Purpose: To describe a case of long-term poorly treated bilateral acute syphilitic posterior placoid chorioretinitis (ASPPC) complicated with choroidal neovascularization, with a multimodal imaging approach.
Patients And Methods: Retrospective case report. Analysis of patient's clinical data.
Case Report: A healthy 66-year-old man complained of decreased visual acuity in the right eye (RE). He had a past history of bilateral exudative maculopathy of unknown etiology, lasting for more than 10 years and leading to severe and irreversible vision loss on the left eye. The corrected distance visual acuity (CDVA) was 20/63 on the RE and <20/400 on the left eye (LE). On slit-lamp, no anterior chamber reaction was observed, a vitreous haze was present on the RE as well as large, bilateral yellowish lesions in the macula, with exuberant macular atrophy, particularly on the LE. These well-defined lesions were confined to the posterior pole. The spectral domain optical coherence tomography (SD-OCT) showed a flat retinal pigmented epithelium (RPE) detachment with hyperreflective material beneath the RPE and cystoid macular edema on the RE and an exuberant macular atrophy on the LE, with both eyes showing anomalous enlargement of choroidal vessels. The fluorescein angiography showed general hypofluorescence and indocyanine green angiography revealed a heterogeneous pattern. The OCT angiography (OCTA) of the RE demonstrated an anomalous vascular network related to the presence of choroidal neovascularization (CNV). An etiological study was performed and a positive treponemal test (TPHA) was found. The patient experienced visual acuity improvement to 20/25 after systemic treatment with Penicillin and anti-VEGF injections.
Conclusion: Clinical data and multimodal imaging information suggest that this case represents a complication of long-term untreated bilateral acute syphilitic posterior placoid chorioretinitis (ASPPC) with associated choroidal neovascularization. Once the RE presented signs of active disease, besides intravitreal anti-VEGF, treatment of the underlying disease was essential for visual recovery.

Neuron-derived neurotrophic factor (NDNF) was discovered as a target antigen in membranous nephropathy (MN) caused by syphilis. However, there have been few reports of NDNF-positive MN in Japan. A 19-year-old female patient was admitted to our hospital with nephrotic syndrome and acute kidney injury.

- * Initial visual assessments revealed significant vision loss in the left eye and worsening conditions in the right eye, with diagnostic tests confirming syphilis as the underlying cause of the retinitis.
- * After receiving treatment with benzathine penicillin and doxycycline, the patient's vision improved markedly in both eyes, demonstrating the effectiveness of addressing syphilitic retinitis.
A Rare Case of Rash, Blurry Vision, and Papilledema Caused by Isolated Ocular Syphilis.

Papilledema is a high-risk cause of vision changes in the Emergency Department (ED) and a critical physical examination finding because of its close association with etiologies that may progress to vision loss or death. Syphilis is a rare infectious cause of papilledema, with scarce case reports published showing its ability to develop such sequela. We present a case of a 35-year-old male with a past medical history of newly diagnosed HIV who originally presented to the ED with a rash and rapidly worsening visional changes.

Purpose: Syphilis is a re-emerging infectious disease with various systemic manifestations, including ocular involvement, which can lead to significant morbidity if untreated. This study aims to analyze the ocular manifestations of syphilis in patients treated at a Portuguese tertiary center over a 14-year period.
Patients And Methods: A retrospective review of patients diagnosed with syphilis who presented with ocular symptoms from 2010 to 2023 was conducted.

Article Synopsis
- Penicillin is the primary treatment for syphilis, but some patients experience ongoing eye issues like visual loss due to chronic inflammation or incomplete treatment.
- In a case series of three patients, two experienced persistent syphilitic retinal conditions despite being treated with penicillin, leading to additional treatments or reinforcement of therapy.
- Recommendations emerging from these cases emphasize ensuring complete initial penicillin treatment and monitoring inflammatory responses to optimize recovery and visual outcomes.
