title: Fixed dilated pupil (Urrets-Zavalia syndrome) in corneal dystrophies.
abstract: OBJECTIVE
  To report fixed dilated pupil following penetrating keratoplasty for corneal dystrophies.
  
  
  METHODS
  Retrospective chart analysis of subjects who underwent penetrating keratoplasty for corneal dystrophies between 1998 and 2002 at our institute.
  
  
  RESULTS
  Three of the subjects with fixed dilated pupils after penetrating keratoplasty had Macular corneal dystrophy and one subject had Fuchs Endothelial dystrophy. Fixed dilated pupils were noticed in the immediate postoperative period. None of the subjects had evidence for glaucoma either pre- or postoperatively. The follow up period ranged from 5 to 18 months.
  
  
  CONCLUSIONS
  Fixed dilated pupil (Urrets-Zavalia syndrome) can occur after penetrating keratoplasty for corneal dystrophies and may not be limited to eyes with keratoconus as previously reported.
