When does infantile esotropia present? What are its clinical features?
As the name implies, this condition occurs during infancy. It may present at birth but most cases present within the first six months of life. Characteristically, this type of deviation shows a large angle of deviation, so large that either eye may appear unable to move sideways and may even use the head to look at objects in the peripheral field of vision. The child usually shows a strong preference of fixation with one eye indicating the presence of amblyopia. This occurs in about half of cases. When amblyopia sets in, the child has poor prognosis for high-grade stereopsis.
