An Old Disease With an Unfamiliar Face: A Case Report of Ocular Syphilis.

Syphilis is an infection caused by the bacterium Treponema pallidum. Patients with syphilis can present with a wide range of symptoms depending on the stage of disease. An underappreciated manifestation of syphilis is ocular involvement, which has been increasingly reported in the last several years. Delay in diagnosis and treatment of ocular syphilis can increase the risk of irreversible vision loss. Syphilis can affect almost every structure in the eye; however, most commonly presents with panuveitis. Ocular syphilis is treated similarly to neurosyphilis with prompt initiation of intravenous penicillin G.
