Herpes zoster ophthalmicus

Herpes zoster ophthalmicus (HZO) occurs when latent varicella zoster virus reactivates in the ophthalmic division of the fifth cranial nerve (CNV1). HZO commonly affects elderly and immunocompromised patients. This disease is considered an ophthalmic emergency due to a wide range of associated ocular symptoms, including severe chronic pain and vision loss. HZO is typically a clinical diagnosis due to its classic presentation of a unilateral vesicular rash in the dermatomes corresponding to CNV1.
