Strabismus is a condition in which the eyes do not properly align with each other when looking at an object. The eye that is focused on an object can alternate. The condition may be present occasionally or constantly. If present during a large part of childhood, it may result in amblyopia or loss of depth perception. If onset is during adulthood, it is more likely to result in double vision. Strabismus treatment aims to improve the alignment of the eyes and to correct the resulting vision loss (amblyopia). Strabismus and amblyopia can be treated with any one or a combination of glasses, eye patching or surgery.
