What are the different types of strabismus?

Strabismus is typically identified or named according to the direction in which the eyes are misaligned. If one eye or both eyes are turned inward – more commonly described as being “cross-eyed,” the medical term is esotropia, sometimes also called being “wall-eyed.” Strabismus can also be a result of vertical misalignment of the eyes. Hypertropia is defined as when the abnormal eye is higher than the normal eye, and hypotropia is when the abnormal eye is lower than the normal eye.
