[Binocular vision of concomitant esotropia after surgical correction].

Binocular vision of grade I or better was restored to 51.5% of 312 cases of concomitant esotropia after surgical correction. Cases of acquired, partially accommodative, and small-angle esotropia had better chances of restoration than did cases of congenital, non-accommodative, and large-angle esotropia (P less than 0.01), as were younger patients (less than 12 years) with satisfactory surgical correction than older patients with less satisfactory surgical correction. Factors that affected restoration of binocular single vision were discussed.
