To explain:

The difference between two conditions and why the treatment for both may appear to be similar.

Concept introduction:

The eye is the most sensitive organ of the body. It helps to provide vision. The eyewall is composed of three layers such as a fibrous tunic, vascular tunic, and retina tunic. Rods and cones cells are the receptor cells that provide clear vision.

George is unclear why nearsighted persons may need bifocal eyeglasses (which have two lenses—one for reading and one for nearsightedness) when they get older. He does not understand why the same set of glasses wouldn’t work for both reading and the nearsighted correction. Can you explain to George the difference between the two conditions, and why the treatment for both may appear to be similar?
Presbycusis is an age-related hearing loss affecting individuals over the age of 65. Many affected individuals have difficulty understanding words because, although they may be able to hear the sound, they are unable to distinguish the exact words. This hearing loss is most noticeable at higher frequencies. Which of the following statements correctly describes an individual suffering from presbycusis? Select one: a. Individuals with presbycusis have damaged hair cells at the base of the cochlea, which is closest to the oval window. b. Increasing the volume of higher frequency sound allows individuals affected with presbycusis to hear better. O c. Individuals with presbycusis have damaged hair cells at the apex of the cochlea, which is farthest from to the oval window. Od. Decreasing the amplitude of lower frequency sound allows individuals affected with presbycusis to hear better.
Ototoxic drugs are drugs that may damage the cochlea, auditory nerve and/or the vestibular system of the ear. The damage caused is usually temporary and symptoms improve once the patient stops taking the drug. However, in some patients, the damage is permanent. Damage to the cochlea is the most common problem associated with these drugs. The reason that hearing loss results when the cochlea is damaged is: Select one: a. The bones in the ear do not amplify or increase the sound vibrations. b. The eardrum cannot transmit vibrations from sound waves to the malleus. c. The Eustachian tube remains open. d. Hair cells within the damaged cochlea do not bend preventing the transmission of an electrical signal to the auditory nerve.
