1. Amblyopia
HCT II

2. Lazy eye (amblyopia) is decreased vision that results from abnormal visual development in infancy and early childhood
Lazy eye develops when nerve pathways between the brain and the eye aren't properly stimulated. As a result, the brain favors one eye, usually due to poor vision in the other eye. The weaker eye tends to wander. Eventually, the brain may ignore the signals received from the weaker — or lazy — eye.

3. Signs and symptoms of lazy eye include:

Eyes that may not appear to work together
Poor depth perception

Eye patches. To stimulate the weaker eye, your child may wear an eye patch over the stronger eye.
Eyedrops. A daily or twice-weekly drop of a drug called atropine can temporarily blur vision in the stronger eye. This will encourage your child to use his or her weaker eye, and offers an alternative to wearing a patch.
Surgery. If your child's eyes cross or wander apart, your doctor may recommend surgical repair for the eye muscles.
