Strabismus is a heterogenous group of conditions characterized by the misalignment of the eyes. It may manifest as constant or intermittent deviation, meaning the eyes sometimes appear well aligned, or straight, and sometimes appear misaligned. Vision can be normal in some patients, but when associated with amblyopia, may be decreased vision in one eye. There is sometimes diminished binocular vision, with decreased depth perception.
