Why does my child have a coloboma?
Some children are born with a key-hole shaped rather than a round pupil – the technical term for this is coloboma. Usually, the elongated part of the pupil is at the bottom part of the iris, towards the nose. A coloboma is the result of an incomplete development of that particular part of the eye. Renowned consultant ophthalmologist Dr Annegret Dahlmann-Noor details information for parents and carers.
