Managing solitary choroidal tuberculoma in an immunocompetent patient

Aim: We describe a case of young immunocompetent 18-year-old female patient who presented with sudden painless diminution of vision in left eye with vision of 20/100 on Snellen’s chart. Retinal evaluation showed a massive solitary choroidal granuloma. A positive Mantoux test (20X20 mm) was noted. The patient was started on anti-tubercular therapy and oral steroids and showed resolution of the granuloma with subretinal fluid at macula. After 3 months of oral therapy, the persistent subretinal fluid was managed with intravitreal injection of triamcinolone acetonide(2 mg). This case highlights favorable resolution of granuloma with oral therapy and a safer efficacy of triamcinolone acetonide in treating subretinal fluid due to choroidal tuberculoma with good visual outcome. Introduction: Choroidal tuberculoma is a rare ocular form of tuberculosis (TB) and is a diagnostic and a therapeutic challenge, especially when occurring without other manifestations of the disease.1,2 Involvement of the choroid occurs by direct infection or indirect immune‐mediated hypersensitivity and is the commonest clinical manifestation of intraocular TB.3 The presentation varies from a solitary choroidal granuloma (tuberculoma) to multiple choroidal tubercles, a subretinal abscess or choroiditis. We present a case of an immunocompetent patient, who presents with massive choroidal granuloma and responded to oral antitubercular and steroid therapeutic regimen. Visual acuity improved with intravitreal triamcinolone acetonide injection which resulted in resolution of subretinal fluid after 3 months
