title: [Healing process and complications after eye muscle surgery].
abstract: BACKGROUND
  Varying reports on the incidence of operative and postoperative complications following eye muscle surgery have been published. The purpose of this study was to quantify complications after various types of eye muscle surgery as well as minor pathological changes of the anterior and posterior segment.
  
  
  METHODS
  This prospective study included all patients who underwent eye muscle surgery at the Department of Strabismology and Neuroophthalmology, Giessen, from January to May 1998. Five hundred eyes of 377 patients aged 2-82 years were included. The spectrum of procedures comprised: recessions, resections, tucks, R&R procedures, transpositions, bimedial retroequatorial myopexies, and revisions of rectus and oblique muscles. All patients were examined 1 day preoperatively and 1 day, 1 week, and 3 months postoperatively. Any complications and even minor pathological changes of the anterior and posterior segment were documented. Some changes were assessed by means of a score (0-3).
  
  
  RESULTS
  One day postoperatively, 30% of eyes had inflammatory pseudoptosis, most of them mild. Conjunctival swelling and injection were frequently mild and moderate, after 1 week mostly mild. Conjunctival irritation was more pronounced following resection than tucking. Punctate epithelial keratopathy was noted in 1.6% of cases (first postoperative day), dellen in 4.3% (first postoperative week). Three months postoperatively, 14.3% of eyes had biomicroscopically visible conjunctival folds and 91.3% had minimal conjunctival scars. None of the patients had a scleral perforation or other serious complication.
  
  
  CONCLUSIONS
  Eye muscle surgery rarely entails complications. Revisions due to organic pathological changes are extremely rare. Possible development of dellen requires check-up 4-7 days postoperatively. Tucking of rectus muscles causes less conjunctival irritation than resection.
