A 50-year-old African American man with HIV infection had a CD4+ T-cell count of 18/μL (1%), CD8+ cell count of 1035/μL (69%), and CD4:CD8 ratio of 0.01 at the time of diagnosis. He had multiple erythematosquamous skin lesions over his forehead, face, chest, back, and extremities

Bilateral retrobulbar optic neuritis developed in a 38-year-old woman with advanced HIV infection. This was secondary to varicella-zoster virus (VZV) infection, confirmed by polymerase chain reaction detection of VZV in the patient's cerebrospinal fluid. There was no evidence of retinitis, and the ocular symptoms preceded the rash. This case illustrates that a new onset of unexplained visual loss resulting from optic neuritis in an HIV-positive patient may be caused by VZV infection. Clinicians should be aware of this unusual manifestation of VZV infection. Prompt recognition and early intervention with antivirals are needed, but it is unclear how much vision can be preserved.

It results from reactivation of latent varicella-zoster virus (VZV) within the
