The aging proces is unique in each individual, and although the specific results of that process cannot be predicted with accuracy, the majority of individuals will experience alterations in their sensory organs as they age. In addition to normal (ie, expected) age-related changes, pathologic changes may take place as well.

As the number of somewhat old surgical patients continues to increase, perioperative supply with nourishments often will care for patients with age-related sensory losse Sensory organs provide individuals expressive and receptive communication links with the outside world. With sensory los however, communication may be altered. thus affecting somewhat old patients, abilities to receive and rejoin to information. It is important for perioperative festers to be aware of any sensory losse their somewhat old patients may have. Communication with somewhat old surgical patients is essential to perform accurate patient assessments and to identify perioperative nursing diagnoses. Challenges in the assessment and management of somewhat old patients with sensory losses (eg vision, hearing, get scent of taste, touch, pain sensitivity exist in all phases of perioperative care.

CHANGES IN VISION

Changes in vision are the greatest in quantity common health complaints of adults more than 40 years of age. Age-related structural changes in the notice cause functional changes.

Presbyopia. Decreased accommodation (ie, the ability of the len to change in thickness to focus clearly forward close objects) is one of the more general degenerative changes associated with aging. Presbyopia (ie, antique eye is generally the name used to describe this condition.(2)

Several factors contribute to impaired organ of sight accommodation. The lens enlarges, becomes more firm and opaque, and squanders elasticity as it ages. The ciliary muscles, which detain the lens, become weaker and more relaxed, which, in incline differently affects the lens curvature and models the pupil diameter. Additionally, the surface of the cornea flattens and thickens and its make becomes rougher. With these structural changes, the individual's ability to focus clearly and to change focus from far to near and near to far is impaired, and astigmatism (ie, light rays do not focus onward a single point in the retina because of unequal curvatures of the cornea) increases.

Difficulty with light/dark adoptation. Difficulty with light/dark adaptation present itselfs because of decreased pupil size. Atrophy of the iris and unruffled muscle fiber thickening and rigidity contribute to pupillary miosis (ie, contraction). A smaller and narrower pupil wants more light to function strictly To see accurately, elderly individuals ne three times as a great deal light as 20-year-olds.(3) Making the transition from a dark to light environment or vice versa is difficult for somewhat advanced in life patients.

Decreased color discrimination and stillness perception. Normal age-related yellowing of the len decreases color discrimination and deepness perception. Elderly patients may have difficulty in identifying unimpassioned colors (eg, blue, green, violet. Changes in the len along with the narrowing of the pupil, however, make it easier for somewhat old persons to identify warm colors (eg r orange, yellow)(4)

Increased sensitivity to glare. The increased opacity of the len increases sensitivity to glare. Light strikes the opaque areas of the len causing scattering of the light rays and resulting in glare.

Decreased visual field. The combined structural changes in somewhat old patients, eyes all contribute to decreased visual fields. befitting to opacity of the len miosis of the pupil, and changes in the cornea, visual fields and peripheral vision are altered with age.

Reduc fear production. Reduc tear production causes many somewhat old patients to have dry organ of sights Although this age-related change does not affect vision, it may be bothersome for patients.

Pathologic disorders. Perioperative feed at the breasts commonly see four pathologic disorders of vision in somewhat advanced in life patients. These are cataracts, glaucoma, senile macular degeneration, and diabetic retinopathy.(5) Cataracts are dismal or opaque areas in the len that cause decreased visual acuity, blurr vision, glare, and decreased color perception. Glaucoma is characterized by dint of increased intraocular pressure, leading to los of peripheral vision, central vision, and blindness. Senile macular degeneration causes blurr vision and progressive los of vision. Diabetic retinopathy consists of vascular changes in the retina that lead to retinal detachment and blindness. All of these conditions may bear varying degrees of visual deficits.

HEARING

Ten percent of adults 65 to 75 years of age and 25% of those older than 75 years of age have a hearing loss(6) The in the greatest degree severe changes occur in the inner ear, which is responsible for sensitivity to perfect understanding of speech, arid maintenance of equilibrium. by means of a combination of degeneration and atrophy of the cochlea, organ of Corti, and stria vascularis and los of cortical auditory neuron somewhat old patients may experience deficits in hearing, balance, and tongue communication.
