What is Amblyopia?

Commonly known as “lazy eye”, it is the loss of one’s ability to see details. It is one of the leading causes of vision problem in children.

When the nerve pathway from one eye to the brain does not develop during childhood, it often leads to lazy eye. It is the result of the abnormal eye sending a blurred image or the wrong image to the brain.

What are the symptoms?

Some of the symptoms include
- eyes that turn in or out
- eyes that do not appear to work together
- inability to judge depth correctly
- poor vision

What are the causes of Amblyopia?

1. Refractive Amblyopia:
In this Amblyopia, one eye is more nearsighted or farsighted than the other, making it difficult for the eyes to focus together.  Starting early in life, an infant often has no way of informing parents that he is experiencing poor vision. However once discovered, treatment includes glasses or contacts to help equalize vision in both eyes.
It is often said that Refractive amblyopia is the easiest type of lazy eye to correct.  

2. Strabismic Amblyopia:
Strabismus is referred to as crossed or wandering eye. It is the condition in which the brain is unable to align the eyes properly. When the eyes are not pointing in the same direction, two different pictures are sent to the brain – leading to double vision. To avoid seeing double, the brain shuts off communication from the misaligned eye; leading to stunted development in that eye.

Can vision be completely restored in the child?

If treated early, children usually recover almost normal vision, although they may continue to experience problems with depth perception.
