Normal Eye

• The anterior chamber is the area bounded in front by the cornea and in back by the lens, and filled with aqueous.
  
  
• The choroid , which carries blood vessels, is the inner coat between the sclera and the retina.
  
  
• The conjunctiva is a clear membrane covering the white of the eye (sclera).
  
  
• The cornea is a clear, transparent portion of the outer coat of the eyeball through which light passes to the lens.
  
  
• The iris gives our eyes color and it functions like the aperture on a camera, enlarging in dim light and contracting in bright light. The aperture itself is known as the pupil.
  
  
• The lens helps to focus light on the retina.
  
  
• The macula is a small area in the retina that provides our most central,
  acute vision.
  
  
• The optic nerve conducts visual impulses to the brain from the retina.
  
  
• The posterior chamber is the area behind the iris, but in front of the lens, that is filled with aqueous.
  
  
• The pupil is the opening, or aperture, of the iris.
  
  
• The retina is the innermost coat of the back of the eye, formed of
  light-sensitive nerve endings that carry the visual impulse to the optic
  nerve. The retina may be compared to the film of a camera.
  
  
• The sclera is the white of the eye.
  
  
• The vitreous is a transparent, colorless mass of soft, gelatinous material filling the eyeball behind the lens.
