saccadic movements of the eyes.

EENT

Eye, ear, nose and throat

OD (Ocular Dexter)

Right eye

OS (Ocular Sinister)

Left eye

HEENT

Head, ears, eyes, nose, throat

BC

Bone conduction Bone conduction is the reason why a

person's voice sounds different to him/her when it is recorded and played back. Because the skull conducts lower frequencies better than air, people perceive their own voices to be lower and fuller than others do.

PE tube

Pressure tube equalizing  a small cylindric device placed through an

incision in the tympanic membrane to relieve problems of the middle ear, such as fluid accumulation or auris media infection caused by eustachian tube dysfunction.

SOM

Serous otitis media Serous otitis media describes a collection of

fluid in the middle ear.

VA

Visual acuity is acuteness or clearness of vision, which is

dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain.
