Birdshot chorioretinopathy, now commonly named birdshot uveitis or HLA-A29 uveitis, [1] is a rare form of bilateral posterior uveitis affecting both eyes. It causes severe, progressive inflammation of both the choroid and retina .
In contrast, white dots appear later in the disease stages of birdshot choroidopathy, serpiginous choroiditis, and acute posterior multifocal placoid pigment epitheliopathy. The white dots in these diseases may be present throughout the entire fundus, larger (50 to 500 μm), and tend to clump together.
Uveitis is an ophthalmic emergency that requires urgent control of the inflammation to prevent vision loss. Treatment typically involves the use of topical eye drop steroids, intravitreal injection, newer biologics, and treating any underlying disease.
Chorioretinitis is an inflammation of the choroid (thin pigmented vascular coat of the eye) and retina of the eye. It is a form of posterior uveitis.Inflammation of these layers can lead to vision-threatening complications.
During treatment with pyrimethamine, leukocyte and platelet counts should be monitored weekly. Folinic acid protects against the decrease in platelets and white blood cells induced by pyrimethamine. Prednisone may be used for 3–6 weeks to reduce macular or optic nerve inflammation and can be started on day 3 of antibiotic therapy.
The etiology of multiple evanescent white dot syndrome is currently unknown but two potential origins have been postulated. Gass, et. al. suggests a virus invades retinal photoreceptors through cell-to-cell transmission via either the ora serrata or optic disc margin. [3]
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Microcephaly lymphoedema chorioretinal dysplasia also known as lymphedema microcephaly chorioretinopathy syndrome [1] is a rare genetic condition associated with: Small head (Microcephaly) Puffy feet (Lymphoedema) Eye problems (Chorio-retinal dysplasia i.e. changes in the retina)
