There is no treatment for the visual impairment caused by coloboma at present.

Failure of this fissure to close results in coloboma iridis.

Other conditions can be associated with a coloboma.

Some have a gap or split in the colored part of the eye (iris coloboma).

A coloboma can occur in one eye (unilateral) or both eyes (bilateral).

Most cases of coloboma affect only the iris.

People with coloboma may have no vision problems or may be blind, depending on severity.

The nerve head typically resembles the morning glory anomaly, but has also been described as a coloboma.

The informant said that the girl she had seen had the same coloboma of the iris as Madeleine.

Eye abnormalities: Cataract, coloboma of the iris and asymmetric pupils.

Eye problems may include coloboma, microcornea, and glaucoma.

Mutations in Pax2 have been identified in half of renal coloboma syndrome victims.

The effects a coloboma has on the vision can be mild or more severe depending on the size and location of the gap.

Other ocular malformations that include coloboma, or are related to it, are:

It is also known as "amelia cleft lip palate hydrocephalus iris coloboma".

He also stated that they should not have publicised the coloboma in her right eye which he claimed put the life of the girl at risk.

The ocular abnormalities are generally retinal coloboma and nystagmus.

A coloboma, or hole, may form in or near the optic disc due to a failed closure of embryonic tissue.

Unilateral or bilateral iris coloboma (absence of tissue from the colored part of the eyes)

The coloboma which occurs often in facial clefts is a cleft in the lower or upper eyelid.

This feature consists of partial absence of ocular tissue (coloboma), often affecting both eyes (bilateral).

Disorders of the eye include myopia, nystagmus, coloboma, microphthalmus, or optic nerve hypoplasia.

The most common orbital /eye anomalies seen in children with facial clefts are coloboma's and vertical dystopia.

Despite the similarities with coloboma and morning glory anomaly, significant differences exist such that optic disc dysplasia cannot be classified as either one entity.

Dysgenesis of the vesicle later in development may result in coloboma, a separate and less severe malformation of the ocular structures.
