Symptoms, Causes and Home Remedies for Cataract or Glaucoma Treatment

Cataracts refer changes in visibility of the natural lens inside the eye that slowly affects visual quality. This vision disease may come with different symptoms depending on a variety of factors such as age, injury, and diseases. Usually, people at 60s or 70s suffer this disease while some people have cataracts at birth. Dim, blurry, cloudy, and foggy vision are some impacts of a cataract. Cataract symptoms occur gradually and painlessly, so many people do not realize that they have these symptoms.

In fact, the development of cataract is extremely slow but sometimes it goes faster. Cataracts normally affect the visual quality of both eyes, but in some rare cases cataracts may be found in one eye only. Cataracts are regarded as a very popular visual disease and many cataract surgeries are conducted all over the world every year.

It is very important to understand the cataract symptoms. When people suffer cataracts, they start to have difficulties in doing their daily activities. The difficulties include problems when they are driving at night, reading, participating in sports such as golf, and traveling to unfamiliar areas.

A doctor says you suffer cataracts when you are experiencing symptoms like cloudy or foggy vision, blurry or distorted vision, changes in color vision, frequent increases in eyeglass or contact lens prescriptions, poor night vision (especially affected by headlights), progressive loss of vision, halos or glare around lights, double vision, loss of contrast, a white or "milky" spot over the pupil of the eye, cloudy vision, deteriorating vision, and trouble with night vision.

Cataract Symptoms:

Symptoms include blurry vision that is made worse when subjected to bright light (i.e. sunlight or bright headlights when driving). Light may seem to scatter or there may be halos (rings) around light sources.

Others will describe their symptoms as cloudy, fuzzy or foggy vision. Both eyes will typically be affected; however, it is not unusual for one eye to be worse than the other. Symptoms of cataracts tend to develop gradually but overall vision will continue to deteriorate if not treated and can lead to blindness.

Cataracts often occur with aging and are more common over 60 years of age. Risk increases with a family history of cataracts, hardening of arteries, diabetes mellitus, long term use of cortisone drugs, smoking, or exposure to radiation. Cataracts can be present in infants (congenital cataracts).

Cataract Causes:

The lens is made mostly of water and protein. Specific proteins within the lens are responsible for maintaining its clarity. Over many years, the structures of these lens proteins are altered, ultimately leading to a gradual clouding of the lens. Rarely, cataracts can present at birth or in early childhood as a result of hereditary enzyme defects, and severe trauma to the eye, eye surgery, or intraocular inflammation can also cause cataracts to occur earlier in life.

Other factors that may lead to development of cataracts at an earlier age include excessive ultraviolet-light exposure, diabetes, smoking, or the use of certain medications, such as oral, topical, or inhaled steroids. Other medications that are more weakly associated with cataracts include the long-term use of statins and phenothiazines.

Home Remedies For Cataract:

Carrots are said to be great part as cataract home remedy treatment. Eat plenty of raw carrots on a daily basis. If one does not like eating raw carrots then fresh carrot juice will also serve the purpose. Drink it twice a day; in the morning and in the evening.

The best home remedy for cataract also includes consuming 2-3 cloves of garlic everyday. Eat garlic raw and chew them slowly. Garlic aids in cleansing the crystalline lens of the eye but one should be cautious taking garlic if having acidity problem.

Simple home remedy for cataract includes taking extract the juice of pumpkin flowers and then applying them on the eyelids twice a day.

Using carrots has also been found as useful home remedies for cataract. A person suffering from cataract is to eat plenty of raw carrots daily. Alternatively, he or she should take two glasses of carrot juice everyday, one glass each in the morning and evening.

Some of the health experts suggest is to put a few drops of unprocessed pure honey in the eyes once or twice a day for at least 3 months. This has beneficial results in treating cataract. This is one of the effective cataract treatments.

