Amblyopia
Good vision develops during childhood when both eyes are normally aligned. Strabismus may cause reduced vision, or
amblyopia, in the weaker eye. The brain will recognize the image of the better-seeing eye and ignore the image of the weaker or amblyopic eye. This occurs in approximately half the children who have strabismus.
Amblyopia can be treated by patching the "good" eye to strengthen and improve vision in the weaker eye. If amblyopia is detected in the first few years of life, treatment is usually successful. If treatment is delayed, amblyopia can become permanent. As a rule, the earlier it is treated, the better the chances of saving vision.
