Abstract
Patients (35) with herpes simplex keratitis were treated in a double-blind clinical trial. Patients (18) (10 with pure epithelial and 8 with accompanying stromal affection) were treated with 3% acyclovir (ACV) eye ointment, and 20 patients (10 with pure epithelial and 10 with accompanying stromal affection) were treated with 0.5% of idoxuridine (IDU). The cure rate was 94% in the ACV group compared to 70% in the IDU group. This was significantly higher in the ACV group. Only minor adverse reactions were recorded.
