Crossed Eyes or Strabismus

Crossed Eyes are called Strabismus. Strabismus is a misalignment of the eyes that may cause vision to be disturbed and results from the extra ocular muscles of the eye not working in a coordinated manner.

One of the first things we address in treating Strabismus is the elimination of any coexisting Amblyopia which is often referred to as “Lazy Eye.” Some forms of Strabismus can be corrected by improving the vision in the Amblyopic eye inasmuch as the eye muscle control may improve at the same time. In addition, the eyes may straighten in some patients with Strabismus who require glasses to correct vision or Amblyopia.

An eye condition in which the direction that the eyes are pointing is not consistent with each other is called heterophoria. Patients with well-controlled heterophorias may need no treatment at all. Some forms of Strabismus, such as nerve palsies, are temporary and will resolve with time. Other forms, such as convergence problems that cause reading difficulties, will respond to exercises. Sometimes patients who have double vision may experience relief of the double vision and regain fusion and single vision through the use of prisms. Both permanent and temporary types of prisms are available to help patients.

If none of these treatments is indicated or is successful in straightening the eyes, then two options are available. One is eye muscle surgery, which involves the strengthening of weak eye muscle and weakening of overactive or tight muscle. The other option is the injection of Botulinum toxin into the eye muscle, which paralyzes them and straightens the eyes with certain forms of strabismus.
