What Is Strabismus?

Strabismus—misalignment of the eyes—is a common condition that can cause worrisome symptoms, including focusing difficulty and double vision. Eyestrain and headaches can also develop when the eyes are not working together.

While strabismus is very common in childhood, it also occurs in adults. Many of the problems that develop in adults are a consequence of previous childhood problems, but there can be new issues that can affect the alignment of the eyes during adulthood.

There are two types of strabismus:

  • Esotropia: An eye turns in, toward the other eye
  • Exotropia: An eye that turns out, away from the other eye
