title: Rectus eye muscle paths after surgical correction of convergent strabismus fixus.
abstract: OBJECTIVE
  To present a new surgical procedure for convergent strabismus fixus.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  A 69-year-old woman was referred to us because of esotropia of both eyes. Both eyes were fixed in a position of extreme adduction, and ocular motility was severely restricted in all directions. Magnetic resonance imaging demonstrated that the superior rectus (SR) was deviated nasally and the lateral rectus (LR) was deviated inferiorly. We performed operations for both eyes consisting of hemitranspositions of the SR and LR combined with a large recession of the medial rectus.
  
  
  RESULTS
  Postoperatively, the patient became able to fixate in primary gaze and ocular motility markedly improved in all directions. Magnetic resonance imaging confirmed that the paths of the SR and LR were corrected.
  
  
  CONCLUSIONS
  This surgical procedure appears to be a useful option for treating convergent strabismus fixus.
