Herpes: Nerves
built 627 days ago
Herpes zoster usually clears in 2 to 3 weeks and rarely recurs. Involvement of motor nerves (nerves that control movement) may cause temporary or permanent nerve palsy (weakness or paralysis). Neuralgia (continued nerve pain) may persist for years in 50% of those over 60 years old who have shingles, particularly if the trigeminal nerve was affected. Eye lesions may lead to permanent blindness and require emergency medical care.

Herpes zoster ophthalmicus involves the tissues innervated by the ophthalmic division of the trigeminal nerve and accounts for 10-25% of all cases of shingles. The sequelae of herpes zoster ophthalmicus can be devastating and include chronic ocular inflammation, visual loss, and debilitating pain.

No, there is no current known cure for the herpes virus because the virus has evolved a highly effective survival tactic. The herpes virus hides dormant and undetectable within normal nerve cells and may stay dormant for many years. The dormant cells can become active because of stress, fever sunlight and possibly other unknown reasons. In fact there is no known cure for any virus including the common cold.

Ocular herpes is when the herpes virus has infected the eye. Genital herpes and oral herpes are both much more common than ocular herpes. Ocular herpes seems to most often develop when a dormant herpes virus makes home in the facial nerves.
