The part of your eye that receives no blood at all is the cornea. This is the clear and transparent part of the eye and it does not have any blood vessels.
The cornea, the clear part of the eye, does not contain blood vessels and it receives oxygen supply directly from the air.
Conjunctiva
The choroid is the vascular layer between the sclera and retina. These blood vessels supply the eye with oxygen and nutrients.
They carry blood. What did you think they did?
The cornea is the part of the eye that is avascular, meaning it does not have blood vessels. Instead, it receives nutrients and oxygen directly from tears on its surface and the surrounding aqueous humor.
Blood vessels in the eye play a crucial role in maintaining good vision and overall eye health. These vessels supply oxygen and nutrients to the eye tissues, including the retina, which is essential for clear vision. When blood vessels in the eye are damaged or blocked, it can lead to vision problems such as blurry vision, loss of vision, or even serious eye conditions like diabetic retinopathy or macular degeneration. Therefore, it is important to keep the blood vessels in the eye healthy through proper eye care and regular eye exams.
The smallest blood vessels in the body are called capillaries.
Eye blood vessels play a crucial role in maintaining the overall health and function of the eye by supplying oxygen and nutrients to the various parts of the eye, including the retina. They also help regulate intraocular pressure and remove waste products, contributing to the proper functioning of the eye. Additionally, the blood vessels in the eye can provide important clues about a person's overall health, as certain conditions like diabetes or hypertension can manifest in the eye through changes in the blood vessels.
The iris.
The sclera.
Vascular Coat or Uvea is the middle part of the wall of the eye. Uvea has a rich supply of blood vessels that provides nutrients of the eye.
There are a few blood vessels that are in the sclera, or white part of our eye, but most of the blood vessels are found in the retina in the inside back of our eye. Blood is not not normally inside the eye itself or it would interfere with the passage of light through the eye.
