Accommodative esotropia is a type of strabismus.
Strabismus refers to any misalignment of the eyes. Accommodation refers to the contraction of a small muscle inside the eye to cause the natural lens in the eye to change its shape and allow images to focus properly on the back surface of the eye. As a result, a child who is farsighted usually does not have blurred vision. However in some children who are farsighted, this accommodative effort is associated with a reflex crossing of the eyes. Farsighted glasses control all of the eye crossing.
