Amblyopia, also known as lazy eye, may result from poor alignment of the eyes as occurs in strabismus, or from a significant imbalance in the refractive powers of the eyes. When amblyopia is untreated, the brain favors the image received from the eye that sees better and ignores the blurred image of the misaligned or out-of-focus eye. Amblyopia can be treated successfully when detected early. If treatment is delayed until the later years, loss of vision can result in the eye that is not being used.
Principal symptom: an eye that is misaligned; other indications: tilting the head in a specific direction in an attempt to align the eyes, squinting one eye, bumping into objects or other signs of faulty depth perception, double vision
Covering or patching the good eye, glasses, eye drops, exercises or a combination of these approaches
