Syphilitic Uveitis With Diverse Clinical Presentations: Multimodal Imaging as a Useful Adjunctive Tool for Diagnosis and Treatment.

We report four cases of syphilitic uveitis with diverse clinical presentations. All patients were men who have sex with women, and were aged 19-68 years, and none were HIV-positive. All cases were bilateral. One case presented with anterior uveitis, while three exhibited panuveitis. One patient had acute syphilitic posterior placoid chorioretinitis and two had retinal vasculitis resulting in damage to the outer retinal and retinal pigment epithelium. The rapid plasma reagin (RPR) test and (TP) hemagglutination test were both positive in all cases. Six of eight eyes had improved vision and best-corrected visual acuity better than 20/20 after antibiotic treatment. Serological testing is mandatory for the diagnosis of syphilitic uveitis. Additionally, multimodal imaging, including optical coherence tomography (OCT), fundus autofluorescence (FAF), and fluorescein angiography (FA), can provide useful adjunctive information for early diagnosis and assessment of treatment response.
