Eye Anatomy Layers

Eye Anatomy Layers. Human eye is spherical about 2.5 cm in diameter. These chemical changes set off nerve impulses which travel along the optic nerve to the brain.

The outer layer called the fibrous tunic, which consists of the sclera and the cornea; The tarsal plate bears the meibomian glands. Muscles responsible for moving the eyeball are attached to the eyeball at the sclera.

The iris is the colored part of the eye that regulates the amount of light entering the eye. The eye’s lacrimal gland sits under the outside edge of the eyebrow (away from the nose) in the orbit.

The spaces within the eye are filled with fluids that help maintain its shape. In donor eyes from eye banks, the bubble can be inflated to pressure about 700 mmhg before it ruptures.

There Are No Keratocytes In This Layer, And It Is Impervious To Air.

At the front of the eyeball, the sclera becomes the cornea. Rods and cones are the two types of photoreceptor cells in the human eye. Together, the cornea and the lens behind it focus light onto a layer of sensory cells at the back of the eye.

The Sclera (Fibrous Layer) Choroid Layer;

The sclera and the cornea are continuous with each other. The corneal endothelium is only a single layer of cells thick and measures about 5 microns. These three layers together are called the tear film.

It is situated on an orbit of skull and is supplied by optic nerve. This is the innermost layer of the cornea. In donor eyes from eye banks, the bubble can be inflated to pressure about 700 mmhg before it ruptures.

It Contains The Central Thick Part (Tarsal Plate) And The Peripheral Thin Part (Septum Orbitale).

The fibrous layer provides a structural framework to the eyelid. Their main functions are to provide shape to the eye and support the deeper structures. Eye anatomy key structures and pathologically relevant principles.
