  Purpose

Birdshot Retine choroidopathy (BRC) is a sight threatening posterior uveitis. The long term visual outcome has recently be studied showing a legal blindness to 14% at 5 years. Visual acuity is threatened by macular edema (80%), macular atrophy, and choroidal neovascularization.

Detailed Description:

Birdshot Retine choroidopathy (BRC) is a sight threatening posterior uveitis. The long term visual outcome has recently be studied showing a legal blindness to 14% at 5 years. Visual acuity is threatened by macular edema (80%), macular atrophy, and choroidal neovascularization.

The conventional therapy includes in first line steroid therapy of which side effects are well known. If the daily steroid dose necessary to control the intra ocular inflammation is superior to 0.3 mg/kg/d a combined therapy to immunosuppressive drug is suggested in order to do a steroid sparing effect. Immunosuppressive drugs include increased infectious risks, hematologic and sterility troubles, and secondary malignancies. Moreover immunosuppressive drugs have a own toxic effect and The classical immunosuppressive drug used in BRC the cyclosporineA has a high level of nephrotoxicity.

That is the reason why immunomodulatory drugs as interferons have been suggested in BRC.

Interferon alpha2 a has been shown efficient in uveitis in Behcet's disease. We propose to analyse the potential therapeutic effect of Interferon alpha2 a versus Steroid therapy with a control group for a 4 months period. This short period could not make the disease worse because of the slow pathologic processus.
