At what age does strabismus usually begin?
Studies of newborn babies have found that strabismus is not usually present at birth but develops within the first month of life, as vision develops. Some babies, however, squint from birth because the muscles that turn the eyes outward are not working properly. In such a case, even if the child’s head is held so that it cannot turn, the eyes will not move out beyond the central position in the attempt to see an attractive object such as a toy.
