Birdshot retinochoroidopathy is a clinically distinct pattern of posterior segment inflammation of presumed autoimmune etiology.
The characteristic spots of depigmentation, usually cream-colored at the level of the retinal pigment epithelium or deeper, are the most distinctive sign of birdshot retinochoroidopathy. The lesions radiate outwards from the disc in a linear pattern that seems to follow the choroidal vessels.
The differential diagnosis includes other entities that produce a chronic mild to moderate bilateral panuveitis with choroidal infiltrates. Studies have demonstrated that more than 90% of patients with Birdshot Retinochoroidopathy have HLA-A29 and may be an indicator for evaluation and diagnosis of the disease in patients with suggestive ocular symptoms.
