  3. Conjunctiva
    Transparent mucous membrane that lines each lid and continues over the surface of the eyeball
  4. Cornea
    Clear part of the eye located in front of the iris
  5. Glaucoma, angle closure
    Sudden increase in intraocular pressure caused by obstruction of the drainage portal between the cornea and iris (angle) that can rapidly progress to blindness
  6. Glaucoma, open angle
    Disorder characterized by elevated pressure in the eye that can lead to permanent blindness
  7. Intraocular pressure (IOP)
    Inner pressure of eye. Normal 12-22 mm Hg
  8. Iris
    Colored part of the eye that can expand or contact to allow the right amount of light to enter the eye
  9. Keratotomy
    Incision of the cornea to correct myopia
  10. Lacrimal Apparatus
    Structures that keep the surface of the eye moistened with lacriminal fluid (tears)
  11. Optic Disk
    Oscular end of the optic nerve where the retinal nerve fibers exit and the blood vessels enter
  12. Optic Nerve
    Bundle of nerve fibers located in the back of the eye that connects the retina to the brain
  13. Tonometry
    Use of a device to measure the pressure in the eye
  14. Trabecular Meshwork
    Small opening around the outer edge of the iris that form meshlike drainage canals surrounding the iris. Aka Schlemm's canal
