INFANTILE ESOTROPIA

INFANTILE ESOTROPIA IS ANY ESOTROPIA which is known to be present before the age of one year. This knowledge may be from a history obtained from the parents or may be from examination by an ophthalmologist prior to the age of one year. The objectives of the present study are (1) to determine the characteristics which are representative of infantile esotropia, (2) to determine the percentage of cures (if any) after treating these patients, and (3) to list and qualify the factors which are important in obtaining a cure. In considering the first objective, we must recall that it has been stated' that infantile esotropia comprises a homogenous group characterized by a large deviation (50+ prism diopters), equal visual acuity, small to moderate hyperopia, and limitation of abduction O.U. However, two subsequently unpublished studies have stated that infantile esotropias run the gamut of motor and sensory findings. It seems important to obtain a more definitive answer to this question. Berke2 has stated that no congenital esotrope can obtain stereopsis, and thus a cure is not possible. This raises three questions. How should cure be defined? Is cure possible in congenital (and infantile) esotropia? Which of the -following factors favorably or unfavorably influence cure, if cure is possible? Some of these factors are:-
