• Thirty-four patients (49 eyes) who had dissociated vertical deviation were treated with the faden operation of Cüppers. The median follow-up period was 14 months. The operation produced good results in 23 of the patients, some improvement in seven, and did not help four. The posterior fixation suture was placed 14 mm behind the superior rectus muscle insertion and the superior rectus muscle was recessed.
