[Surgical correction of esotropias with unstable angles (author's transl)].

The authors report on the surgical procedure for retroequatorial myopexis, with and without rearward relocation. Analysis of the surgical procedure for retroequatorial myopexis of the rectus lateralis and medialis with and without rearward relocation: 1) simple myopexis - anchoring the muscle on the sclera 14 mm from the insertion of the rectus medialis (19 mm in the case of the rectus lateralis); 2) combined procedure (myopexis and rearward relocation). Forty patients with esotropia and unstable angle, as well as clear signs of a blockage, underwent surgery. In 47% of the patients sensoric orthophoria was achieved, in 43% a significant reduction of the angle; in 5% treatment resulted in overcorrection and in 5% the angle was unchanged.
