  2. binocular vision
    normal vision involving the simultaneous use of both eyes
  3. fundus of the eye
    the posterior, inner part of the eye that can be directly visualized with an ophthalmoscope
  4. intraocular pressure
    the internal pressure of the eye that is regulated by resistance to the flow of aqueous humor
  5. lens
    • a transparent refracting medium, usually made of glass
    • the crystalline lens of the eye
  6. mydriasis
    a pronounced or abnormal dilation of the pupil
  7. optic nerve
    the cranial nerve that transmits impulses from the retina to the cerebral cortex in the brain
  8. pupil
    dark opening in the center of the iris that regulates the amount of light entering the eye by constricting when light increases, and dilating when light decrease
  9. refraction
    the bending of light rays as they pass through the various structures of the eye to bring the rays into focus on the retina
  10. rhodopsin
    the pigment found in the rods of the retina that adapts the eye to dim light; important in night vision
  11. suspensory ligament
    any of a number of ligaments that help support an organ or body structure, such as the suspensory ligaments inside the eye that hold the lens in tension
  12. vitreous humor
    • clear, jellylike substance that fills the posterior chamber
    • transmits light, contributes to intraocular pressure, helps maintain the shape of the eyeball, and keeps the retina in place
