PURPOSE: To determine the effect of topical therapy with several corticosteroids with limited potency on viral clearance in the adenovirus type 5 (Ad5) rabbit ocular model.
METHODS: Sixty rabbits were inoculated in both eyes with Ad5. On the first day, the rabbits were equally divided into four topical treatment groups: 0.12% prednisolone acetate (PA), 0.1% fluorometholone (FM), 1% rimexolone (RMX), and control. Treatment was administered four times daily, in both eyes, for 3 days. All eyes were cultured for virus on days 0, 1, 3, 4, 5, 7, 9, 11, 14, 16, 18, and 21.
RESULTS: Compared with the control group, treatment with PA, FM, and RMX significantly increased the number of Ad5 positive eye cultures from days 7-21. Fluorometholone and RMX prolonged the duration of Ad5 shedding, and FM increased the mean combined Ad5 titer from days 1-5 and 7-21.
CONCLUSIONS: Treatment of an experimental ocular adenovirus infection with PA, FM, and RMX for 3 days significantly enhanced adenovirus replication compared with the control group. Short-term treatment of EKC with several commercially available topical corticosteroids with limited potency may offer symptomatic relief, but may also delay viral clearance and promote office and community epidemics.
