Doctors restore patient’s sight with stem cells, offering new hope for cure to blindness

Researchers safely and effectively implanted a specially engineered patch of retinal pigment epithelium cells derived from stem cells to treat people with sudden severe AMD.

How blind people dream — the experience is just as rich, science says

Most blind people can’t see in their dreams, but their experience is just as rich as everyone else’s.

Half the world will need glasses by 2050

Nearly half the world’s population, close to some 5 billion people, will develop myopia by 2050 according to a study recently published in the journal Ophthalmology. The paper also estimates that one-fifth of these people will have a significantly increased risk of becoming permanently blind from the condition if recent trends continue.

Blind pensioner can see again following bionic eye implant

An 80-year-old man suffering from age-related macular degeneration (AMD) – the most common cause of sight loss in the world – can now see again after being fitted with a bionic eye. The technology was developed at the Manchester Royal Eye Hospital, and the implant marks the first trial for the Argus II system for AMD.

Star Trek walking cane lends virtual touch to the blind

The walking cane has helped the blind navigate obstacles for thousands of years, and its design has remained largely unchanged since – a sophisticated stick. What looks like a combination between a TV remote and a Star Trek tricorder, the Enactive Torch aims to help all the aging baby boomers, injured veterans, diabetics and white-cane-wielding pedestrians navigate their surroundings using 21st century tech.

This is not SciFi: software update slated for bionic eye will grant higher resolution and colour vision

The Argus II is the first bionic eye implant, designed to grant the blind vision, that has been approved by the FDA in the US. The wearer of such an implant is now capable of distinguishing objects and live an almost independent life, which is absolutely remarkable by itself, however its performance is light years away from the natural counterpart.

Virtual game for the blind help them navigate their surroundings

It’s rather difficult to imagine a video game for the blind, seeing they can’t actually see, but what people should loose sight of is that the other four senses are still there, and they’re quite sharper. A group of researchers at the  Department of Ophthalmology at Massachusetts Eye and Ear Infirmary and Harvard Medical School have developed a game whose environment

Retina implant restores sight to the blind

In the culmination of 15 years worth of painstaking research work related to retina implants, scientists from Germany and Hungary have for the first time demonstrated that a light sensitive electronic chip, implanted under the retina, can restore useful vision in patients blind from hereditary retinal degeneration. As part of the research, nine persons previously completely blind have had their vision

Chemical lets blind mice see instantly – no surgery, chips or genetic alteration

Remarkably, researchers University of California, Berkeley  have discovered that a chemical called AAQ can temporarily restore the vision in blind mice. The find might help people suffering from inherited genetic blindness or age-related macular degeneration, and bring back light into their world. The process isn’t quite as easy as applying eye drops, but it’s a whole lot less intrusive than surgery, bio-chips or optogenics,

Sensing technology destined for robots adapted to help the blind navigate

One of the most sophisticated parts of a robot is its navigation system, why requires precise sensing and processing of the information, if an anthropomorphic robot is to walk around a house safely or a rover trek through the rocky wastelands of Mars, for instance. Billions have been dedicated to this field, and naturally technological advances derived from research has

Algae gene therapy could cure blindness

Researchers have managed to restore light perception to mice through gene therapy, by inserting algae genes into the retina. The treatment has succeeded in restoring the ability to sense light and dark to blind mice, and clinical trials in humans could begin in as little as two years. “The idea is to develop a treatment for blindness,” says Alan Horsager,
