Amblyopia (lazy eye) in children

Amblyopia, also called "lazy eye", is reduced vision in one eye that develops during childhood: even with glasses, that eye sees less well than the other. It affects about 2-3 children in 100, and parents often do not notice, because the child sees well with the other eye and does not complain.

Why it develops

In the first years of life the brain “learns” to see. If one eye sends blurred images, or images different from the other eye, the brain tends to use it less and less. The most common causes are:

• A significant vision problem in one eye only, or very different between the two eyes (for example high hyperopia or astigmatism)
• Strabismus, where the eyes do not look in the same direction

Why it is important to detect it early

The earlier amblyopia is detected, the better it can be treated: the best results are achieved in the first years of life, while after the age of 6-7 recovery becomes more difficult. That is why it is important to:

• have your child seen by an ophthalmologist in the first years of life and then regularly;
• not wait for the child to complain: they often do not realise they see less with one eye.

A simple test at home: cover one of your child's eyes at a time while they look at something. If they protest, fidget or try to push your hand away only when you cover one of the two eyes, talk to the ophthalmologist.

How it is treated

The diagnosis and treatment of amblyopia are the responsibility of the ophthalmologist, often together with the orthoptist. Treatment usually involves:

• correcting the vision problem with glasses;
• when needed, occlusion (patching) of the better-seeing eye, on a schedule decided by the ophthalmologist.

At Ottica Paoletti we make the prescribed glasses, suited to children in size, lightness and durability, and we help you choose them together with your child.
