Coloboma is a relatively rare congenital condition where tissue in or around the eye is missing. The condition is present from birth because it occurs when the eye develops in the womb during the first three months of growth.
Coloboma can occur in one or both eyes (bilateral coloboma), and there are different types of the condition because different parts of the eye’s structure can be impacted.
The type of coloboma will influence the extent of vision loss and what treatments are available. Not all forms of coloboma cause sight loss, but if it does impact your vision and you’re registered as sight impaired, then support is available. You can find more information on the causes, symptoms, and treatments on the NHS’ coloboma page.