Symptoms and Natural Treatment for Cataract or Glaucoma

Cataracts are changes in clarity of the natural lens inside the eye that gradually degrade visual quality. The natural lens sits behind the colored part of the eye (iris) in the area of the pupil, and cannot be directly seen with the naked eye unless it becomes extremely cloudy. The lens plays a crucial role in focusing unimpeded light on the retina at the back of the eye. The retina transforms light to a neurologic signal that the brain interprets as vision. Significant cataracts block and distort light passing through the lens, causing visual symptoms and complaints.

The term cataract is derived from the Greek word cataractos, which describes rapidly running water. When water is turbulent, it is transformed from a clear medium to white and cloudy. Keen Greek observers noticed similar-appearing changes in the eye and attributed visual loss from "cataracts" as an accumulation of this turbulent fluid, having no knowledge of the anatomy of the eye or the status or importance of the lens.

Cataract development is usually a very gradual process of normal aging but can occasionally occur rapidly. Many people are in fact unaware that they have cataracts because the changes in their vision have been so gradual. Cataracts commonly affect both eyes, but it is not uncommon for cataracts in one eye to advance more rapidly. Cataracts are very common, affecting roughly 60% of people over the age of 60, and over 1.5 million cataract surgeries are performed in the United States each year.

Cataract Symptoms

Having cataracts is often compared to looking through a foggy windshield of a car or through the dirty lens of a camera. Cataracts may cause a variety of complaints and visual changes, including blurred vision, difficulty with glare (often with bright sun or automobile headlights while driving at night), dulled color vision, increased nearsightedness accompanied by frequent changes in eyeglass prescription, and occasionally double vision in one eye.

Some people notice a phenomenon called "second sight" in which one's reading vision improves as a result of their increased nearsightedness from swelling of the cataract. A change in glasses may help initially once vision begins to change from cataracts; however, as cataracts continue to progress and opacify, vision becomes cloudy and stronger glasses or contact lenses will no longer improve sight.

Cataracts are usually gradual and usually not painful or associated with any eye redness or other symptoms unless they become extremely advanced. Rapid and/or painful changes in vision are suspicious for other eye diseases and should be evaluated by an eye-care professional.

Cataract Treatment

The standard cataract surgical procedure is typically performed in either a hospital or in an ambulatory surgery center. The most common form of cataract surgery today is a process called phacoemulsification. With the use of an operating microscope, your surgeon will make a very small incision in the surface of the eye in or near the cornea. A thin ultrasound probe is inserted into the eye that uses ultrasonic vibrations to dissolve (phacoemulsify) the clouded lens. These tiny fragmented pieces are then suctioned out through the same ultrasound probe. Once the cataract is removed, an artificial lens is placed into the same thin capsular bag that the cataract occupied. This intraocular lens is essential to help your eye focus after surgery.

There are three basic techniques for cataract surgery:

Phacoemulsification: This is the most common form of cataract removal as explained above. In this most modern method, cataract surgery can usually be performed in less than 30 minutes and usually requires only minimal sedation and numbing drops, no stitches to close the wound, and no eye patch after surgery.

Extracapsular cataract surgery: This procedure is used mainly for very advanced cataracts where the lens is too dense to dissolve into fragments (phacoemulsify) or in facilities that do not have phacoemulsification technology. This technique requires a larger incision so that the cataract can be removed in one piece without being fragmented inside the eye. An artificial lens is placed in the same capsular bag as with the phacoemulsification technique. This surgical technique requires a various number of sutures to close the larger wound, and visual recovery is often slower. Extracapsular cataract extraction usually requires an injection of numbing medication around the eye and an eye patch after surgery.

Intracapsular cataract surgery: This surgical technique requires an even larger wound than extracapsular surgery, and the surgeon removes the entire lens and the surrounding capsule together. This technique requires the intraocular lens to be placed in a different location, in front of the iris. This method is rarely used today but can be still be useful in cases of significant trauma.
