Corneal cross-section imaged by an SD-OCT. The human cornea has five layers (possibly six, if the Dua's layer is included). [8] Corneas of other primates have five known layers. The corneas of cats, dogs, wolves, and other carnivores only have four. [9] From the anterior to posterior the layers of the human cornea are:

Iris Gonioscopy of the anterior chamber angle Anterior chamber angle cross-section imaged by an SD-OCT. The trabecular meshwork is an area of tissue in the eye located around the base of the cornea , near the ciliary body , and is responsible for draining the aqueous humor from the eye via the anterior chamber (the chamber on the front of the ...
The front part is also called the anterior segment of the eye. The eye is not shaped like a perfect sphere; rather it is a fused two-piece unit, composed of an anterior (front) segment and the posterior (back) segment. The anterior segment is made up of the cornea, iris and lens.
The corneal endothelium is a single layer of endothelial cells on the inner surface of the cornea. It faces the chamber formed between the cornea and the iris. The corneal endothelium are specialized, flattened, mitochondria-rich cells that line the posterior surface of the cornea and face the anterior chamber of the eye. The corneal ...
The diameter is largest at the surface, tapering toward the inner end. At the outer surface, there is a cornea, below which is a pseudocone that further focuses the light. The cornea and pseudocone form the outer ten percent of the length of the ommatidium. The specific organ of ommatidia, or eye units, vary between different organisms.
