Uvea

Uvea is the middle layer of the eye, located between the sclera and the retina. Its main role is to protect the eye from light, radiation, and trauma. It is made up of several layers: the iris, ciliary body, and choroid. The iris is the colored part of the eye, the ciliary body helps the lens to focus and the choroid acts as a blood supply to the eye. Uvea is also important for nourishing other eye structures with blood and oxygen, maintaining normal intraocular pressure, and producing the pigment melanin, which helps to protect the eye from damaging UV radiation. Uvea plays a critical role in normal vision and is important for maintaining overall eye health. Abnormalities in the structure or function of uvea may lead to a range of vision problems, and can be detected through regular eye exams.
