Birdshot chorioretinopathy presents diagnostic challenge

Editors Note: Birdshot chorioretinopathy (BSCR) is an uncommon, but potentially serious, inflammatory disorder that involves both the choroid and retina. No systemic associations have been observed consistently to date. While a strong association with the HLA-A29 class I antigen suggests a genetic predisposition, the vast majority of HLA-A29-positive patients never develop BSCR, and the trigger in that small proportion of HLA-A29-positive patients that does develop the disease is unknown.
