2. Abbreviations
PE Tube-Pressure Equalizing Tube
EENT-Eye, Ear, Nose and Throat
BC-Bone Conduction
AU-Both Ears
OM-Otitis Media
EM-Emmetropia
XT-Exotropia
OS-Left Eye
EOM-Extraocular Movement
VA-Visual Acuity
3. PE Tube
Pressure Equalizing Tube
Also known as ear tubes and myringotomy tubes
Used to reduce middle ear infections in people
with recurring ear infections by draining fluid
buildup
Reduces ear infections, may restore hearing and
balance
Placed with a simple surgery where the ear
drum is cut and the tube is placed
4. EENT
Eye, Ear, Nose and Throat
Sometimes combined in medical
practices
Ophthalmology-study of the eye
Otorhinolaryngology-study of the
ear, nose and throat
5. BC
Bone Conduction
Conduction of sound through bones
of the inner ear
Technology formed using bone
conduction helps with those that are
hearing impaired
Can be used to communicate under
water
6. AU
Both Ears
Latin translation is auris uterque
which literally translates to each
ear
7. OM
Otitis Media
Inflammation of middle ear due to
infection
Fluid often accompanies and is
referred to Otitis Media with Effusion
If chronic, PE tubes are inserted in
the ears to prevent infection
8. Em
Emmetropia
State of normal or perfect vision
Cornea sends rays directly to the
retina
Requires no connection with lenses
9. XT
Exotropia
Type of strabismus (muscle
weakness) of the eye
Causes the eye to move outward
Sometimes surgery is needed to
correct it
10. OS
Left eye
Latin translation is Oculus
Sinister
Sinister means left in Latin
11. EOM
Extraocular Movement
Normal movement of the eye
produced by 6 extraocular muscles
Movements are adduction,
abduction, elevation, depression,
intorsion, and extorsion
12. VA
Visual Acuity
Sharpness of vision
VA test is common in eye
examination
Done using a Snellen Chart
