Eye muscle surgery (strabismus)
Strabismus is a vision problem in which both eyes do not focus at the same object at the same time. Strabismus most often begins in early childhood. It is sometimes called crossed-eyes, walleye, or squint.
Normally, the muscles attached to each eye work together to move both eyes in the same direction at the same time. Strabismus occurs when the eye muscles don't work accurately to control eye movement. When the eye muscles don't work as they should, the eyes may become misaligned and the brain may not be able to merge what one eye sees with what the other eye sees.
The most common treatments for strabismus are:
Glasses. Wearing glasses sometimes correct mild strabismus.
A temporary eye patch over the stronger eye. This can make the weak eye stronger, which may help in aligning the eyes. Your child may have to wear the patch some or all of the time for a few weeks or months.
Surgery on the eye muscles. This is the only way to improve vision and for betterment in alignment of the eyes. It may take more than one surgery, and your child may still need to wear glasses.
