2. ABBREVIATIONS
Many medical terms have abbreviations that are universally accepted and
used for
convenience. The following slides cover abbreviations related to the
special senses.
The abbreviations are listed in orange.

3. EYE, EAR, NOSE AND THROAT
Eye
Ear
Nose
Throat

4. RIGHT EYE/OD RI LEFT EYE/OS
BOTH EYES/OU

5. EXTRAOCULAR MOVEMENT/EOM
Extraocular movements are controlled by six extraocular muscles, four rectus
muscles and two oblique. These muscles allow us to move the eye up, down and
from side to side.

6. VISUAL ACUITY/VA
Sharpness of a patient’s vision. This
is often measured by using a Snellen
chart.
EMMETROPIA/EM
State of normal vision.

7. EXOTROPIA/XT ESOTROPIA/ST
A. Esotropia is when the eye turns inward
B. Exotropia is when the eye turns outward
Both are examples of strabismus and is caused
by weakness in the extraocular muscles

8. RIGHT EAR/AD LEFT EAR/AS
BOTH EARS/AU

9. PRESSURE EQUALIZING TUBE/PE TUBE
A small tube
surgically
inserted into
an eardrum
to help
equalize
pressure and
assist in
draining
trapped fluid.

10. BONE CONDUCTION/BC
The conduction of sound to the inner ear by the bones in the skull.

11. OTITIS MEDIA/OM
Normal Inflamed
Otitis Media is commonly known as a middle
