Cataract

Cataract

Description

Cataracts are opaque areas which occur in the normally clear lens of the eye. This condition is frequently diagnosed in person over 70 years of age. As the cataract worsens over time, vision is reduced, distorted, or blocked. Both eyes are affected, usually one more than the other.

Treatment involves surgical removal of the lens so that glasses, contact lenses, or artificially implanted lenses must be used. Vision improves in approximately 95% of all cases.

There seems to be an increasing incidence, which cannot simply be explained away by an aging population, or better diagnosis:

Causes

Aging, causing senile cataracts
Iritis
Traumatic cataracts
Diabetes mellitus
Heredity        
Hypocalcemia
Hypoglycemia        
Toxic cataracts
X-rays        Heat from infrared rays
Systemic medications such as corticosteroids
Congenital predisposition (e.g., maternal rubella or galactosemia, especially if early in pregnancy)

Cataracts can result as a complication of other eye disorders, such as:
Uveitis
Glaucoma
Retinitis pigmentosa
Detached retina

Signs & Symptoms

General deterioration of vision
Gradual and painless blurred vision
Halos around lights
Blinding glare from headlights
Poor reading vision
Unpleasant glare and poor vision in bright sunlight

In advanced cases, the following symptoms can occur:
Lens is white, opaque, and readily visible
Painful inflammation
Pressure in the eye

* Please refer to the respective topic for specific nutrient amounts.

Note: All amounts are in addition to those supplements having a Recommended Dietary Allowance (RDA). Due to individual needs, one must always be aware of a possible undetermined effect when taking nutritional supplements. If any disturbances from the use of a particular supplement should occur, stop its use immediately and seek the care of a qualified health care professional.


Dietary Considerations

In most cases, cataracts can neither be prevented nor treated by nutritional management. The exception is cataracts which are due to the consumption of galactose or lactose by galactosemic individuals. These cataracts can be prevented and even reversed by adherence to a Lactose Restricted Diet. Pregnant women who are galactosemic or asymptomatic carriers of the trait can prevent congenital cataracts in their children by strictly following a Lactose Restricted Diet.

Quality drinking water is a high priority.

Spinach may have a protective effect.

Homeopathic Remedy

Treatment of choice - Silicea        use 15C for months

1.* Cineraria maritima        30C use per as and as eyedrops (homeopathic or tincture). Must use for several months

2.* Naphthalinum                3X to 30C - use 3X long term (many months) or 30C for 6 weeks

3. Quassia amara (Picraena excelsa)        3C to 30C long term

Treatment Schedule

Doses cited are to be administered on a 3X daily schedule, unless otherwise indicated. Dose usually continued for 2 weeks. Liquid preparations usually use 8-10 drops per dose. Solid preps are usually 3 pellets per dose. Children use 1/2 dose.

Legend

X = 1 to 10 dilution - weak (triturition)
C = 1 to 100 dilution - weak (potency)
M = 1 to 1 million dilution (very strong)
X or C underlined means it is most useful potency

Asterisk (*) = Primary remedy. Means most necessary remedy. There may be more than one remedy - if so, use all of them.

Herbal Approaches

----------
Herbs
-----------


Bilberry
Cayenne (Capsicum annuum)
Cineraria maritima (Dusty Miller)
Curcumin
Eyebright (Euphrasia officinalis)

Note: The misdirected use of an herb can produce severely adverse effects, especially in combination with prescription drugs. This Herbal information is for educational purposes and is not intended as a replacement for medical advice.

Discussion:

Bilberry may be protective against cataracts due to the antioxidant effects of its anthocyanosides. In one study (Bravetti, 1989) a combination of bilberry and vitamin E stopped progression of cataracts in 97% of cases.

Cineraria maritima is a time honored treatment for cataract, with both homeopaths and naturopaths. Eyedrops may be painful. They may be diluted with saline to improve compliance.

Curcumin also has antioxidant properties. It seems to increase the levels of glutathione S-transferase. (Awasthi, 1996)

Eyebright is used in the form of an eyewash.
