Posterior Uveitis Birdshot

Hla a29 is a strong genetic risk factor and the disease has been hypothesized to be due to an autoimmune response to retinal s antigens.

Posterior uveitis birdshot. He or she may refer you to an eye. Birdshot chorioretinopathy or birdshot retinochoroidopathy. The disease occurs in women more often than men typically caucasian and most often between the ages of 30 and 60. Posterior uveitis affects a layer on the inside of the back of your eye either the retina or the choroid.

It is believed to be an autoimmune disease. Contact your doctor if you think you have the warning signs of uveitis. Uveitis means inflammation of the uvea. In the early stages of disease patients often report only mild symptoms and there may be a significant delay in diagnosis.

Birdshot chorioretinopathy now commonly named birdshot uveitis or hla a29 uveitis is a rare form of bilateral posterior uveitis affecting both eyes. Posterior uveitis also known as choroiditis refers to inflammation of the choroid the back part of the uvea. Posterior uveitis may affect the retina and or the optic nerve and may lead to permanent loss of vision. Posterior means that it affects the back of the eye.

Birdshot chorioretinopathy is a relatively uncommon subtype of idiopathic posterior uveitis with distinct clinical characteristics and a strong genetic association with the human leukocyte antigen hla a29 allele. Birdshot retinochoroidopathy is a chronic intraocular inflammatory disease affecting mainly the posterior segment of the eye. Usually shortened to birdshot uveitis or birdshot is a rare potentially sight threatening chronic posterior uveitis which usually affects both eyes. Birdshot chorioretinopathy bcr is a bilateral autoimmune posterior uveitis with a distinct clinical phenotype and a strong association with hla a29.

Abstract purpose and methods. Birdshot retinochoroidopathy commonly referred to simply as birdshot is a rare form of posterior uveitis which mainly affects the retina and choroid. Affected individuals are almost exclusively caucasian and usually diagnosed in the fourth to sixth decade of their lives. It causes severe progressive inflammation of both the choroid and retina.

Posterior uveitis is the rare form of the disorder and is the type of uveitis most associated with loss of vision. Chronic means that it lasts a long time. Birdshot is a rare potentially blinding chronic posterior uveitis which usually affects both eyes. Birdshot retinochoroidopathy also known as birdshot chorioretinopathy vitiliginous chorioretinitis or simply birdshot uveitis is a chronic bilateral posterior uveitis with characteristic yellow white lesions in the fundus.

It is distinct from other forms of posterior uveitis because of a very characteristic clinical presentation and a strong association with hla a29 2 antigen. The part of the eye that is made up of the iris the choroid layer and the ciliary body. Birdshot can be a severe and blinding disease if unrecognized or undertreated.
