● Cataracts
● Glaucoma
● Macular Degeneration
● Diabetic Retinopathy
Decrease in the ability to:
- acknowledge the object
- identify where the touch or pressure is EXTERNAL CANAL
occurring. ● Shrinkage in Cerumen glands
- identify how many objects are touching ● Loss of elasticity of outer ear
the skin ● Narrowing of external ear canal
● Tympanic membrane stiffens
Loss of sensation and proprioception
MIDDLE EAR
● Loss of elasticity of middle ear
● Ossicles Shrink
Hyposmia ● Narrowing of joint space between ossicles
Concerns:
- inability to sell harmful odors HEARING LOSS
- change in eating habits and receive Presbycusis
- less enjoyment from food 4 categories:
1. Sensory Presbycusis
2. Strial Presbycusis
3. Neural Presbycusis
Hypogeusia 4. Cochlear Conductive Presbycusis
- Detection of salt changes most
- Detection of sugar does not appear to
change
CONCERNS: poisoning and malnutrition MAJOR GLANDS:
- Hypothalamus
- Pituitary gland
- Thyroid
Dry eye syndrome - Parathyroid
Functional decline in conjunctiva - Pineal glands
Structural Changes - Adrenal gland
- Decrease transparency in cornea - Reproductive glands
- Decrease ability of pupil and iris to - Pancreas
constrict and dilate
- Lens become less curved and more flat
- Loss of transparency of vitreous humor - Decrease in growth hormone
- Increase in vasopressin
AGE RELATED CHANGES IN VISUAL FUNCTION
● Presbyopia/ Farsightedness
● Sensitivity to contrast - Slight Decrease in T3 and T4
● Corneal Aging - Increase in TSH
● Changes in Visual Field - Decrease in calcitonin
● Impaired Divided Attention
● Impaired color Discrimination
● Glaucoma
● Macular Degeneration
● Diabetic Retinopathy
