As has been established in rabbits, (E)-5-(2-bromovinyl)-2'-deoxyuridine (BVDU) is superior to 5-iodo-2'-deoxyuridine (IDU) in the topical treatment of epithelial HSV-1 (herpes simplex virus type 1) keratitis, and superior to 5-trifluoromethyl-2'-deoxyuridine (TFT) in the topical treatment of deep stromal HSV-1 keratitis and HSV-1 uveitis. BVDU 0.1% eye drops have also proven efficacious in the treatment of patients with dendritic corneal ulcers, geographic corneal ulcers and stromal keratitis, and combined treatment of BVDU 0.1% eye drops with oral BVDU at 375 mg/day for 5 days led to a prompt healing of keratouveitis and skin lesions in patients with ophthalmic herpes zoster.
