Inhibition of pseudomonal ulceration in rabbit corneas by a synthetic matrix metalloproteinase inhibitor.

Abstract

Pseudomonal protease activity in culture broth consisted predominantly of metalloproteinases and were effectively inhibited by Galardin in vitro. Topical treatment with Galardin prevented destruction of rabbit corneas by bacterial products present in culture broth, and it delayed corneal destruction after injection of PA bacteria. Galardin may be a useful adjuvant when corneal destruction proceeds despite prompt antibiotic treatment.
