Which area is least likely to be affected by a herpes simplex keratitis lesion?

Herpes simplex keratitis-related changes tend to follow the sensory map of the trigeminal nerve, especially the ophthalmic division (V1). The forehead and the upper eyelids are in the V1 territory, so these areas are commonly affected when HSV reactivation involves the ocular region. The lateral lower eyelid is supplied by the infraorbital nerve from the maxillary division (V2), a different pathway less typically involved in ocular herpes. Because HSV keratitis favors V1 distribution, the lateral lower eyelid is the area least likely to be affected.
