Delayed corneal epitheliopathy after antimetabolite-augmented trabeculectomy.
OBJECTIVE
The authors describe the first case of delayed antimetabolite-related corneal epithelial toxicity after trabeculectomy and its successful treatment with limbal stem cell transplantation.


METHODS
A 73-year-old woman underwent trabeculectomy with intraoperative mitomycin C. After surgery she received six 5-mg injections of subconjunctival 5-fluorouracil (5-FU) adjacent to the bleb.


RESULTS
The patient had a functioning trabeculectomy and clear cornea until 30 months after surgery, at which time she developed a nonhealing superior corneal epithelial defect. After 4 months of conservative medical management, an autologous limbal stem cell transplantation was performed. The epithelial defect resolved completely within 1 week of limbal stem cell transplantation.


CONCLUSIONS
Delayed corneal epithelial toxicity may be a late complication of antimetabolite-augmented trabeculectomy.
