The clinical efficacy was investigated of topical homologous fibronectin on persistent corneal epithelial defects of various etiologies. Fibronectin was purified from blood bank homologous plasma by gelatin-Sepharose 4B affinity chromatography. Twenty eight eyes of twenty five patients with persistent corneal epithelial defects and sterile corneal ulcers that failed to improve with standard therapy were treated by the instillation of homologous fibronectin eyedrops 5 times a day (500 microgram/ml). Complete reepithelialization was achieved in all patients except two eyes due to uncontrolled glaucoma and the taking of steroids. The healing time tended to be different depending on the duration of persistent corneal epithelial defects and the severity of underlying diseases. The mean +/- standard deviation duration of epithelial defect was 68.18 +/- 77.80 days. Average healing time was 42.07 +/- 17.47 days. Ocular symptoms were relieved significantly and no side effects were observed. Over an average follow-up period of about 8 months, two cases of recurrences were noted. These results show that homologous fibronectin was also effective in patients with persistent corneal epithelial defects and corneal ulcers.
