Etiology - Amblyopia (lazy eye) is caused by developmental eyesight challenges that occur early in life. It can often result from strabismus (misaligned eyes) or other similar innate visual imbalances.
Symptoms - Blurry vision in one eye, poor depth perception, a wandering eye (drifting inward or outward), frequent eye rubbing, squinting, and overall difficulty performing visual tasks.
Details - Develops when the brain and eyes are not working properly together. This leads to the brain favoring visual input from one eye over the other, which, if left untreated, can cause abnormal function and limited vision in the less favored eye
Treatment - The best way to treat amblyopia is to force the brain to use and rely on the weaker eye; however, for best long-term outcomes, it is imperative that treatment starts early in life (ideally elementary-aged or younger). Common strategies include corrective lenses, patching of the stronger eye, eye drops limiting the stronger eye's dominance, vision therapy, and even surgical procedures.
