A 29-year-old man presents for follow-up of a positive syphilis serologic test result. Recent laboratory studies from a routine visit 8 days ago show a positive treponemal enzyme immunoassay (EIA) and a positive Rapid Plasma Reagin (RPR) with a titer of 1:256. He had a negative HIV-1/2 antigen-antibody test and is taking tenofovir DF-emtricitabine for HIV preexposure prophylaxis (PrEP). He had testing for sexually transmitted infections, including syphilis, 3 months ago and these tests were all negative. He returns to receive treatment for syphilis. He denies any genital ulcers or skin manifestations, but he reports blurry vision in the right eye during the past 4 days. A diagnosis of ocular syphilis is suspected.
