[Surgery for convergent strabismus in childhood: why and when?].

The authors explain the reasons for and the timing of surgery for convergent strabismus, or esotropia, in children as a function of the particular type of strabismus. The goal of surgery is to correct the cross-eyed deviation by choosing the most opportune time so as to obtain the best binocular result with the minimum number of surgeries. The authors take a position in the debate over age at time of surgery for childhood esotropia, which is still controversial. Their arguments are based on recent neurophysiological and clinical data.
