Esotropia and binocular vision in young age group

ABSTRACT

Bimedial rectus resecion more than the traditional 5.mm [6 mm] proved to be an effective surgical procedure for cases of congenital esotropia. It gives good post- operative alignment especially when the angle of deviation was less than 45 D. The success rate in our series was 60%. The remaining 40% developed post-operative residual angle which ranged from 10- 12 D [pre- operative angle of deviation was more than 50 D]. It can be considered as a success because the residual angle was corrected by hyperopic glasses. Early interference for cases of congenital esotropia helps to improve binocular vision and minimizes the development of amblyopia, the older the child the less will be the improvement in binocular vision. Cases of accommodative esotropia with large AC/A ratio and poor response to hyperopic correction for 6 months are better to be operated upon early by 2 or 3 muscle surgeries according to the pre- operative angle of deviation
