Amblyopia is an eye condition that develops in children (that can also be present in adults) in which the vision in one eye is weaker than in the other. This occurs in the absence of evident ocular (eye) abnormalities that usually can explain the poor vision. Because amblyopia can have serious, permanent effects on your child, it is important that he or she have regular vision tests. The most common cause of amblyopia is a significant difference between the focusing powers of the two eyes. For example, one eye may be very farsighted while the other one is not, or one eye has a lot of astigmatism (vision is blurred because the eye has an irregular shape), and the other eye does not.
There are several types of treatment for amblyopia. They need to be started as soon as possible after diagnosis, and when the child is young. Eye drops: In cases of mild amblyopia, the doctor might recommend using an eye drop called atropine in the “good” eye instead of a patch. Atropine blurs near vision by dilating the eye, which makes it impossible for that eye to focus close up. This forces the “bad” eye to do most of the work while the child is playing with toys, eating, drawing, or reading..
Amblyopia often starts before there is any obvious sign that something is wrong. This is why babies and young children need to have their eyes checked at regularly scheduled appointments with the doctor.The American Academy of Ophthalmology recommends that children have eye examinations at the following times:
