Herpes zoster arteritis. Clinical and angiographic features.

: Herpes zoster ophthalmicus is a common condition, and has now been widely recognised as associated with the delayed onset of neurological events, associated with angiographic evidence of arteritis. The time lag between the zoster and subsequent neurological symptoms, along with the age of the patients, often leads to a missed diagnosis. As more cases are recognised, the pathogenic mechanisms will be better characterised and treatment may become more effective.
