Eye Cataract:- Cataract Symptoms, Treatment, Eye Surgery, Removal/ Treatment, Diagnosis, Causes and Home Treatment of Cataract
A cataract is a condition of the eye that makes it difficult to see. It happens when the lens of the eye (the part of the eye that we see through) becomes clouded. The lens is at the front of the eye. It focuses light on the retina, at the back of the eye, to form images. A cataract can affect a small part of the lens, or it may cloud the whole lens.
Cataracts that cloud the whole lens can seriously affect your sight and you may need an operation to prevent you going blind. This is generally a quick and painless operation in which the lens is taken out and replaced with an artificial one.
Cataracts take a long time to form and are most common in older people. Loss of vision is gradual and many people may not realize they have a cataract. Poor sight is a normal part of getting old, but it can be treated and often made better if a cataract is the cause. Opticians can easily spot cataracts, which is why regular eye check-ups are important.
Cataracts cannot be spread from one eye to the other, but they may develop in both eyes at the same time.
The first sign of cataract is blurred vision. The patient finds it difficult to see things in focus. As the cataract progresses, the patient' may get double vision or spots or both. There is gradual increase in blindness. At first, vision in twilight may be better than in full daylight since light is admitted round the more widely-dilated pupil in the dark. In the advance stage, objects and persons may appear merely blobs of light. In the final stage, there is a grayish-white discoloration in the pupil.
Cause of Cataract
Cataract is often found in association with other defects of the eye. There are four factors, which contribute to the loss of transparency of the lens. These are, stagnation of the fluid current in the lens resulting from bad blood condition; deterioration in the nutrition of the lens which diminishes the vitality and resistance of the delicate lens fibres; acid and salt deposits between the lens fibres which have an irritating effect on the lens tissues and exert an increasing pressure on its delicate fibres, gradually destroying them; and disintegratior of the lens fibres, clouding the whole lens in the absence of appropriate measures.
As in case of most diseases, poisons in the blood stream due to dietetic errors and faulty style of living are the real cause of cataract. The toxic matter in the blood stream spreads throughout the body to find shelter in any available weak spot. It strikes the lens if that part has become weak through strain, excessive use of the eyes or local irritation. The condition becomes worse with the passage of time and then a cataract starts developing. Other causes of cataract are stress and strain, excessive intake of alcoholic drinks, sugar, salt, smoking, certain physical ailments such as gastro-intestinal or gall-bladder disturbances, -diabetes, vitamins deficiencies, especially of vitamin C, fatty acid intolerances, ageing, radiation and side-effects of drugs prescribed for other diseases.
Some specialists believe that the most important cause of many cataracts is poor nutrition. This may be true even in case of the type of cataract commonly called senile or ageing cataract. The cause may be a lifetime of malnutrition.
Diagnose of Cataract
To detect a cataract, your ophthalmologist examines your lens. A comprehensive eye examination usually includes the following:
Visual acuity test - An eye chart test that measures your sight at various distances
Pupil dilation - Widening of the pupil with eye drops to allow your ophthalmologist to examine more of the lens and the retina as well as to look for other eye problems
Tonometry - A standard test to measure fluid pressure inside the eye (Increased pressure may be a sign of glaucoma.)
To learn more about the structure and health of your eye, other tests may be performed. These tests may include the following:
Specular photographic microscopy - A test to examine the health of your cornea
Glare testing - A test to see if your cataract causes visually significant glare
Contrast sensitivity testing - A test to check your ability to see "shades of gray"
Potential vision testing - A test that attempts to "bypass" your cataract in order to determine the quality of your vision without it
Cataract Treatment / Removal
No treatment is needed for mild cases of cataracts. If they do not interfere with a patient's vision, they are not treated. If moderate vision problems develop, a stronger eyeglass prescription may be all that is needed.
In more serious cataract cases, surgery may be necessary. Surgery is the only procedure available for treating advanced cases of cataracts. Cataract surgery is relatively simple.
Cataract surgery can be performed in a doctor's office and usually lasts about an hour. The cloudy lens is removed. An artificial plastic lens is then inserted into the space formerly occupied by the damaged lens. The patient is given antibiotics and steroids after the surgery. The antibiotics protect against infection by bacteria. The steroids help reduce the pain and inflammation caused by the surgery.
Cataract is a natural ageing process; there is not much that can be done to prevent their development. Wearing dark glasses in direct sunlight may be helpful. Radiation from the sun is thought to be one possible cause of changes in proteins in the lens. A healthy diet rich in citrus fruits, sweet potatoes, carrots, and green leafy vegetables, and supplemented by vitamins, may also be helpful in delaying the onset of cataracts.
Cataract Home Remedies
Garlic is very helpful in cataract. Two or three cloves should be eaten raw daily. They should be chewed slowly. Garlic helps to clean the crystalline lens of the eye.
The flowers of pumpkin are valuable in cataract. The juice of these flowers should be extracted and applied externally on the eyelids twice daily. It will stop further clouding of the crystalline lens of the eye.
Aniseed is considered a useful remedy for cataract. An equal quantity of aniseed and coriander powder should be mixed with one teaspoon of brown sugar, and the mixture should be taken in doses of 12 gm in the morning and evening.
The use of unprocessed pure honey is another effective remedy for cataract. A few drops of this honey should be put in the eyes. This is an ancient Egyptian remedy, which has benefitted many patients.
Almonds are valuable in cataract. Seven kernels should be ground finely with half a gram of pepper (kali mirch) in half a cup of water, and drunk after sweetening the mixture with a teaspoon of sugar candy. It helps the eyes to regain their vigour.
Certain nutrients have also been found useful in cataract. Experiments have shown that animals develop cataract if deprived of pantothenic acid and amino acids, and tryptophane and vitamin B6 needed for tryptophane assimilation. The diet of the cataract patient should, therefore, be high in vitamins B2 and B6, as well as the entire B complex group, pantothenic acid, vitamins C, D, E and other nutrients.
The use of carrots is considered beneficial in the treatment of cataract. The patient should take plenty of raw carrots daily. As an alternative, he may drink two glasses of fresh carrot juice, one each in the morning and evening.
CALL THE DOCTOR
If you have symptoms such as progressive deterioration of vision, decreased night vision, or problems with glare.
Also call if you have a family history of congenital cataracts or if your child has symptoms or signs suggestive of a cataract
