are you asking about the night time glow in the eyes? well I'm using a cat as an example. they have this structure positioned at the back of the retina called the tapetum lucidum. it works like a mirror, it reflects the light coming into the eye, back out to light sensor cells in the retina, this is what causes the glow.
Tapetum
Coats disease happens when the blood vessels of the retina develop abnormally. Its symptoms are loss of vision and detachment of the retina, and these can happen in one or both eyes.
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.
mucus
Surfactant
The eye. The retina coats the back - inside of the eyeball. It is where all the photosensitive cells reside. It is a flat black colourl
A lining made of mucus.
The substance that coats B cells is called antibodies or immunoglobulins. These proteins are produced by B cells and play a crucial role in the immune response by binding to specific antigens to help neutralize or eliminate pathogens.
It contains a fast setting glue-like substance that coats and stiffens the hair.
Sheep have the same coats to their eyes as humans do. Light passes through the conjunctiva and cornea, crosses the anterior cavity to reach the lens, goes through the lens, crosses the posterior chamber, and then gets to the neural tissue of the retina before reaching and stimulating the photoreceptors.
retinal breaks or detachments; retinal ischemia (retinal tissue that lacks oxygen); neovascularization (proliferation of blood vessels in the retina); Coats' disease
Burmilla cats have coats that can be white, silver, black, brown, blue, or tan.
