Optical coherence tomography in choroidal tuberculosis.
OBJECTIVE
To report the optical coherence tomographic (OCT) features in eyes with tuberculous choroidal granuloma.


METHODS
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.
