Lutein is helpful to your vision

As the age increasing, our sights are inevitably getting worse. Normally, when people are 50 years old, some people may be a little younger, people’s vision begin to deteriorate. But now we find that lutein enriched multi-vitamins are helpful to defer people’s vision deterioration.

The aged-related macular degeneration or AMD for short is the main condition in this piece. AMD make a vision loss in the central retina. The reasons cause AMD are complex, but some reasons can be certain that eyes expose in the UV light for long time can make this problem. And a change in the concentration of the macular pigment that compound lutein and zeaxanthin are also believed to make AMD happen.

We can not stop getting old so that our sights are inevitably getting worse, but we can take some measures to delay or minimize the onset of AMD, some tips are as follows: try to manage your blood and avoid getting hypertension; control the cholesterol in a low level; avoid over weighted; do not have too much fat; and do not smoke. The smokers get the risk of AMD higher by two or three times than the normal people.

What is the most important, the more you intake of lutein, the less risk you take AMD, because its cousin compound zeaxanthin will help mitigate AMD. Enough macular pigment compounds are important in eyes health. People can get lutein from the foods such as Brussels sprouts, swiss chard, garden peas, corn, zucchini, broccoli, romaine lettuce, collard greens, turnip greens and kale.

When people get intake some kind of lutein enriched food that whether they get the proper amount of the nutrients is unknown, because it is a big molecule and it dissolves in organic solvents. So if people want to get recommended amount of lutein, they had better drink some kind of oil to help the lutein to get absorbed.

Another way to get proper lutein is to get lutein enriched multi-vitamins. People can easily get the quantity of the recommended nutrient. What is more, some good ones also comes with zeaxanthin which can make lutein have greater effectiveness. Also, they are more convenient.

Some good multi-vitamins also contain some other ingredients; some kind of ones may have about 100 ingredients. Also, accord to different requirements they can be made in different types. For instance, they can be tailored to respectively suit men and women. And good multi-vitamins also include some other good things.

What you should know about Diabetic Retinopathy

It’s estimated that 40 to 45 percent of Americans diagnosed with diabetes have some stage of Diabetic Retinopathy.  Diabetic Retinopathy is caused by damage to the retina.  It is the leading cause of blindness in adults in the US.  With Diabetic Retinopathy, blood vessels may leak or new blood vessels can grow on the surface of the retina, which may result in patches of blind spots. 

 

In the early stages of the disease, there are often no symptoms or pain. However, as the disease progresses, individuals can experience blurred vision, specks of blood or spots in their vision, vision loss, and even blindness. 

There are four stages of Diabetic Retinopathy, they are: 

  1.  Mild Nonproliferative Retinopathy:  This is the early stage of the disease.  In this stage, swelling occurs in the retina’s blood vessels
  2. Moderate Nonproliferative Retinopathy:  In this stage, some blood vessels that supply the retina become blocked. 
  3. Severe Nonproliferative Retinopathy:  In this stage, more blood vessels supplying the retina become blocked and the eye then starts to grow new blood vessels. 
  4.  Proliferative Retinopathy:  This is the advanced stage of the disease.  The new blood vessels have thin walls and grow along the retina and the gel that fills the inside of the eye.  If these blood vessels break, it can result in vision loss and even blindness. 

Populations at Risk for Diabetic Retinopathy 

  • People with Type I diabetes
  • People with  Type II diabetes
  • Some pregnant women with diabetes

Controlling blood sugar, blood, pressure, and cholesterol are key in preventing progression of the disease.  In the latter stages of diabetic retinopathy, someone may undergo laser surgery and a virectomy (removal of the blood from the center of the eye).  Check out the National Eye Institute to learn more about treatment for Diabetic Retinopathy.

The debate on Lucentis and Avastin

For those 200,000 AMD patients within an average year in US, the most effective treatment that approved by FDA is Lucentis. It brings hope to wet AMD patients by stopping and sometimes reversing vision loss, which is a huge breakthrough. Yet another drug that is similar to Lucentis is also under wide discussion, which is named Avastin. But Avastin is much cheaper than Lucentis, so that many doctors recommend Avastin for low-income individuals.

However, Avastin has not received FDA approval for ophthalmic uses. Based on safety issues, Genentech also restricts the sale of Avastin to compounding pharmacies for ocular uses. Both Lucentis and Avastin are owned by this company. Since the FDA has expressed no concern about the Avastin’s off label uses for AMD, many eye doctors argue that Genentech should allow Avastin to be directly sold to both physicians and compounding pharmacies. If only physicians have access to Avastin, doctors at the American Academy of Ophthalmology protest that many lower income people will be deprived of this sight-saving drug. The fact is that Lucentis cost an average of $2,000, while Avastin only needs $150.

During the widely off-label uses of Avastin, this treatment has not been proved to be as effective as Lucentis, or even more effective. No clinical study has made a comparison between the two AMD treatments. The most concern is their price discrepancy. Even if Medicare and other health insurance plans offset parts of the Lucentis expense, it is still much more expensive than Avastin. For example, patients with Medicare may only need to pay a 20% of co-payment for Lucentis, which equals about $400.

Genentech has given explanations about its different policies of the two drugs. Genentech officials say that the high price of Lucentis comes from its special development and its considerable expense of clinical trials. Lucentis is administered in the form of smaller molecules, which are more effective in controlling abnormal blood vessels. The company also claims that they will not conduct new trials for Avastin, since Lucentis has already got FDA approval and is a promising AMD solution. The good news may be that the US government is likely to fund the comparison between Lucentis and Avastin.

While the initial use of Avastin for colon and other cancers was reported to arouse risks of stroke and heart attack, its use for macular degeneration has brought no negative side effects. Most of the doctors are positive about the Avastin’s long-term safety risks. Due to its low price, researchers encourage the use of Avastin. There are also concerns that Avastin may be unable to penetrate the eye’s retina effectively. The undergoing two-year NEI clinical trails may settle down all these controversies.

An introduction of contact lenses prescription

Currently, Americans in all 50 states can buy contacts both from ECPs and other sources such as optical chains, warehouse clubs and online stores. This privilege originates from a 2004 legislation that patients are entitled to obtain a copy of contacts prescription from ECPs without extra cost, which was only available in certain states before that time. This law profoundly separated fitting and lenses buying. You will never be forced to buy contacts from ECPs after been fitted. Today, contacts prescriptions are just like ones of other medical products like medicines that may provide more information than eyeglasses prescriptions. With a prescription, customers can buy disposable lenses regularly.

An accurate prescription is needed for contacts. Poorly fitting contacts and lenses made of unsuitable materials may cause discomfort, inflammation, swelling, and most severely, permanent vision loss. Sharing contacts may also bring dangerous infections. In US, optometrists, ophthalmologists as well as opticians are entitled to fit contact lenses.

Subtle eye problems may have developed even you are still feeling good with your eyes and contacts. Some ophthalmologists have ever found eye problems during regular eye exams, so that you must update the prescription within a certain period, which is also listed by either federal law or state law. Another point worth mentioning is that you can change your contacts size, material or design if you are diagnosed with a lens-related problem.

Contacts prescriptions use standard terms, abbreviations and measurements, which look like secret codes yet easy for recognition. Besides regular items, your prescription may also tell the recommended replacement period or the expiry. By US law, the expiry normally is at least one year and in most of the cases it may be longer than this. However, you should always follow your ECP for final decision, rather than the products instructions.
