title: [Acquired progressive esotropia and acquired strabismus fixus].
abstract: OBJECTIVE
  We previously reported on acquired convergent strabismus fixus and its incomplete type of esodeviation, which we named acquired progressive esotropia. In this study, we tried to confirm that the esotropia was acquired and progressive and to determine the most appropriate surgical procedure.
  
  
  METHODS
  Forty-three cases, 32 of acquired progressive esotropia and 11 of acquired convergent strabismus fixus with severe myopia, were rechecked to evaluate their clinical and physiological features. Thirty-seven cases underwent strabismus surgery and the surgical results were also evaluated.
  
  
  RESULTS
  We obtained positive proof that the esodeviation was an acquired situation and progressed into convergent strabismus fixus from some pictures at a young age. The condition of some of these patients developed into convergent strabismus fixus in a short time. Combined recession-resection operation and transposition of superior and inferior rectus muscles were effective for the patients without severe abducting disorders.
  
  
  CONCLUSIONS
  We must make a certain diagnosis of progressive esotropia in the early stages, because the condition of some of these patients will develop into strabismus in a short time if we miss the appropriate time for surgery.
