The uvea (Lat. uva grape) also called the uveal layer uveal coat uveal tract or vascular tunic is the pigmented middle of the three concentric layers that make up an eye. The name is possibly a reference to its reddish-blue or almost black colour wrinkled appearance and grape-like size and shape when stripped intact from a cadaveric eye. Its use as a technical term in anatomy and ophthalmology is relatively modern.[citation needed]
