Important causes of blindness in two eyes
There are many causes of blindness. Three important ones are:
Cataract
This is the cause in 20% of cases where children are affected. A cataract is a clouding of the lens inside the eye. In children it may be due to hereditary causes, or due to infections like rubella during pregnancy. Whatever the initial cause, blindness due to cataracts can be prevented by early detection and treatment.
Retinopathy of prematurity
This is the cause in 20% of cases affecting children. Retinopathy of prematurity is the scarring of the retina at the back of the eye that may occur when high levels of oxygen are administered to premature babies. Blindness due to retinopathy of prematurity can be prevented by early detection and treatment.
Corneal scarring
This is the cause in 10% of cases affecting children. Corneal scarring refers to scarring of the window in the front of the eye. It may be due to infections, Vitamin A deficiency, and the use of harmful traditional eye medicines. Blindness due to corneal scarring can be prevented by early detection and treatment.
Important causes of blindness in one eye
Injuries
These can result from accidents caused by a variety of objects, such as sticks, stones, BB pellets and fireworks. Children should be discouraged from playing with items like these.
“Lazy eye”
This may occur where children have a squint (when eyes are not straight), or sometimes if the child needs glasses. If neglected, this condition cannot be treated.
How to prevent childhood blindness?
- No sticks, stones, BB gun pellets and fireworks
- No harmful traditional eye medicines
- Ensure good nutrition and face hygiene
If you think your child has a vision problem, don’t delay, get their eyes tested by a professional.
