Monolateral visual loss due to cryptococcal meningitis.

A case of retrobulbar monolateral optic neuritis due to disseminated Cryptococcosis in a 32-year-old man with a new diagnosis of AIDS is described in the era of combination antiretroviral therapy (cART). The patient presented a monolateral rapid visual loss on day 7 of a liposomal amphotericin B treatment. Neuroradiological imaging showed the presence of retrobulbar neuritis. After starting ART and intravenous metilprednisolone 1 g daily for 3 days, we assisted to a progressive improvement of visual acuity. At 3 months of follow-up, complete clinical resolution was obtained. In this case, in the presence of effective antiretroviral and antifungal treatment, a short course of metilprednisolone was a safe therapy.
