What is Coloboma

Coloboma is a congenital eye abnormality that affects the structure of the eye. It occurs when there is incomplete development of certain eye tissues during fetal development. This results in a gap or a notch in one or more parts of the eye, such as the iris, retina, choroid, or optic disc.

Coloboma can vary in size and location, leading to different visual impairments. The most common type is iris coloboma, where there is a missing piece in the colored part of the eye. This can cause sensitivity to light and blurred vision. Retinal coloboma affects the retina, leading to reduced visual acuity and potential vision loss.

Coloboma can occur in one or both eyes and may be associated with other eye or systemic conditions. It is typically diagnosed during infancy or childhood through a comprehensive eye examination. While there is no cure for coloboma, treatment focuses on managing associated symptoms and optimizing visual function through corrective lenses, low vision aids, or surgery in some cases.
