S/sx of hearing loss

May c/o others' mumbling, lean toward the speaker or turn one ear toward the speaker, fail to follow directions, speak while others are speaking, or turn the radio or tv up very loudly.

Choroid

The medication causes the pupil to constrict and will lower the pressure in the eye."

Optic nerve

The nerve that carries neural impulses (visual messages) from the eye to the brain.

Audiometry

The use of an audiometer to measure hearing acuity. Can also do a whisper test to check gross assessment of hearing.

Normal position of the auricle

Top of auricle should be at the approximate level of the eye. Ears should be symmetrical.

Key points for eye irrigation

Wear gloves and clean the eyelids and eyelashes. Position so that the affected eye is "down."

Patient teaching for eyes and vision

Younger than 40, eyes should be checked q 3 - 5 years.
