Chapter 13

  1. 1. CHAPTER 13Ariuntungalag Otgonbayar
  2. 2. Pressure equalizing tube - PE tube• A small cylindric device placed through an incision in the tympanic membrane to relieve problems of the middle ear, such as fluid accumulation or auris media infection caused by eustachian tube dysfunction.
  3. 3. Eye, ear, nose and throat - EENT
  4. 4. Bone conduction - BC• The process by which sound waves are transmitted to the inner ear by the cranial bones without traveling through the air in the ear canal
  5. 5. Both ears - AU
  6. 6. Otitis media - OM• The second most common disease of childhood, after upper respiratory infection (URI). OM is also the most common cause for childhood visits to a physicians office.
  7. 7. Emmetropia - EM• A state of proper correlation between the refractive system of the eye and the axial length of the eyeball, rays of light entering the eye parallel to the optic axis being brought to focus exactly on the retina.
  8. 8. Exotropia - XT• A disorder in which the two eyes do not line up in the same direction, and therefore do not look at the same object at the same time. The condition is more commonly known as "crossed eyes."
  9. 9. Left eye - OS
  10. 10. Extraocular movement - EOM• An examination of the function of the eye muscles. A doctor observes the movement of the eyes in six specific directions.
  11. 11. Visual acuity - VA• Acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain. Visual acuity tests
