Varicella Zoster, the recrudescence of the dormant
varicella virus, occurs more often in older patients and
in those who are immunocompromised. Herpes Zoster
ophthalmicus (HZO) is the second most common
manifestation of the disease, second only to thoracic and
lumbar zoster.1 HZO is estimated to account for 10% to
25% of cases.2,3 HZO can lead to a number of ocular
complications, including proptosis, disciform keratitis,
internal ophthalmoplegia, bilateral retinal detachments,
Argyll-Robertson pupil, and progressive outer retinal
neuropathy (PORN).
