The term 'Iris Area' is a reference to the uvea, which is the middle layer of the eye. It is composed of three parts: the iris, ciliary body, and choroid. The iris is the colored part of the eye that controls the amount of light entering the eye. The ciliary body produces aqueous humor, which helps maintain the shape of the eye. The choroid is a layer of blood vessels that nourishes the retina. Together, these three parts make up the uvea, or Iris Area.
