Herpes zoster ophthalmicus complicated by ipsilateral isolated Bell's palsy: a case report and review of the literature

Neuro-ophthalmic complications of varicella-zoster virus

PURPOSE OF REVIEW

This review broadly describes recent neuro-ophthalmic manifestations of varicella-zoster virus (VZV) reported in literature.

RECENT FINDINGS

Despite varicella vaccination, the incidence of herpes zoster continues to rise, potentially leading to devastating consequences when ocular complications occur.A small but growing literature documents cases of retinal disease because of varicella reactivation after SARS-CoV-2 vaccination, ischemic optic neuropathy occurring during herpes zoster ophthalmicus, VZV-induced orbital apex syndrome, and immune-mediated ocular complications in patients with prior neuro-ophthalmic manifestations of VZV.

SUMMARY

It is important for clinicians to keep abreast of the diverse neuro-ophthalmic manifestations of VZV as early diagnosis and treatment often lead to better visual outcomes.

A practical approach to ocular pain for the non-ophthalmologist

Pain involving the eye has numerous etiologies and is a feared challenge of many clinicians. Between a fear of the patient losing vision and a lack of familiarity with the ophthalmic equipment necessary to diagnose the problem, working up eye pain can be a daunting task. While the ophthalmologist can be indispensable in challenging cases of eye pain, this article will help clarify the unique clinical features of each etiology that can help clinicians narrow down the differential and arrive at a diagnosis.
