   More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit visual signals through the optic nerve. [1] A hollow structure, the bulbus oculi is composed of a wall enclosing a cavity filled with fluid with three coats: the sclera, choroid, and the retina. [2] Normally, the bulbus oculi is bulb-like ...

   A human eye demonstrating its owner's rare ability to voluntarily dilate and constrict his pupil on command, via voluntary control of his iris muscles. Anterior chamber cross-section imaged by an SD-OCT. From anterior (front) to posterior (back), the layers of the iris are: Anterior limiting layer; Stroma of iris; Iris sphincter muscle

6. Orbit (anatomy) - Wikipedia

   There are two important foramina, or windows, two important fissures, or grooves, and one canal surrounding the globe in the orbit. There is a supraorbital foramen, an infraorbital foramen, a superior orbital fissure, an inferior orbital fissure and the optic canal, each of which contains structures that are crucial to normal eye functioning.

7. Eye - Wikipedia

   en.wikipedia.org/wiki/Eye

   Eyes can be the most visible parts of organisms, and this can act as a pressure on organisms to have more transparent eyes at the cost of function. [40] Eyes may be mounted on stalks to provide better all-round vision, by lifting them above an organism's carapace; this also allows them to track predators or prey without moving the head. [8]

8. Anterior segment of eyeball - Wikipedia

   en.wikipedia.org/wiki/Anterior_segment_of_eyeball

   The anterior segment or anterior cavity [1] is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. [2] [3] Within the anterior segment are two fluid-filled spaces: the anterior chamber between the posterior surface of the cornea (i.e. the corneal endothelium) and the ...

9. Visual system - Wikipedia

   en.wikipedia.org/wiki/Visual_system

   Light entering the eye is refracted as it passes through the cornea. It then passes through the pupil (controlled by the iris) and is further refracted by the lens. The cornea and lens act together as a compound lens to project an inverted image onto the retina. S. Ramón y Cajal, Structure of the Mammalian Retina, 1900
