Spectral domain optical coherence tomography imaging of tubercular chorioretinitis and intraretinal granuloma. Intraretinal tuberculosis: a case report

摘要

The aim of this study is to report the clinical and spectral domain optical coherence tomography (SD-OCT) findings in a patient suffering from ulcerative colitis with bilateral tubercular chorioretinitis and intraretinal granuloma regressed with systemic antitubercular therapy (ATT). This study is a case report of a 33-year-old Bangladeshi male with ulcerative colitis treated with oral corticosteroids and azathioprine who was referred to our department with a diagnosis of central serous chorioretinopathy. Serological tests, the Mantoux skin test, complete ophthalmologic examination, ocular fundus photography, fundus fluorescein angiography, and SD-OCT scans were performed. The ophthalmological inflammatory pattern and serological investigations provided an early diagnosis of ocular tuberculosis. Systemic ATT led to significant improvement and resolution of the ocular inflammation. SD-OCT was a useful non-contact imaging technique in the follow-up of tubercular choroiditis. The excellent response to systemic ATT confirmed the clinical diagnosis. This is an unusual case of tubercular chorioretinitis with intraretinal granuloma and is the first such SD-OCT description reported in the ophthalmological literature.
