Strabismus Surgery

Strabismus (eye misalignment) is Commonly known as cross-eyed or wall-eyed due to extraocular muscle imbalance either increasing or decreasing the tension of the small muscle on the surface of the eye. These muscles move the eye in all directions. Strabismus occurs in approximately 2% of children under 3 years of age and about 3% of children and young adults.

The condition affects males and females equally. Strabismus has an inherited pattern, it is much more likely to occur if one or both parents are affected. However, many cases occur without any family history of the disorder.

Treatment of strabismus may include patching of one eye (if amblyopia is present), glasses, or strabismus surgery to realign the eyes. It is important to understand that strabismus surgery does not help amblyopia (poor vision), and that this can only be corrected with patching and/or glasses. In some cases, realignment of the eyes occurs with proper prescription eyeglasses.

However, the majority of children with strabismus will eventually require strabismus surgery to better align the eyes.

Surgery for strabismus in adults aims at restoring alignment, eliminating diplopia, double vision, enabling sensory fusion making the two images you see become a single image. Surgery for strabismus in adults is carried out with minimal risks and a high rate of success.

Potential risks:

  • diplopia (double vision)
  • overcorrection or undercorrection which may require a reoperation

Benefits include:

  • Elimination of diplopia if it had occurred preoperatively
  • restoration or acquisition of sensory fusion
  • expansion of binocular visual fields
  • restoration of alignment; and improved psychosocial functioning

This list of benefits provides evidence that surgery for adult strabismus reaches beyond the cosmetic goal (restored alignment).
