- Description
- Ocular tuberculosis refers to necrotizing granulomatous uveitis caused by Mycobacterium tuberculosis infection. The mechanism of infection of ocular structures is via hematogenous dissemination of the bacteria during the primary infection. In this enucleation specimen, the anterior chamber and vitreous cavity are filled by caseous exudate. The iris is also replaced by a whitish material, and the retina is completely detached. Note the whitish thickening of the posterior choroid (arrow).
