Does any one know why it occurs? is it purely genetic, or do environmental factors have an effect?
Answers:
Coloboma is a defect arising from improper fusion of the layers in the developing eye. It can affect the eyelid, iris, choroid, retina, optic disc or the lens of the eye.
A similar defect can also occur as a result of injury or eye surgery - but coloboma is a congenital malformation.
