title: Factors contributing to corneal complications after vitrectomy in diabetic patients.
abstract: OBJECTIVE
  To elucidate factors contributing to corneal complications after vitrectomy in diabetic patients.
  
  
  METHODS
  The records of a series of 129 diabetic patients (202 eyes) who underwent pars plana vitrectomy performed by a single surgeon between March 1997 and February 1999 were analyzed retrospectively. Logistic regression analysis was performed to determine possible factors contributing to corneal complications.
  
  
  RESULTS
  Of the 202 eyes, 102 (50.5%) developed corneal complications after surgery; 90 (44.6%) had epithelial disturbance; and 48 (23.8%) had corneal edema. The degree of surgical invasion during vitrectomy was significantly correlated with the occurrence of epithelial disturbance and corneal edema.
  
  
  CONCLUSIONS
  Surgical invasion is a risk factor for corneal complications after vitrectomy in diabetic patients.
