Brief Summary

Uveitis accounts for 15% of the causes of legal blindness. The etiological diagnosis of uveitis is difficult because of the poor bacteriological performance of aqueous or vitreous fluid analysis. At the end of a medical and paramedical check-up, oriented by the typology of uveitis, a clinical situation is frequently encountered: idiopathic uveitis with a Quantiferon test (QFN) positive orienting to an old or recent contact with tuberculosis. Ocular tuberculosis is often characterized by a partial and transient response to corticosteroid therapy (local or general), due to predominant hypersensitivity phenomena and low inoculum. Therefore, antitubercular treatment is recommended for idiopathic posterior uveitis with positive QFN. This treatment of 6-9 months has shown, in combination with systemic corticosteroids, its effectiveness on ocular inflammation and significant decrease in recurrence frequency. For previous uveitis with QFN positive, there is no study or recommendation in the low endemic countries on the indication of anti-tuberculosis drugs and practices are variable. Tuberculous anterior uveitis is distinguished by high rate of relapses and chronic uveitis upon discontinuation of topic corticosteroid therapy that exposes to broad posterior synechiae leading to an ocular functional impairment. Optimizing the management of recurrent anterior uveitis is therefore crucial. The aim of this prospective, randomized, controlled, open, two parallel arm trial is to compared antitubercular treatment "add-on "of local corticosteroid therapy to Local Corticosteroid Therapy Only in patients with recurrent or chronic anterior uveitis. Primary outcome is the treatment succes defined as uveitis recovery at 3 months and the absence of recurrence at 18 months of follow-up.

Outcome Measures

Primary Outcomes (1)

  • Success

    Success is defined by uveitis recovery at 3 months and the absence of recurrence at 18 months of follow-up. The intensity of the ocular inflammation will be evaluated using the Standardization of Uveitis Nomenclature (SUN) classification (score of cellular Tyndall and "Flare" of the aqueous humor) Failure is therefore defined as failure to recovery at 3 months of anterior uveitis or recurrence at 18 months.

    at 18 months

Secondary Outcomes (45)

  • Proportion of patients having developped neutropenia

    at 6 months

  • Proportion of patients having developped hepatitis with clinical signs

    at 6 months

  • Proportion of patients having developped severe hepatitis

    at 6 months

  • Proportion of patients having developped moderate or severe skin allergy

    at 6 months

  • Proportion of patients having developped neuritis or optic atrophy

    at 6 months

  • +40 more secondary outcomes

Study Arms (2)

Antitubercular treatment and local corticosteroid therapy

EXPERIMENTAL

Treatment of ocular inflammation by "antitubercular treatment " add-on "of local corticosteroid therapy" comprising: * RIFATER © (Isoniazid + Rifampicin + Pyrazinamide) + Ethambutol (13.5-20 mg / kg / day) for 2 months then RIFINAH © (Isoniazid + Rifampicin) for 4 months * associated with a treatment similar to the control group.

Drug: Antitubercular treatment (RIFATER ©)Drug: EthambutolDrug: RIFINAH ©

Local Corticosteroid Therapy Only

NO INTERVENTION

Treatment of Ocular Inflammation by "Local Corticosteroid Therapy Only" comprising: * Dexamethasone (DEXAFREE® eye drops) at an attack dose for one week (4 to 6 drops / d maximum and if severe inflammation 1 drop / hour) then decrease and stop over 3 weeks, with relay by fluorometholone (Flucon®) for 2 months maximum. The modalities of the decrease of the local steroids are left to the ophthalmologists own judgment. Maximum total duration of 3 months. * Mydriatic (tropicamide) 1gx3 / d if necessary. * Neosynephrine 5% if posterior synechiae. * Atropine (Alcon 0.3%) if pain.

Interventions
