Some babies are born blind or with severe vision loss from birth.

(a) Abnormalities in the development of the eye.
(b) Injury to the eye structures due to prematurity related retinopathy or by developmental problems.
(c) Injury to the parts of the brain responsible for vision.
(d) Genetic or metabolic diseases.
