fadenoperation on the recti interni combined with anterior unstretching to treat some situations of strabismus convergence

ABSTRACT

The treatment of pateints who are orthotropic after wearing full cycloplegic correction or who have a minimal angle of esotropia at distance and a marked non-accommodative esotropia at near fixation is considered to be difficult. In 30 patients with an esotropia at far less than +10 degrees, but with a non accommodative esotropia ranging from +10 degrees to +25 degrees we performed a modified bimedial fadenoperation with an unstretching technique during attaching the muscle to the sclera. Postsurgically 26 patients reached alignment with binocularity. In these patients the mean deviation at far was +1 degrees and at close to +2.5 degrees. Two patients had a consecutive exotropia. In two patients the operation was uneffective with remaining convergence excess. The modified fadenoperation with unstretching of the anterior segment of the attached muscle is a suitable tool for the treatment of non - accommodative convergence excess with no or small esotropia
