Factors contributing to corneal complications after vitrectomy in diabetic patients
1Department of Ophthalmology, Diabetes Center, Tokyo Women's Medical College, Tokyo, Japan.
Purpose:
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.
Conclusion:
Surgical invasion is a risk factor for corneal complications after vitrectomy in diabetic patients.
