    • infection of the conjunctiva
  12. Cotton-wool area

  14. OS
    • oculus sinister
    • LEFT eye
  15. OD
    • oculus dexter
    • RIGHT eye
  16. Presbyopia
    • decrease in power of accommodation that occurs with aging
    • farsighted
  17. Ptosis
    drooping of upper eyelid over the iris and possibly covering pupil
  18. Red Reflex
