Congenital esotropia with a bifixation result. Report of a case

Surgical alignment of the eyes in congenital esotropia within the first two years of age can result in the development of binocular vision. With one exception, reported here, the binocular vision has been extramacular and never macular. In this one case the patient was proven to be a bifixator. This is such an unusual outcome that the diagnosis of congenital esotropia must be questioned. Moreover, dissociated double hypertropia was not found in this case.
