adrenaline (epinephrine). A hormone of the adrenal medulla which, instilled in the eye, causes a constriction of the conjunctival vessels, dilates the pupil and diminishes the intraocular pressure. See adrenergic receptors; ocular decongestant; naphazoline; neurotransmitter; noradrenaline (norepinephrine).
For tinnitus with hearing impairment, press and massage the hollows behind both earlobes and the jawbone directly beneath the ears; and/or press on the gums behind the wisdom teeth with a pencil eraser, or bite down on a wad of cotton in the same location for several minutes. Do this once per day.
Tinnitus, or ringing in the ears, is a continuing perceived sound where no external source is present. It may be in one or both ears. It is considered subjective since only the person who has the condition can actually hear it. Individuals with tinnitus sometimes describe the sound as a high-pitch whistle.
