Optical coherence tomography in choroidal tuberculosis

Am J Ophthalmol. 2006 Jul;142(1):170-2. doi: 10.1016/j.ajo.2006.01.071.

Abstract

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.
