Peripheral (posterior) vitreous detachment occurs when the gel around the eye separates from the retina. This can naturally occur with age. This can naturally occur with age. However, if it occurs too rapidly, it can cause photopsia which manifests in flashes and floaters in the vision .
Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
Diagnosis. Familial exudative vitreoretinopathy involves the improper growth and development of the blood vessels in the retina. Diagnosis of FEVR is often made through direct visualization of the retina and fluorescein angiography, along with personal and family medical history. Hallmark characteristics of FEVR include lack of blood vessels in ...
Retinal detachment is typically painless, with symptoms often starting in the peripheral vision. [3] [9] [10] Symptoms of retinal detachment, as well as posterior vitreous detachment (which often, but not always, precedes it), may include: [3] [4] [9] [10] [12] Floaters suddenly appearing in the field of vision or a sudden increase in the ...
Prognosis depends on the location of the bleed, the amount of bleeding, the rate of clearing of blood, whether the blood is affecting visual acuity, complications (such as corneal staining, retinal detachment, pre-retinal fibrosis, ischemic optic atrophy, or glaucoma), and the severity of involvement of the macular region.
Vitreomacular adhesion (VMA) is a human medical condition where the vitreous gel (or simply vitreous, AKA vitreous humour) of the human eye adheres to the retina in an abnormally strong manner. As the eye ages, it is common for the vitreous to separate from the retina.
Both conditions share similar symptoms, such as progressive vision loss, night blindness, and blind spots. However, they have different underlying causes. RP is a hereditary disorder caused by mutations that lead to the degeneration of photoreceptor cells, typically starting with peripheral vision loss and progressing to central vision loss ...
Primary sites of inflammation include the vitreous of which other such entities as pars planitis, posterior cyclitis, and hyalitis are encompassed. Intermediate uveitis may either be an isolated eye disease or associated with the development of a systemic disease such as multiple sclerosis or sarcoidosis. As such, intermediate uveitis may be ...
