Description: The uvea is the middle layer of the eye, consisting of the iris, ciliary body, and choroid. This structure is fundamental for visual function, as it plays a crucial role in regulating the light entering the eye and producing aqueous humor. The iris, the visible part of the uvea, is responsible for the eye’s coloration and controls the size of the pupil, adjusting to lighting conditions. The ciliary body, located behind the iris, not only aids in focusing the eye by accommodating the lens but also produces aqueous humor, a fluid that nourishes and maintains intraocular pressure. The choroid, situated between the retina and the sclera, is composed of a rich network of blood vessels that supply nutrients to the retina and help absorb light that is not captured by photoreceptors. Therefore, the uvea is essential not only for vision but also for protecting the internal structures of the eye and contributing to its overall health. Its integrity is vital, as various pathologies can affect this layer, leading to significant visual problems.
