Eye conditions affecting older adults.
|
| Dry Eye: |
is a condition in which the quantity or quality of tears is not sufficient. The patient may have transient blurring of vision, irritation, burning sensation, and sometimes reflex watering from eyes. A test for dry eye helps to decide whether the patient needs lubricant eye drops or a change in dietary variables in order to balance the tear production. Patients most susceptible to dry eye include people with arthritis, computer users, contact lens wearers, women approaching menopause, and people taking antidepressants and beta blockers.
|
| Cataract: |
is clouding of the lens of the eye with age. A good nutritional diet rich in anti-oxidants is often helpful in delaying the progression of cataract.
|
| Macular Degeneration: |
The macula is the most sensitive area in the retina responsible for direct central vision. Any condition which restricts blood flow to the macula over a long period of time can cause it to deteriorate. High blood pressure, diabetes, cigarette smoking, and high cholesterol contribute to atherosclerosis and therefore to macular degeneration. Vitamin A (beta carotene), Vitamin B6, zinc and copper supplements and a diet rich in lutein and zeaxanthin are often helpful. In extreme cases, lasers are recommended.
|
| Diabetic Retinopathy: |
is a condition in which hemorrhages and vascular problems occur in the retina because of a lack of the hormone insulin, or its lack of efficacy at the site of action. Nutritional counseling for control of blood sugar, and regular fundus examinations are the cornerstone of diabetic therapy and the prevention of blindness in diabetics.
|
| Glaucoma: |
is a condition in which the pressure inside the eye is markedly elevated, which prevents the blood from reaching and nourishing the eye. Symptoms include eye pain, red eye, dilated pupils, blurred vision and haloes around lights. The fluid tension in the eyeball is checked to rule out glaucoma. It can be treated medically through eye drops, or by laser or surgery.
|
| Low vision: |
Macular degenerations and other serious eye conditions in later years can cause a decrease in the vision that is not correctable by surgery, medication, or ordinary spectacle lenses. Low vision aids are a solution to these problems. These include hand-magnifiers, stand magnifiers, pocket telescopes, closed circuit televisions, etc.
