A closely related condition is multifocal serpiginoid choroiditis. This is caused by tuberculosis. [3] The distinction between these two conditions is important as the latter responds to anti tuberculosis treatment while the former does not. Choroidal neovascularization (CNV) is the most common complication associated with Serpiginous choroiditis.
Polypoidal choroidal vasculopathy (PCV) is an eye disease primarily affecting the choroid. It may cause sudden blurring of vision or a scotoma in the central field of vision . Since Indocyanine green angiography gives better imaging of choroidal structures, it is more preferred in diagnosing PCV.
Choroideremia (/ k ɒ ˌ r ɔɪ d ɪ ˈ r iː m i ə /; CHM) is a rare, X-linked recessive form of hereditary retinal degeneration that affects roughly 1 in 50,000 males. The disease causes a gradual loss of vision, starting with childhood night blindness, followed by peripheral vision loss and progressing to loss of central vision later in life.
The choroid, also known as the choroidea or choroid coat, is a part of the uvea, the vascular layer of the eye. It contains connective tissues , and lies between the retina and the sclera . The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm. [ 1 ] The choroid provides ...
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. If only the choroid is inflamed, not the retina, the condition is termed choroiditis. [1]
Generally, diseases outlined within the ICD-10 codes H30-H36 within Chapter VII: Diseases of the eye, adnexa should be included in this category. Wikimedia Commons has media related to Disorders of choroid and retina .
Birdshot chorioretinopathy is thought to be an autoimmune disease. The disease has strong association with the human leukocyte antigen haplotype (HLA)-A29, which is the strongest association between a disease and HLA class I documented (>99% of patients are HLA-A29 positive by molecular testing and HLA-A29-negative cases are controversial [1]).
The disease is usually unilateral and not associated with any accompanying systemic diseases. [ 3 ] Choroidal vascular disorders which cause visual symptoms, including central serous chorioretinopathy (CSCR), choroidal neovascularization (CNV), and polypoidal choroidal vasculopathy (PCV) may also present with focal choroidal excavation.
