AbstractBackgroundPeople living with HIV are disproportionately represented among people with severe mpox. Mild and self‐limiting conjunctival involvement has been well‐documented, and severe ocular complications, including keratitis, corneal scarring, and the associated loss of vision, are increasingly recognized. Tecovirimat is the first‐line antiviral therapy for severe mpox, but data around the efficacy of systemic antiviral agents for mpox are limited, particularly in cases of ocular mpox.Case ReportHere, we describe a case of sight‐threatening necrotic blepharokeratoconjunctivitis in a person with advanced HIV, requiring an extended course of tecovirimat due to persistent mpox viral shedding for nearly 5 months.
