A Beam of Light

Once destined to live in darkness, dozens of people hit by retinal diseases rediscover the light, when scientists tried to overcome blindness. "Bionic retina" allows people who are blind to be able to go back to "see" the sidewalk, or also the door for example, and even the texts.

The Bionic Retina

During this time, the development of drugs attempted to stop some form of age-related blindness. While in the laboratory, stem cells attempted to repair retinal tissue. Maria Canto-Soler, who is director of the retina in Degeneration Research Center, Johns Hopkins University, US. said that;

"Things that are considered impossible a few years ago, can now be realized, and it may not be right to say that we will find a way to cure degenerative diseases of the retina in just a few years away, but we are certainly on the right track. So it's just a matter of time."

Retinal degenerative diseases, such as retinitis pigmentosa (RP) affects more than 30 million people worldwide, according to the Foundation Fighting Blindness (FFB), which is headquartered in Columbia, Maryland.
So then, If you have late-stage retinitis pigmentosa (RP), you may be a candidate for the Argus® IIRetinal Prosthesis System (Argus II), a retinal implant that could provide partial sight for individuals with the disease.

The Bionic Eye

Sometimes referred to as an artificial retina or “bionic eye” the Argus II was approved by the Food and Drug Administration in the last February 2013. It was developed by Second Sight Medical Products, Inc. and is now offered at the University of Michigan Kellogg Eye Center, one of 13 major centers across the country to offer the implant.
Age-related Macular Degeneration (AMD) is the leading cause of blindness in people over 50 years in developing countries. Meanwhile, Usher syndrome, a major cause of combined deafness and Blindness. The scientists expect that patients who are convicted of degenerative retinal diseases will not be permanently impaired.
However, no longer just in the realm of science fiction, bionic retina has changed the lives of dozens of people who use it, both in the US and Europe. The system is constructed by planting a 'chip' in the eye, which is able to mimic the function of photoreceptor cells. It is usually combined with a miniature camera mounted on a pair of sunglasses. The camera sends images via a mini computer on a chip, which is connected to an electrical signal to the brain, to form a view. The chip itself is functioning as well as photoreceptors and transmitter. The implant recipients can create shapes and patterns of light, which allows them to avoid obstacles on the road, for example, or even read the street signs are great.

"The chip is changing everything. I can stop at the edge of the road, cross the road and find another sidewalk on the other side of the road, and If I go to a bar (pub), I know where there are people. I can not see their faces, but I know there are other people around me. So no longer sit in a dark room, without ever know if you're talking to yourself or someone on your side. It's exciting!".

Said "Mr. K", the receiver type Argus II retinal bionic prosthesis manufactured Second Sight in California, in the last 2009. And the picture above is Dr. Naheed Khan, right, works with Roger Pontz, left, on an exercise to test how well he sees shapes on a computer screen at the University of Michigan Kellogg Eye Center, in the last April 16, 2014.

Genetic Therapies

Another promising field is genetic therapy. A clinical trial at Children's Hospital of Philadelphia has managed to restore the view of 40 children and adults were nearly blind, after suffering from retinitis pigmentosa.

One that helped was Corey Haas, "He is now able to see the blackboard at school," the statement Foundation Fighting Blindness.

Genetic therapy works by injecting a corrective gene into retinal cells to replace damaged cells. A single treatment can last a few years, maybe even a lifetime.
Corey Haas received treatment in the last 2008, when he was eight years old. In a video that was recorded in September 2013 and then, he appeared running outdoors, wearing a pair of lightweight glasses, hitting a nail into a wooden block, ride a bike, and building a Lego toy.
"Four days after the operation we are going to the zoo and Corey says: 'The sun hurts my eyes' - it had never happened," his mother, tells with tears of joy.
In earlier this month, a team of researchers Canto-Soler said they have used stem cells to create human retinal tissue in the laboratory "has the ability to sense light". Transplantation of genetically modified cells according to them could cure blindness.

