Background:
Syphilis is a multisystem bacterial infection caused by Treponema pallidum. The incidence of infection in the United States has risen by more than 75% since the year 2000, when it was at a low of 2.1 per 100,000 people. Ocular involvement may occur in any stage of infection and may present in a variety of ways, with posterior uveitis being the most common manifestation. We report a case of ocular syphilis infection with an unusual presentation of bilateral non-granulomatous panuveitis with papillitis and unilateral focal chorioretinitis.
Findings:
This is a retrospective case report with literature review. A 39-year-old Caucasian female presented with a 2-week history of bilateral ocular flashes and left eye pain. Dilated fundus examination revealed mild optic disc edema in both eyes, the right eye more than the left. In the left eye, there was an area of retinal elevation and whitening involving the peripheral retina. Fluorescein angiography, B-scan ultrasonography, and ocular coherence tomography were performed, and laboratory tests were ordered based on the clinical presentation. After rapid plasma reagin (RPR) and fluorescent treponemal antibody absorption (FTA-Abs) were positive, syphilitic uveitis was confirmed, and the patient was admitted for a 14-day course of high-dose intravenous penicillin G.
Conclusions:
The first signs and symptoms of syphilis may be ocular, which can lead to a diagnostic challenge. A high index of suspicion is the key for early diagnosis of ocular syphilis. Prompt treatment with intravenous penicillin G is highly effective in resolving the infection.
Insights
Ocular syphilis, a rising concern, can present unusually. Early diagnosis requires a high index of suspicion, and prompt intravenous penicillin G treatment effectively resolves this Treponema pallidum infection.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Syphilis, caused by Treponema pallidum, is a multisystem infection with a >75% incidence rise in the US since 2000.
- Ocular involvement is common in syphilis, often manifesting as posterior uveitis.
- This case highlights an unusual presentation of bilateral panuveitis with papillitis and unilateral chorioretinitis.
Purpose of the Study:
- To report a rare case of ocular syphilis with an atypical presentation.
- To emphasize the importance of early diagnosis and prompt treatment of ocular syphilis.
- To review the diagnostic challenges and management of syphilitic uveitis.
Main Methods:
- Retrospective case report with literature review.
- Clinical examination including dilated funduscopy, fluorescein angiography, B-scan ultrasonography, and ocular coherence tomography.
- Laboratory confirmation using rapid plasma reagin (RPR) and fluorescent treponemal antibody absorption (FTA-Abs) tests.
Main Results:
- A 39-year-old female presented with bilateral ocular flashes and unilateral eye pain.
- Fundus examination revealed bilateral optic disc edema and unilateral peripheral retinal elevation/whitening.
- Positive RPR and FTA-Abs confirmed syphilitic uveitis.
Conclusions:
- Ocular manifestations can be the initial sign of syphilis, posing diagnostic challenges.
- A high index of suspicion is crucial for the early diagnosis of ocular syphilis.
- Intravenous penicillin G is effective for treating ocular syphilis, leading to infection resolution.
