Cutaneous eruption with or without ocular complications in patients with herpes zoster involving the trigeminal nerve.

We examined 62 patients with acute herpes zoster involving the trigeminal nerve; 13 had eruptions only and 49 (51 eyes) had eruptions with ocular complications. Bilateral involvement was found in two patients. The frequency of the disease appeared to increase with age, and the disease was least active in November. Patients with eruptions only demonstrated affected areas along the first, second, and/or third divisions of the trigeminal nerve. Ocular complications occurred in patients who had eruptions along the first and/or second divisions of the nerve, and they were usually noted in patients with eruptions on the tip and one side of the node. The ocular complications and associated systemic conditions varied.
