Prognostic value of Hutchinson's sign in acute herpes zoster ophthalmicus.

Purpose: To determine the prognostic value of nasociliary skin lesions (Hutchinson's sign) for ocular inflammation and corneal sensory denervation in acute herpes zoster ophthalmicus.

Methods: A longitudinal observational study with a 2-month follow-up was performed involving 83 non-immunocompromised adults with acute herpes zoster ophthalmicus, with a skin rash duration of less than 7 days, referred by their general practitioner. All skin lesions at the tip, the side and the root of the nose, representing the dermatomes of the external nasal and infratrochlear branches of the nasociliary nerve, were documented by taking photographs and marking anatomical drawings.
