2. • Pressure Equalizing Tube – PE Tube
• Eye, Ear, Nose, Throat – EENT
• Bone Conduction – BC
• Both Ears – AU
• Otitis Media – OM
• Emmotropia – EM
• Extropria – XT
• Left Eye – OS
• Extraocular Movement – EOM
• Visual Acuity - VA

3. Small Tube surgically placed in a child’s eardrum to assist in drainage of
trapped fluid and to equalize pressure between the middle ear cavity and the
atmosphere
PRESSURE EQUALIZING TUBE –
PE TUBE

4. Eye, Ear, Nose and throat are
interconnected organs that are vital
parts of several body systems
EYE, EAR, NOSE, THROAT – EENT

5. Bone conduction is the conduction
of sound to the inner ear through
the bones of the skull
BONE CONDUCTION – BC

6. Refers to both ears
BOTH EARS – AU

7. any inflammation of the middle ear
OTITIS MEDIA – OM

8. Emmetropia is a state in which the eye is relaxed and focused on an object
more than 6 meters or 20 feet away.
EMMETROPIA - EM

9. Exotropia is a form of strabismus
(eye misalignment) in which one or
both of the eyes turn outward
EXOTROPIA - OS

10. Refers to the left eye
LEFT EYE – OS

11. Extra ocular muscles are the six
muscles that control the movement
of the eye. The actions of the six
muscles responsible for the eye
movement depend on the position
of the eye at the time of muscle
contraction.
EXTRAOCULAR MOVEMENT -EOM

12. sharpness of vision, measured by the
ability to discern letters or numbers
at a given distance according to a
fixed standard.
VISUAL ACUITY - VA
