coloboma -

Coloboma is a term that describes the holes found in the structure of the eye, such as the lens of the eye, eyelids, iris, retina, choroid, or optic disc. This hole has been around since birth and can be caused by the distance between the two structures in the eye. This structure fails to close before the baby is born. Coloboma can occur in one or both eyes.

Cloboma affects outlook, depending on the severity according to size and location. For example, if only a small part of the iris is damaged, the view may be normal. However, if it occurs in the retina or optic nerve, then the patient's view will be damaged and most of the field of view will be lost. Sometimes the eye may shrink or microftalmos, and even the patient may suffer from other eye diseases such as glaucoma.

Some children who suffer from coloboma can have malformations on the part of the body, as occurs in CHARGE syndrome.
