Coloboma usually refers to defects in the bovine iris, but can also apply to defects within the lens or retina.
The disease has also been associated with other congenital defects such as hydrocephalus.
There is no specific treatment for this disease and affected cattle with only one affected eye may be salvaged but should be removed from the breeding herd.
