Diabetic Eye Disease Overview

Diabetes mellitus is one of the leading causes of irreversible blindness worldwide, and, in the United States, it is the most common cause of blindness in people younger than 65 years of age.

In addition to being a leading cause of blindness, diabetic eye disease encompasses a wide range of problems that can affect the eyes.

Diabetes mellitus may cause a reversible, temporary blurring of the vision, or it can cause a severe, permanent loss of vision.

Diabetes mellitus increases the risk of developing cataracts and glaucoma.

Some people may not even realize they have had diabetes mellitus for several years until they begin to experience problems with their eyes or vision. Severe diabetic eye disease most commonly develops in people who have had diabetes mellitus for many years and who have had little or poor control of their blood sugars over that period of time.

Diabetes mellitus may also result in heart disease, stroke, kidney failure, and circulatory abnormalities of the legs.

The American Diabetes Association estimates that 20 million people in the United States have diabetes. One-third of this population is unaware of their illness. A recent change in the exact definitions of diabetes and "pre-diabetes" by an international expert committee leads to the estimate that an additional 41 million people in the United States (40% of adults aged 40-74 years) have "pre-diabetes," a condition that significantly increases their risk for developing diabetes.
This new definition underscores the importance for everyone to take steps to help prevent the development of this disease. Individuals can try to avoid the problems associated with diabetes mellitus, including those that affect the eyes, by taking appropriate care of themselves by:

Maintain a normal weight

Watch your diet, especially limiting unhealthy types of fats and substituting complex carbohydrates for simple carbohydrates.

Participate in an exercise program, performing at least 2 1/2 hours of aerobic exercise very week.

Do not smoke

Lifestyle management has been shown to reduce the risk of developing type II diabetes and pre-diabetes by at least two-thirds. It can also slow or halt the progression of pre-diabetes to diabetes.

If you or someone you know has already been diagnosed with diabetes mellitus, the following steps should also be taken:

Monitor blood sugars and glycosylated hemoglobin. (The protein in the red blood cells that carry oxygen is called hemoglobin. Glycosylated hemoglobin is hemoglobin that has bonded to blood sugar.)

Take diabetes medications as prescribed by the healthcare provider.

Things You Should Know About Eye Diseases

Lucky for us there are many trained professionals who specialize in this particular area as there are so many eye diseases.

Sometimes these problems relating to eye occur due to eye strain or a person not taking proper care of his or her eye sight the way it is meant to be taken care of and there are even certain individuals who are genetically predisposed. Some of these eye diseases are curable while some are not as some can be stopped from advancing and some can even be totally reversed. If you are having any sort of problem relating to eye then the first thing you need to do is get you eyes examined and determine what sort if condition your eyes have and once you have determined that then you can take care of it accordingly.

There are five eye diseases which are most common in effecting the eyes. The first one on them is known as Hyperopia which is more commonly termed as far sightedness. It is the kind of eye problem where the distant vision is clear but the eyes are unable to focus on close work. The major symptom of far sightedness is blurred vision when performing or dealing with close works like reading. Other symptoms of this eye disease include headache and eye strain. The eyeball in this case becomes shorter than it normally should be and therefore a deformation of the eye muscle takes place.


The second one of these major eye diseases is Myopia which is more commonly known as near sightedness. In this case the person is unable to see distant objects clearly and as a result different other problems arises because distortion of the eye ball takes place due to near sightedness and is exactly opposite to that of Hyperopia as the eyeballs lengthen more than they normally should. Cataract is the third one among these eye diseases and is usually considered to be related to aging as the eye becomes weaker with age and as a result naturally occurring proteins join together and make clumps which increase in size over time and begin to grow over the lens thus making the vision blurry.

Astigmatism is the fourth eye disease in which the cornea of a person ceases to be round in shape and becomes curved and as a result the vision is affected and it needs to be diagnosed by a specialist in order to be treated in the right manner. Glaucoma is the fifth one and is one of the most common eye diseases where a person loses peripheral vision due to damage of the optic nerves and it is also the main symptom of it. It is caused by the build up of fluid in the eye. It has the tendency to come on slowly thus a person does not realize that his vision is changing. So in order to protect ourselves from this disease one needs to get his eyes examined every two to three years so that it can be diagnosed even before symptoms of it occur.

Walmart tries new tech with eye on consumers

Walmart could start letting shoppers buy products in the aisles and skip the checkout line, but the world's largest retailer needs to find out how that would improve the customer experience, the company's e-commerce chief said Thursday.

With Apple's new EasyPay feature for its Apple Store iOS app, shoppers with an iPhone 4 or 4S can buy some products simply by scanning the barcode, entering their Apple ID, and walking out with the item. Venky Harinarayan, Walmart's senior vice president of global e-commerce and head of Walmart Labs, said the issue with setting up such a feature is not technology but the user experience.

