye:

Iris:

  • The iris is a round, disk-shaped muscle with a hole in the middle where the pupil is located, here it appears like  a keyhole or cat-eye appearance of the pupil.
  • Coloboma  can affect the sensitivity of light and thus cause blurred vision

Retina:

  • Specialized tissue that lines the back of the eye, the retina senses light and creates electrical impulses which are sent to the brain via the optic nerve.
  • Coloboma  can affect the sensitivity of light and thus cause blurred vision

Microphthalmia (small eye)

  • Often linked with very large colobomas of the retina.

Choroid: 

  • The blood vessel layer of the eye, located between the retina and the sclera (the white outer coat that surrounds the iris)

Optic nerve:

  • A bundle of over a million nerve fibres that carry visual messages from the retina to the brain.
  • Coloboma of the optic nerve often causes blurry vision and blind spots.
