Anatomy of the Eye

• The iris is the colored part of the eye that controls the size of the pupil and regulates the amount of light entering the eye.
• Anterior Chamber: The space between the cornea and the iris.
• Central retinal blood vessels: arteries that supply the retina with oxygenated blood. Drains blood from the capillaries of the retina into the ophthalmic vein or Cavernous vein.
• Choroid: The layer of the eye that contains the blood vessels and nerves.
• Ciliary Body: A structure that contains the ciliary muscles and suspensory ligaments.
• Ciliary Muscles: Contracts to change shape of lens, allowing light to focus on retina
• Ciliary Process: The movement of the ciliary muscles that changes the shape of the lens. Secrete nutritions to nourish the lens, cornea, and vitreous body.
• Cornea: transparent layer of the eye that refracts light to focus it on the retina.
• Fovea Centralis: Thinned out are of retina that consists of receptor cells, high acuity.
• Lens: A transparent structure that refracts light and focuses it on the retina. (Directly behind the pupil)
• Limbus: The outermost edge of the cornea, where the cornea meets the sclera.
• Optic disc area: Point of exit of ganglion cells leaving the eye (Physiological Blind spot of each eye)
• Optic nerve: carries impulses from the retina to the brain
• Orra serrata: Serrated junction between the retina and ciliary body, non photosensitive region to photosensitive region
• Vitreous Chamber: The space between the lens and the retina.
• Pupil: The opening in the center of the iris that allows light to enter the eye. (Dark chamber behind it)
• Retina: The light-sensitive layer at the back of the eye.
• Schlemm's Canal: A canal that drains aqueous humor from the anterior chamber of the eye.
• Sclera: tough, white, and fibrous part of the eye that surrounds the iris and protects the eye
• Suspensory Ligaments: Long ligaments that connect the lens to the ciliary body.
• Vitreous Chamber: The space between the lens and the retina that contain vitreous humor. Anterior, posterior, and vitreous chambers.