The Blind Person who Inspired the World

Somewhat deviated from the main discussion in this article which I also try to share information about people who have a deficiency (blind) but have a career and achievements are commendable and even imitated for everyone. And these data are quoted from various sources of data.
Blind not be a fundamental reason for not able to do something more like most normal people. Although the circumstances are not normal (blind) turns out some great people who are able to achieve the highest career and even beat normal people and they have become an inspiration to everyone. Here are some people who have a deficiency (blind) who never makes the world stunned with their expertise.

  4. Tofiri Kibuuka is an athlete who used to compete for Uganda, before finally obtain Norwegian citizenship. He often participates in the Pre olympics and then from 1976-2000, he won five silver medals and one bronze. In 1968, Tofiri be one of the first blind person who successfully reached the summit of Mount Kilimanjaro. Tofiri action makes then get media attention and praise from the Minister of Labour Uganda.

  5. Helen Keller
  6. A woman who is full name Helen Adams Keller was living as a writer, political activist, and lecturer of America. She is the first deaf successfully obtained a Bachelor of Arts in America. Physical limitations make it struggled to keep learning how to communicate well. Now his birthday which falls on June 27 is celebrated as the Day of Helen Keller in the state of Pennsylvania, USA.

  7. Andrea Bocelli
  8. A man full name is Andrea Bocelli's Angel is an Italian tenor who has worldwide. Born with poor eyesight condition, he permanently blind at the age of twelve years after an accident while playing football. Since winning the Best Newcomer category in the Sanremo Music Festival in 1994, Bocelli name increasingly skyrocketed in the world music scene. He has recorded fourteen solo studio albums, classical and pop music, the three greatest hits album, and nine operas, and sold more than 80 million records worldwide.

  9. Stevie Wonder
  10. Musicians Stevland Hardaway Morris's full name, was born May 13, 1950 with the name Stevland Hardaway Judkins. He is known by his stage name Stevie Wonder. Stevland are now known as a musician, singer and songwriter. He developed into one of the most creative musicians in the world and very fond of musical luminaries from the end of the 20th century. Shortly after birth, small Stevland suffer permanent blindness that made him unable to see.

  11. Marla Runyan

Those are the six blind person who managed to conquer the world and inspiring for everyone, especially for people who have physical / body perfect.

Conclusions and the Data Credits*

What Are The Causes Of Blindness? There are many causes of blindness. Sometimes blindness can be cured or vision improved with medicines, surgery, and special equipment. Or blindness is the condition of poor visual perception, it means that the various scales have been developed to describe the extent of vision loss and define blindness.
Below is a list of different causes of blindness.

  1. Accidents
  2. One basic cause of blindness can be accidents that injure the eye. Sometimes the eye can be saved and sometimes not with medicines, surgery, etc.. It is very important to do the following to preserve good eyesight:

    • Do not throw objects in people's faces or at their heads.
    • Be very careful when using sharp objects such as scissors and knives and point them away from your face.
    • Wear goggles or protective glasses when asked to such as when working with chemicals, etc..

  3. Cataracts
  4. Cataracts are formed in the lens of the eye which is behind the black dot (pupil) in the middle of the eye. As people get older, the lens of the eye gets cloudy. When people have cataracts it is as if they are looking through a fog. As the cataracts get worse, the fog gets thicker. Although older people more often get cataracts, sometimes kids can have them as well. Your grandparents may get cataracts.
    Cataracts can be removed by taking out the lens of the eye with surgery and having an artificial lens put in. People can have their vision return to normal after this surgery.

  5. Macular Degeneration
  6. This disease is one of the leading causes of blindness among older people and can't be cured as of yet. With this disease, the middle of the back of the eye called the macula is diseased.
    To understand what a person with macular degeneration sees, make your hands into fists and put your fists right up in front of each eye. Notice that you can see around the fists, but not directly in front of you. People with macular degeneration cannot read or recognize people, but can sometimes move around without as much assistance because the center of the back of the eye is in charge of a person seeing small details that lets them read and recognize people.
