Factors contributing to corneal complications after vitrectomy in diabeticpatients

Purpose: To elucidate factors contributing to corneal complications after v itrectomy in diabetic patients. Methods: The records of a series of 129 diabetic patients (202 eyes) who un derwent pars plana vitrectomy performed by a single surgeon between March 1 997 and February 1999 were analyzed retrospectively. Logistic regression an alysis was performed to determine possible factors contributing to corneal complications. Results: Of the 202 eves, 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 af ter vitrectomy in diabetic patients. Jpn J Ophthalmol 2001;45:492-495 (C) 2 001 Japanese Ophthalmological Society.
