Choroidal tuberculomas without evidence of extraocular tuberculosis
1Department of Ophthalmology, University of Texas Medical Branch, Galveston 77550.
Summary
Tuberculosis can manifest as disseminated choroiditis, causing unilateral visual loss. Prompt antituberculous therapy can restore vision, highlighting choroiditis as key evidence of mycobacterial spread.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Tuberculosis (TB) is a significant global health concern.
- Ocular involvement in TB can be challenging to diagnose.
- Disseminated choroiditis is a rare but critical manifestation of TB.
Observation:
- A 32-year-old male presented with sudden, unilateral visual impairment.
- Ophthalmic examination revealed extensive choroidal nodules and granulomatous optic neuropathy in one eye.
- No overt signs of systemic or extraocular tuberculosis were clinically apparent.
Findings:
- The patient's visual loss and ocular findings demonstrated a significant response to antituberculous therapy.
- Choroidal nodules and optic neuropathy resolved with treatment, leading to visual recovery.
- This case underscores the potential for ocular findings to be the sole indicator of disseminated tuberculosis.
Implications:
- Disseminated choroiditis can serve as the initial presenting sign of tuberculosis.
- Ocular examination provides accessible, non-invasive evidence of mycobacterial dissemination.
- Early recognition and treatment of ocular TB are crucial for preventing vision loss and diagnosing systemic infection.
