- Reactivation of virus spreads along the dermatomal distribution of infected nerves and can occur many years after the initial infection.
Herpres zoster reactivation
- It’s considered benign unless it affects an immunocompromised host or is a reinfection of the V1 branch of the trigeminal nerve with eye/cornea involvement.
The trigeminal nerve supplies feeling and movement to the face. It has three divisions that branch from the trigeminal ganglion: ophthalmic division (V1) provides sensation to the forehead and eye, maxillary division (V2) provides sensation to the cheek, and mandibular division (V3) provides sensation to the jaw
This is a case of HZO with evident cutaneous involvement of the V1 branch of the trigeminal nerve
