Strabismus (cross-eyed) is when the eyes cannot align simultaneously on their own.
Facts:
- 5% of all children have some form of strabismum
- There is a 50% success rate as a result of surgical treatment only for strabismus
Causes:
- Genetics
- Inappropriate development of the "fusion center" of the brain
- Problems with the controlled center of the brain
- Injuries to muscles or nerves
Symptoms:
- Double Vision
- One eye will "turn off"
- Poor depth perception
- Anomalous Retinal Correspondence: non-corresponding retinal points are linked in the visual cortex to provide binocular fusion
Types:
- Constant Strabismus is when one eye is more near or far sighted than the other, making it challenging for the eyes to focus collectively.
- Intermittent Strabismic is when the brain is unable to align the eyes properly causing one eye to wander.
Diagnosis:
- Eye Examination
- Comprehensive Vision Evaluations
Treatment:
Treatment involves strategies to strengthen the weakened muscles and realign the eyes. Glasses and eye muscle exercises may be prescribed. Sometimes the doctor may prescribe an eye patch or recommend surgery to shorten the ligaments and tighten the muscles.
