ABSTRACTPurposeIn the present study, antifungal activity of ozonated olive oil (OZO) and ozonated distilled water (ODW) in the treatment of experimentally induced keratitis with C. albicansin rabbits were investigated.MethodsThe Groups were composed of as 1, 2, 3, 4, 5, 7 (n = 5 rabbits, 10 eyes/in each group) and Group 6 (n = 10 rabbits, 20 eyes/in the group). Fourty-eight hours after C. albicansinoculation; Group 1 received fluconazle (FLU)+OZO drops, Group 2 received FLU drop, Group 3 received OZO drop, Group 4 received FLU+ODW drops, Group 5 received ODW drop, Group 6 (infected control group) and Group 7 received PBS drop (negative control group). Treatment continued in all groups for 22 days for every 8 hours.ResultsCornea cultures made 24 days post inoculation revealed statistically significant differences (p< 0,05) with concern to C. albicansamounts between Group 6 and Group 1–5. Statistical comparison of corneal opacity and corneal ulcer and conjunctivitis values among the Group 6 and Group 1–5 were also different significantly (p< 0,05) on days 20 and 24 post inoculation.ConclusionOZO and ODW were found to be effective in treating C. albicanskeratitis in the present study. It has also been proven by this study that ODW contain 26 μg/ml was the most effective in the treatment of C. albicanskeratitis.
