Uveal disease

The uvea is located between the sclera and the retina of the eyeball, mainly including the iris, ciliary body, and choroid. Because it contains pigment and is colored, resembling a purple grape, it is called the uvea. Uveal diseases are related conditions affecting the uvea, with inflammation being the most common, followed by tumors, and some congenital or degenerative changes. They mainly include the following types of diseases: Uveitis: Clinically, inflammation occurring in the uvea, retina, retinal blood vessels, and vitreous is collectively referred to as uveitis. It primarily affects young and middle-aged adults and is a common and significant cause of blindness. Tumors Benign uveal tumors: Iris cysts, iris nevi, choroidal nevi, and choroidal hemangiomas, etc. Malignant uveal tumors: Malignant melanoma of the iris, malignant melanoma of the choroid, metastatic choroidal carcinoma, etc. Congenital uveal abnormalities Congenital aniridia, iris coloboma, congenital iris cysts. Persistent pupillary membrane, congenital pupillary dyscoria, polycoria. Ciliary body developmental abnormalities. Congenital choroidal coloboma. This disease is more common in young and middle-aged adults, with a higher incidence in males than females. Main symptoms include conjunctival hyperemia, floaters, and blurred vision. Different stages present with different manifestations, which can be localized, disseminated, or diffuse tissue damage.
