Premature babies are at greater risk from visual impairment, as has been highlighted by a recent case in India.
Shilpa Hertzberg, from Khar, gave birth to a child named Aron three months before her delivery date and the boy was subsequently diagnosed with retinopathy of prematurity, Daily News & Analysis reported.
She told the news provider: "It was the first time we had heard of it. Our paediatrician explained it to us and referred us to an ophthalmic surgeon."
The condition can cause potential blindness and commonly affects prematurely born babies, but fortunately Aron now has normal vision following five sessions of treatment.
Ms Hertzberg noted that her son will need regular check-ups and may have to wear glasses, or contact lenses, in the future.
At the other end of the age spectrum, a recent study from the University of Michigan Health System found that elderly people who do not get their visual disorders treated are more likely to develop dementia.
