Primary tubular choriorentinitis

The aim of this report is to emphasize that corticosteroids should not be prescribed when the etiological factors remain unidentified. A 34‑year‑old male visited our ophthalmology clinic suffering from blurred vision. Behçet’s disease had been diagnosed 5 years prior, and the patient was taking an oral immunosuppressant and a systemic corticosteroid. Vitreous cell count and foci of chorioretinitis (apparently confined to the ocular fundus) were evident. A vitreous sample was subjected to polymerase chain reaction, which resulted in the identification of and Mycobacterium tuberculosis. Treatment with a combination of four anti‑tuberculosis drugs was commenced. During the follow‑up, the vitritis disappeared, and the foci of active chorioretinitis improved. Systemic and Sub‑Tenon corticosteroid treatment should not be prescribed until vitreous and anterior chamber fluid samples have been evaluated in patients with uveitis. Some microbes are not detected on routine examination.Keywords: Corticosteroid therapy, Tuberculosis, Chorioretinitis, Uveitis
