The tapetum lucidum (reflective material) reflects light back into the retina. This allows the animal to see at night. (Although this allows for better night vision than that of humans, it distorts the clarity because the light is reflected so much.)
The tapetum lucidum is also responsible for the "glowing" eyes of animals, such as cats, when a small amount of light reflects off the tapetum lucidum in an otherwise dark room.
The three coats include: 1) The outer fibrous coat; formed by the cornea and the sclera. 2) Middle vascular coat; which consists of the choroid, ciliary body and the iris. 3) The internal nervous coat; which is the retina.
Damage to the choroid plexus can interfere with the production and regulation of cerebrospinal fluid (CSF), which is essential for cushioning the brain and spinal cord, removing waste, and delivering nutrients. This can result in conditions such as hydrocephalus or altered CSF composition, affecting brain function.
Cerebrospinal fluid is primarily produced by specialized structures in the brain called choroid plexus, rather than capillary knots. These choroid plexus structures filter blood plasma to create cerebrospinal fluid, which serves to protect the brain and spinal cord.
The sclerotic coat is a tough, white layer that surrounds the eyeball. Its function is to provide structural support and protection to the eye, maintaining its shape and preventing it from collapsing.
This is the middle layer of the eyeball and it is composed of the choroid, ciliary body and iris.
The pigmented choroid coat is iridescent because of the tapetum lucidium and its function is that it reflects the light in the eyes and is found only in animal eyes because of low light intensity
Choroid
The choroid, also known as the choroidea or choroid coat, is the vascular layer of the eye, containing connective tissue, and lying between the retina and the sclera. The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm.[1] The choroid provides oxygen and nourishment to the outer layers of the retina. Along with the ciliary body and iris, the choroid forms theuveal tract.

The Choroid Plexus has a main function of filtering, removing waste, and foreign substances. It is also responsible for removing excess neurotransmitters.
The choroid, also known as thechoroideaorchoroid coat, is thevascular layer of the eye, containingconnective tissue, and lying between theretina and thesclera.The choroid providesoxygen and nourishment to the outer layers of theretina.

The three coats include: 1) The outer fibrous coat; formed by the cornea and the sclera. 2) Middle vascular coat; which consists of the choroid, ciliary body and the iris. 3) The internal nervous coat; which is the retina.
The choroid coat is a vascular layer located behind the retina in the eye. It provides nutrients and oxygen to the outer layers of the retina and helps regulate the amount of light entering the eye by absorbing excess light.
