Birdshot Chorioretinopathy

**Definition:** A form of chorioretinitis characterized by multiple small, cream-colored LESIONS, symmetrically scattered mainly around the OPTIC DISK. These lesions are the most distinctive sign and often appear at the level of the RETINAL PIGMENT EPITHELIUM but, on occasion, suggest an even deeper infiltration and may ultimately lead to visual loss. An association with HLA-A29 antigen (see HLA-A ANTIGENS) has been observed in nearly all patients.
