Pressure Equalizing Tube Abbreviation- PE Tube Two most common reasons for a PE Tube are because of reoccurring ear infections or a build up of fluid in the ear leading to hearing loss.
Bone conduction Abbreviation- BC BC is the conduction of sound to the inner ear and bones of the skull.
Otitis media Abbreviation- OM Commonly referred to as a middle ear infection Usually proceeded by an upper repiratory infection during which pathogens move from the pharynx to the middle ear. Fluid accumulates in the ear. Children are prone to it because the angle of their Eustachian tube is more horizontal and shorter If infection is cause by bacteria, treatment can be antibiotics. If viral, the infection has to clear up on its own.
Emmetropia Abbreviation EM Means “the state of normal vision”
Exotropia Abbreviation- XT Means outward turning of the eye, wall-eyed. It is a muscle weakness of the eye.
Visual activity Abbreviation- VA Means the measurement of the sharpness of a patient’s vision. A Snellan chart is used for this test in which a patient identifies letters from a distance of 20 feet.
