4. Recurrent anterior Uveitis (≥ 2 episodes of ocular inflammation within the past 2 years before inclusion with a free-interval of at least 3 months between ocular inflammations, patients with a second episode of ocular inflammation may be included in the study) or chronic anterior Uveitis (persistence of ocular inflammation = partial response after 3 months of well-conducted local treatment) .
5. Positive Quantiferon test (QFN) performed after the first episode of ocular inflammation (accepted tests: Quantiferon-TB-Gold, Quantiferon-TB-Gold in tube or Quantiferon plus) with a threshold ≥ 1 IU / ml or associated with a positive ELISPOT test if the QFN level is between 0.7 and 1UI / l.

6. Absence of other etiology that may explain anterior uveitis during etiological investigations

   1. Serology of herpes group viruses (HSV,, CMV, VZV) negative or old immunity (achieved after the first episode of ocular inflammation).
   2. TPHA, negative VDRL (performed after the 1st episode of ocular inflammation).
   3. Serologies HIV, HBV and HCV, negative (performed within the 3 months before inclusion).
   4. Negative Lyme serology (performed after the first episode of ocular inflammation) or medical history not supporting this etiology
   5. HLA B27 negative (achieved after the first episode of ocular inflammation) if recurrent or non-granulomatous uveitis
   6. Negative PCR from anterior chamber fluid for Herpes group viruses, Toxoplasma gondii and Mycobacterium tuberculosis if severe inflammation (Tyndall Cellular and / or Flare> 2+) and / or posterior synechiae .
   7. Non-contributory pulmonary imaging (performed within the last month before inclusion) (radiography or chest CT scan left to the discretion of the clinician).

   Note: The non-granulomatous character uveitis during clinical examination is not an exclusion criterion.

7. If 4+ severity score (Tyndall and / or Flare of aqueous humor) an expert opinion is required (internist / ophthalmologist pair): with no indication to initiate an anti-tuberculosis treatment without delay.
8. Signature of informed consent to participate in the study.
