Ocular presentation of primary syphilis in a man with HIV.

The incidence of syphilis is rising, particularly among men who have sex with men. Ocular involvement, often manifesting as bilateral uveitis, typically occurs in later stages and is more severe and difficult to recognise in individuals living with HIV. We describe the case of a man with HIV infection who presented to our outpatient clinic with vision loss and a cutaneous maculopapular rash.