"Yes, you can do this. ... What we've got to figure out is, how do you make that customer experience something really worthwhile," Harinarayan said. The same is true of other new technologies. "These are not technology problems, they are customer experience problems."

Walmart is also interested in NFC (near-field communication) for making purchases by phone and in setting up a social network among the shoppers in its stores. But the company has just begun to study how those could make Walmart a better place to shop, Harinarayan said. He appeared in an on-stage interview at the GigaOm Roadmap conference in San Francisco. Walmart Labs was established earlier this year in Mountain View, California, following the retailer's acquisition of Harinarayan's startup Kosmix, to try out these types of ideas, he said.

Walmart has high hopes for a blending of social media and shopping, Harinarayan said. At the corporate level, the company could use trend information from social-networking sites such as Facebook and Twitter to inform its product and distribution decisions. Walmart Labs is setting up a "big and fast data group" to explore ways to take advantage of the huge amounts of information it has about shopping behavior and combine it with social-networking data, he said.

For example, finding out when people in Wisconsin start mentioning college football in status updates could help the company decide when to start putting team merchandise on shelves in that state, he said. And decisions about what toys to sell during the year-end holiday season, which need to be made in February or March, prove more accurate if the company looked at what types of toys people were talking about at that time, he added.

Within brick-and-mortar stores, Walmart may eventually set up a mobile social-networking service of its own, where shoppers and sales associates all could post comments and questions that everyone in that store could see, Harinarayan said. "How will this work? We don't know. But it's a very interesting experiment for us," he said.

Walmart's online store could tap into social networking even more deeply, Harinarayan said. The company is trying to find the right way to take advantage of data on daily activity on online social services. That won't be simply by having a Facebook page where users can find and buy things, but through integrating shopping into the usual things Facebook users do, he said. An obvious way is with buying gifts, a naturally social activity. "Gifting is not done well today on the Web," Harinarayan said.

"This actually has been playing really, really well over the last few weeks as we've started engaging some of this," he said. Mining social-networking data "can impact billions of dollars of merchandise if we get it right," he added.

Walmart eventually would like to provide an API (application programming interface) and let third parties create applications using some of these capabilities, but it is still very early in the development process, Harinarayan said.

Harinarayan declined to give more details on Thursday about Walmart Labs' purchase of Australian startup Grabble, a developer of point-of-sale systems for mobile phones.

Eye Disease- Stye Problem

Eyes are organs that detect light, and send electrical impulses along the optic nerve to the visual and other areas of the brain. Some eye problems are minor and fleeting. But some lead to a permanent loss of vision. Common eye problems include:
Cataracts - clouded lenses
Glaucoma - damage to the optic nerve from too much pressure in the eye
Retinal disorders - problems with the nerve layer at the back of the eye
Conjunctivitis - an infection also known as pinkeye
Stye- A stye, or hordeolum, is a small bump that can appear on the outside or inside of the eyelid.

A sty is an acute infection or inflammation of the secreting glands of the eyelid. A sty can also arise from an infected hair follicle at the base of an eyelash. It is sometimes referred to as a pigpen or pig parlor. Sties are usually areas of bare ground and / or mud. It is caused by bacteria that normally live peacefully on the surface of the eyelid skin. It is a red, painful swelling on the edge or inside of your eyelid that may look like a boil or a pimple. Also known as hordeolums, styes can be caused by different factors, such as blocked or infection or inflammation of the eyelid eyelids. Contaminated fingers that touch the eye area can also cause infection. The eyelid becomes sore. The infection can spread along the eyelid and the whole lid may become red and inflamed. If an internal Sty not drain and heal, it can turn into a Chalazion. A sty results from an acute infection of the oil glands of the eyelid that occurs after these glands have become clogged.

Causes of stable
Common causes and risk factors:
a) An infection in the sebaceous (oil producing) or sweat glands in the eyelid.
b) A Chalazion develops when an oil gland in the eyelid becomes blocked.
c) Using mascara, eyeliner, eye or other products that can irritate the eyes.
d) Rubbing eyes.
e) Symptoms stable

Here is a list of methods of treatment:
a) Most styes will drain on its own though this may be accelerated with a hot or warm compress.
b) Use makeup remover instead of just soap and water to remove eye make-up. This prevents heavy rubbing of your eyes and more completely removes the make-up.
c) Although antibiotics are often used to treat styes, they do not help much.
d) If a style or Chalazion is too large, the doctor may need to bid so that can drain and heal.
e) Paracetamol will also help relieve the pain of a sty.
f) A sty does not begin to improve after 3 days of home treatment or does not heal in a week.
g) Antibiotic ointments or eye drops may help cure the infection. If the skin around it is becoming infected, antibiotic pills may be needed.

Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss.
