    Uvea

    «Back to the glossary index

    The uvea, also called the uveal tract or vascular tunic, is the middle layer of the eye and is made up of important structures such as the iris, ciliary body and choroid.

    The iris is a vascular membrane and one of the parts of the human body with the largest number of blood vessels, a property that makes it very prone to infections and inflammatory processes.  

    The conditions that can alter the uvea can be congenital, degenerative or traumatological, treating them in time is vital to preserve visual health.

    En Área Oftalmológica Avanzada We explain below what the uvea is and what its function is. 

    What is the uvea of ​​the eye? 

    The uvea is the middle layer of the ocular structure where the choroid, ciliary body and iris are located.

    Together, all of these structures form a pigmented layer below the sclera, the white part of the eyeball. 

    In the uveal tract we find the tissue where the largest number of blood vessels in the human body are grouped, this makes the middle layer of the eye prone to developing infections and inflammatory processes. 

    There are different alterations that can affect the uvea,
