Herpes Zoster is known to target which nerve associated with Hutchinson's sign?

Hutchinson's sign is associated with the involvement of the nasociliary nerve, which is a branch of the ophthalmic division of the trigeminal nerve. When herpes zoster (shingles) affects this nerve, it often manifests as a rash on the forehead and the upper eyelid, which can lead to complications like keratitis or conjunctivitis. The presence of Hutchinson's sign — vesicular lesions on the tip of the nose — indicates that the herpes zoster infection is affecting the nasociliary nerve and poses a higher risk of ocular involvement.

Other nerves listed, like the maxillary, optic, and mandibular nerves, are either not directly related to Hutchinson's sign or do not lead to the same clinical implications concerning the eye. Therefore, understanding the relationship between herpes zoster, nasociliary nerve involvement, and Hutchinson's sign is crucial in anticipating and managing potential complications.
