The '''uvea''' ([[Latin|Lat.]] ''uva'', grape), also called the ''uveal layer'', ''uveal coat'', ''uveal tract'', or ''vascular tunic'', is the middle of the three concentric layers that make up an [[eye]]. The name is possibly a reference to its 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.
