Infectious Retinal and Choroidal Inflammation
Even though one-third of the world’s population has been exposed to Mycobacterium tuberculosis, active M tuberculosis uveitis is uncommon, even in endemic areas. Suggestive clinical findings include solitary (Fig 11-19) or multifocal choroiditis, serpiginous-like chorioretinitis, and Eales disease–like peripheral nonperfusion in association with uveitis. Patients suspected of having tuberculous uveitis should undergo testing for prior M tuberculosis exposure, including a chest X-ray and either purified protein derivative (PPD) skin testing or a blood-based interferon-gamma release assay.

Once the diagnosis of ocular tuberculosis is either confirmed or strongly suggested, the patient should be treated for extrapulmonary tuberculosis as recommended by either the US Centers for Disease Control and Prevention or the World Health Organization.
