Purpose: To evaluate the efficacy of systemic and topical antiviral therapy in the treatment of active herpes simplex virus (HSV) necrotizing stromal keratitis (NSK). Design: Prospective interventional case series. Methodology: Patients with a diagnosis of HSV NSK based on history and clinical findings were enrolled in the study. A standard protocol was used for microbiologic investigations. Ten weeks regime of systemic acyclovir and 2 weeks of topical acyclovir was given. Complete ophthalmic examination was performed at every visit. Outcome measures were a reduction in the area of infiltration and improvement in visual acuity. Results: Fifteen patients were enrolled in the study. The mean age of presentation was 51.53 years. The duration of symptoms at presentation ranged from 2 to 8 weeks. HSV1 DNA polymerase chain reaction was positive in 70% cases of those tested. Area of infiltration at trial entry and at the end of 2 weeks of antiviral treatment reduced significantly (P = 0.007). All patients showed a complete resolution of keratitis at the end of study. Conclusion: Topical and systemic acyclovir for treatment of NSK facilitates healing of ulceration. Topical steroids after initial antiviral therapy are safe and decreases inflammation and improve visual recovery. Early initiation of therapy has better outcomes as compared to late presentations.
