Abstract:
We report a case of a 36-year old patient who suffered from a unilateral painless loss of vision. Ophthalmological examination in the context of a highly reactive syphilis serology revealed an acute syphilitic posterior placoide chorioretinitis (ASPPC). Additional clinical findings were a mucosal lesion on the upper lip, consistent with a plaque opaline and an alopecia specifica as manifestation of secondary syphilis. Treatment consisted in 6 x 4 Mio. IE* Penicillin G for 14 days and 50 mg Prednisone for five days to prevent a Jarisch Herxheimer reaction. The diagnostic measures, therapy and follow up of syphilis, focusing on ocular involvement, are described.
