Bilateral choroidal tuberculoma in a patient of miliary tuberculosis.

Abstract

Background: Choroidal granuloma is one of the common manifestations of ocular tuberculosis. Tubercles indicate hematogenous dissemination of the disease. Tubercular granulomas respond to Anti-Tubercular Treatment (ATT) and systemic corticosteroids. However, in some patients with large granulomas involving macula, adjunct treatment with intravitreal anti-VEGF may be required for prompt management of the granuloma.

Findings: We report a case of bilateral Tubercular granuloma in a patient with miliary Tuberculosis (TB). The patient was an immunocompetent young female with miliary tuberculosis. Mantoux was positive. HRCT chest suggested miliary TB. The patient was already on ATT. Clinical examination showed multiple TB granulomas in both eyes, with a large granuloma involving the fovea in the left eye. She underwent intravitreal injection of the anti-VEGF drug bevacizumab (1.25 mg/0.05 mL) (off-label use) with moxifloxacin (500 µg/0.1 mL) (off-label use) in the left eye. She was continued on ATT and was started on oral steroids. After seven weekly intravitreal injections in the left eye at the second-month follow-up, lesions were consolidated and scarred. Optical coherence tomography showed a decrease in the size of the choroidal bump.

Conclusion: Weekly administration of intravitreal Anti-Vascular endothelial growth factor(VEGF) and moxifloxacin, along with ATT and oral corticosteroids, has controlled inflammation and has caused consolidation and scarring of TB granulomas in a patient with miliary TB.
