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.
