2. Case report Birdshot choriorretinopathy since 2006
Visual acuity: RE 20/20 ; LE 20/20
Fundus: Cellophane maculopathy in his right eye; Bilateral white dots
Treatment: Corticoids in the outbreaks and Azathioprine
Without treatment since 2013

5. Case report
August 2016 Emergencies: Blurry vision and methamorphopsias in his right eye
Visual acuity: RE 20/40 LE 20/20
No tyndall, no flare
Fundus: Macular scar.
OCT: Hyper-reflective material in the subretinal space with intraretinal fluid and increase of the thickness of the temporal perifovea
AGF: Hiperfluorescence in early stages with increase of the hyperfluorescence in later stages

8. Evolution Diagnose: Neovascular membrane in Birdshot chorioretinopathy
Treatment: Intravitreous ranibizumab
No other treatment was needed in the following reviews
Actual visual acuity: 20/20 BE
VA: 20/40
VA: 20/20

9. Discussion
Retinal neovascularization may develop in the absence of capillary ischemia in patients with posterior uveitis (1,2)
OCT-angiography: ischemia + inflammation may play a role in the pathogenesis of BCR and the development of complications (3)
Intravitreal anti-vascular endothelial growth factor injections may be an effective treatment along with or without immunosuppressive therapy (4,5)
Inflammation play an important role in this kind of membranes (1,2,3,4)
Rouvas et al. reported a complete remission of CNV secondary to multiple evanescent white dot syndrome in a patient after only one ranibizumab intravitreal injection (5)

10. Take home message
Remark the difference between the reactivation of the disease and a vascular complication, such as CNV
VEGF was effective and no other treatment was needed
Proper studies are needed to establish the therapeutic regime and long term outcomes
