[Zona ophthalmica and dendritic keratitis]. / Zona ophtalmique et kératite dendritique

Two cases of herpes zoster ophthalmicus with dendritic keratitis are reported. Virological studies confirmed the double infection with herpes simplex type 1 virus in the corneal lesions and herpes zoster virus in the cutaneous lesions. We suggest the use of the immunoperoxidase test to identify the viral agent mainly because of its rapid and specific results. We are against the use of local steroids in dendritic keratitis unless the etiological agent is proved to be herpes zoster virus and not herpes simplex virus.
