Because of cataracts, a neighbor was deprived of visual experiences during early childhood. last year, her vision was restored by surgery but she is having difficulty in dealing with the visual world. this is probably because

brain cells normally devoted to vision died or were diverted to other uses

Explanation:

The term “cataract” is given to any type of lens transparency loss, a lens located behind the iris, whether congenital or acquired, regardless of whether or not it causes vision damage. According to the World Health Organization (WHO), cataract is responsible for 47.8% of blindness cases in the world, affecting mainly the elderly population.

Congenital cataract arises in children since birth in children and can be reversed by surgery. The sooner the crirugia is done in children with cataracts, it will be better for the child to see, because people with congenital cataract who have had years to have surgery may have trouble seeing even after the cataract is removed from their body. This is because brain cells normally dedicated to vision may die or be diverted to other uses.
