Abstract: Aspects of the present invention include methods for inhibiting damage to a mammalian cornea, comprising administering an effective ?-toxin inhibiting about of a composition that comprises a ?-cyclodextrin and cholesterol.

Abstract: Topical application of cholesterol has been found to be effective in preventing, treating or ameliorating the damage to the cornea caused by Streptococcus pneumoniae. Topical administration of cholesterol caused a significant decrease in the inflammation of the eye. In addition, cholesterol was surprisingly found to be a bactericide to Streptococcus pneumoniae outside the cornea. The effect of cholesterol can be enhanced by further administering a steroid or an antibiotic to the cornea.

Abstract: A method has been discovered for using lysostaphin as an effective antibiotic for topical treatment of Staphylococcus corneal infections (keratitis). Lysostaphin applied topically to the cornea by eye drops killed bacteria within the cornea; lysostaphin reduced the number of bacteria from approximately 10,000,000 viable bacteria colony forming units (“CFU”) in the untreated eye to essentially no viable bacteria in the treated eyes. Treatment by lysostaphin was more potent than any of the smaller antibiotics that have been previously tested (e.g., tetracyclines, erythromycins, cephalosporins, vancomycin, aminoglycosides, or fluoroquinolones). Moreover, topical application of lysostaphin was effective against the highly antibiotic-resistant Staphylococcus strains.
