why some people are blind by birth
Asked by Kavita | 20th Dec, 2015, 01:58: PM
Some babies are born blind or with severe vision loss from birth.
This can be caused due to various factors like:
(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.
(e) Defects or abnormalities in the eye itself (like coloboma, glaucoma, cataract).
(f) Infections by viruses such as cytomegalovirus (CMV).
