title: [Vision deterioration after transsphenoidal surgery for removal of pituitary adenoma].
abstract: OBJECTIVE
  To explore the mechanism and strategies of prevention and treatment of vision deterioration after transsphenoidal surgery for removal of pituitary adenoma.
  
  
  METHODS
  From January 1980 to February 2001, 1 412 patients were operated on by transsphenoidal surgery to remove pituitary adenoma. Fourteen patients experienced vision deterioration after operation. Clinical data from the 14 patients with vision deterioration were analyzed retrospectively.
  
  
  RESULTS
  In this group, the incidence of vision deterioration was 0.99%. Over packing of the adenoma bed was seen in 5 patients, apoplexy of residual tumor in 3, high intracranial pressure in 2, vascular spasm in 2, injury of the optic nerve in the cannel in 1 and unknown reason in 1.
  
  
  CONCLUSIONS
  Vision deterioration is a severe complication after transsphenoidal surgery. Early diagnosis and treatment can greatly improve the vision.
