Description : Birdshot chorioretinopathy (BSCR) is characterized by multiple small, cream-colored
lesions, symmetrically scattered mainly around the optic disc and radiating toward
the equator. These depigmented spots, the most distinctive sign of the syndrome, appear
at the level of the retinal pigment epithelium but, on occasion, suggest an even deeper
infiltration. The retinal vasculopathy and inflammatory signs associated with the
funduscopic findings lead regularly to visual loss. Szpak et al. (2001) noted that
the human MHC class I specificity HLA-A29 (see 142800) had been observed in nearly
all patients (95.8%) with BSCR compared with 7% in healthy controls.;
