Tuberculin Skin Testing Induces Bilateral Tuberculous Uveitis in a Junior High School Student.

We report a rare case of bilateral tuberculous uveitis associated with tuberculin skin testing (TST) in an otherwise healthy junior high school student. A 12-year-old boy presented with severely decreased vision in both eyes and a history of an intradermal PPD (purified protein derivative) skin test 12 days earlier. The best-corrected visual acuity (BCVA) was 20/1000 in both eyes (OU). Ocular examination showed multifocal grayish-yellow choroidal tubercles. Laboratory examinations, including T-SPOT.TB, revealed no abnormal findings. He was diagnosed with tuberculous uveitis. Combined corticosteriod and anti-tuberculosis therapy (ATT) was given. The BCVA improved to 20/25, and the choroidal tubercles faded away. Our case suggests that TST may induce bilateral uveitis in rare cases.
