The authors present three cases of severely restricted motility and large angle strabismus acquired rapidly during the first months of life in otherwise normal children who had normal eye alignment and movements at birth. Surgical treatment of these cases is difficult and outcomes are variable. Myositis causing extraocular muscles fibrosis is a possible cause of the strabismus in these cases.
