Vascular tunic. This is the middle layer of the eye and is made up of the
choroid, the ciliary body, and the iris. Altogether, these structures are called the uvea
The choroid is the layer responsible for providing the pigmentation that forms most of the pigmented vascular tunic of the eye. It helps to absorb excess light and prevent reflection within the eye, contributing to visual acuity.
The iris, ciliary body, and choroid are all part of the vascular layer of the eye, also known as the uvea. This layer is located between the retina and the white part of the eye (sclera) and is responsible for nourishing the eye and regulating the amount of light that enters.
The iris is contained within the middle layer of the eye known as the uvea, which includes the choroid, ciliary body, and the iris. The iris is the colored part of the eye that surrounds the pupil and regulates the amount of light entering the eye by controlling the size of the pupil.
The posterior portion of the vascular tunic is called the choroid. It is a layer of blood vessels that supply nutrients and oxygen to the retina. The choroid also helps to regulate the amount of light entering the eye by absorbing excess light.
The three layers of the eye wall are the sclera (outer layer, white and tough), choroid (middle layer, rich in blood vessels), and retina (inner layer, contains light-sensitive cells). Each layer plays a crucial role in protecting the eye and enabling vision.

The mammalian eye can be dividied into three main layers (tunics): fibrous tunic, vascular tunic, and the nervous tunic. The fibrous tunic consists of the cornea and the sclera. The vascular tunic includes the iris, ciliary body, and choroid. The nervous tunic includes the retina. rbb, MD

The iris is contained within the middle layer of the eye known as the uvea, which includes the choroid, ciliary body, and the iris. The iris is the colored part of the eye that surrounds the pupil and regulates the amount of light entering the eye by controlling the size of the pupil.
The Vascular Tunic. Formation of images on the retina include three processes: Refraction of light rays; accommodation of the lens; and constriction of the pupil. The pupil and lens are housed in the Vascular Tunic.
This isn't easy to answer because 'middle layer' is hard to pin point. From the outside front to the back, this is the order, Conjunctiva, cornea, aqueous humor, pupil (with the iris at both sides), lens, vitreous humor, retina, and then the optic nerve. The uvea is the middle vascular layer of the eye. It contains the iris, ciliary body and chorid.
choroid coat.
The eye contains three layers which are: the outer fibrous tunic, an intermediate vascular tunic, and an inner neural tunic (retina). The outer fibrous tunic function is to serve as the sclera and cornea. The cornea serves as a opening to the eye and helps with thefocus of light rays. The sclera protects from large and small particles and provides a connection for extrinsic muscles. The middle vascular tunic consists of three eye structures: choroid coat that helps to consumeexcess light, this is why the inside of the eye is dark and the ciliarry body which createsthe ciliary muscles and processes, and the iris which has smooth muscle controls the pupil size and also the colored part of the eye. The inner nervous tunic contains the retina andthe visual receptor cells. This portion of the eye is made of different cell types like the nerve cell.
The posterior portion of the vascular tunic is called the choroid. It is a layer of blood vessels that supply nutrients and oxygen to the retina. The choroid also helps to regulate the amount of light entering the eye by absorbing excess light.
uvea is the actual vascular layer but its posteriormost part is the choroid coat. so it could be either or really. the iris is the most anterior area though
