Left syphilitic retinitis

Last edited: 4/15/2026

Overview

Syphilitic retinitis, a manifestation of neurosyphilis, involves inflammation and necrosis of retinal tissue, often leading to visual impairment and potential blindness if untreated 1.

Diagnosis

  • Clinical presentation: Visual disturbances, retinal lesions visible on fundoscopy 1.
  • Diagnostic tests: Fluorescent treponemal antibody absorption (FTA-ABS) test, Venereal Disease Research Laboratory (VDRL) test, and Treponema pallidum particle agglutination (TP-PA) test for serological confirmation 1.
  • Imaging: Colour stereociné photography through an operation microscope can provide detailed stereoscopic views of retinal lesions for accurate assessment 1.

    • Management

  • First-line treatment: Penicillin G, typically administered intravenously (e.g., aqueous crystalline penicillin G 18-24 million units daily for 10-14 days) 1.
  • Adjunctive treatments: No specific adjunctive therapies mentioned beyond penicillin treatment 1.

    • Special Populations

  • Pregnancy: Management should prioritize maternal and fetal safety; penicillin remains the drug of choice, with careful monitoring 1.
  • Pediatrics: Similar treatment principles apply, with dose adjustments based on weight; close follow-up is essential 1.
  • Elderly: No specific modifications noted; standard penicillin therapy is recommended with consideration for comorbidities 1.
  • Comorbidities: No specific guidelines provided; treatment should be individualized based on overall health status 1.

    • Key Recommendations

  • Confirm diagnosis using serological tests (FTA-ABS, VDRL, TP-PA) and advanced imaging techniques like stereociné photography 1 (Evidence: Strong).
  • Initiate treatment with intravenous penicillin G for at least 10-14 days 1 (Evidence: Strong).
  • Tailor management in special populations, particularly emphasizing safety and close monitoring in pregnant women and pediatric patients 1 (Evidence: Moderate).
