Introduction
Syphilis, caused by Treponema pallidum , is a sexually transmitted
infection known for centuries. Ocular involvement is considered to be a
form of neurosyphilis in terms of treatment. The disease may affect
every structure of the eye and it can mimic different ocular diseases,
which leads to diagnostic problems and delay in proper treatment. We
present a case report of a 46-year-old immunocompetent male, in whom the
first clinical symptom was binocular visual deterioration.
