Optical coherence tomography in choroidal tuberculosis.
PURPOSE: To report the optical coherence tomographic (OCT) features in eyes with tuberculous choroidal granuloma. DESIGN: Interventional case series. METHODS: Nine eyes of nine patients with tuberculous granuloma of the choroid were studied using OCT scans. RESULTS: OCT scan through the lesions revealed a distinctive feature of attachment between the retinal pigment epithelial- choriocapillaris layer and the neurosensory retina over the granuloma ("contact" sign). This was associated with surrounding subretinal fluid and inflammatory infiltrate in the deeper retinal layers. CONCLUSIONS: OCT can be useful in the differentiating choroidal tuberculous granulomas from noninflammatory lesions with a similar clinical appearance.
