This document defines and describes common abbreviations and terms used in ophthalmology and otolaryngology. It explains pressure equalizing tubes (PE tubes) which are surgically implanted to drain ear fluid, and the eye, ear, nose and throat medical specialty (EENT). Additional terms defined include bone conduction (BC), otitis media (middle ear infection), emmetropia (normal vision), extropia (outward eye turn), left eye (OS), extraocular movements (EOM), and visual acuity (sharpness of vision).

Abbreviations of the Eye and Ear Megan Moran S
PE Tube: Pressure Equalizing Tube S Small tube S Surgically implanted into child’s eardrum to assist in draining trapped fluid S Equalizes pressure between middle ear and outside atmosphere
EENT: Eyes, Ears, Nose and Throat S EENT often refers to a physician or office where the physicians specialize in diagnosing and treating the eyes, ears, nose, and throat
BC: Bone Conduction S Bone conduction is the conduction of sound to the inner ear through the bones of the ear S 3 ear bones: S Malleus S Incus S Stapes S BC is why people’s voices sound differently recorded than when they hear themselves talk S The skull conducts better at lower frequencies than air S People usually perceive their voice to be lower and fuller
AU: Both Ears
OM: Otitis Media S Middle Ear Infection/ Inflammation S Commonly seen in children S Fluid accumulation in the ear cavity that may be watery or full of pus S Symptoms Include: fever, Normal Middle Ear VS. Infected Middle Ear ear pain, and a feeling of fullness in the ear
EM:Emmetropia S State of normal vision S Rays of light that enter the eye focus properly at the retina S No need for corrective lenses or surgery
XT: Extropia S Outward turns outward due to muscle weakness S Also called wall-eyed S Opposite of cross- eyed Extropia of the Left Eye
OS: Left Eye
EOM: Extraocular Movement S Eye movements controlled by muscles innervated by cranial nerves III, IV and VI. S Testing these eye movements looks for damage to the nerves S Most common symptom from damage is double vision
VA: Visual Acuity S The measurement of the sharpness of vision S Tested by using a Snellen chart S Patient stands 20 feet away from chart and indentifies letters from that distance
