title: Postoperative blindness following orbital surgery.
abstract: OBJECTIVE
  To determine the occurrence of blindness following orbital surgery.
  
  
  METHODS
  A retrospective study on 1593 cases who had undergone an orbital surgical procedure. Preoperative clinical examinations and radiological features were collected and reviewed, as well as the data regarding the postoperative outcome.
  
  
  RESULTS
  There were 7 cases of postoperative blindness (0.44%).
  
  
  CONCLUSIONS
  This percentage of cases with an unexpected development of blindness after surgery may represent a reasonable estimate of the general risk of encountering this complication after an orbitotomy. Many books and papers on orbital surgery make the reader aware that vision can be threatened after surgery due to the high risk of damaging the optic nerve, either directly or as a result of iatrogenic vascular damage caused by the surgical maneuvers. However, the percentage of postoperative blindness has not yet been widely reported.
