Amblyopia (Lazy Eye)
Amblyopia also known as a lazy eye has several causes. One common cause occurs when one eye has a much higher prescription or a different amount of myopia, hyperopia or astigmatism then the other eye. This causes the eye with the higher refractive error to suppress while the other eye does all the work for the visual system. This results in the eye not forming the proper neural connections with the brain. Amblyopia can be treated if caught early enough in childhood by glasses, patching or drops and vision therapy. If left untreated, amblyopia will lead to permanent visual problems and decreased depth perception.
Strabismus (Crossed Eye)
Strabismus occurs when the eye muscles are too weak and the eyes cannot maintain focus on an object together. Often one eye will turn in or out or both eyes will turn in or out. Strabismus can be corrected by ocular surgery.
