An Amazing Structure that Creates Your Window To The World

EXAMINING THE INTERIOR OF THE EYE: Your eye is a specialized sense organ capable of receiving visual images,  busily absorbing light and energy that brings you vision. If you’d like to know more about what’s in your eye, this brief synopsis can help. Any additional questions, just ask Dr. Plous.

  • Sclera – Supporting structure of the eye made up of connective tissue. The sclera connects with the cornea, and is called the “white” of the eye.
  • Iris– The colored part of the eye that controls the amount of light that reaches the retina. The iris does this by controlling the size of the pupil.
  • Pupil– The opening within the Iris that allows light to pass into the eye. The larger it is the more light enters the eye.
  • Cornea– The clear front part of the eye that connects with the sclera and serves as the primary refractive structure of the eye. This is the window into the eye.
  • Lens – A structure composed of proteins that changes shape to focus light on the retina.
  • Vitreous Gel– The optically transparent gelatinous substance that fills the area between the lens and retina. The vitreous helps maintain the eye’s shape.
  • Retina– The light sensitive inner lining of the back of the eye. The retina converts light into electrical signals that are then transmitted to the brain through the optic nerve.
  • Optic Nerve– Located at the back of the eye, it transmits electrical signals created by the retina to the brain where they are experienced as images.
  • Macula– The central area of the retina that provides your central vision. You use your macula when you are viewing something straight ahead. The structures and cells within the macula are responsible for highly detailed, sharp, vision.
  • Fovea– Located in the center of the macula and the area where fine vision and color perception are the greatest.
  • Retina Blood Vessels– Bring oxygen and nourishment to the retina.
  • Choroid– The highly vascular layer between the sclera and the retina that provides oxygen and nourishment to the retina.
