#Oral med wakes up retinal cells so kids can see Tests of a new oral medication show the drug can improve vision in children with an inherited disease that can cause complete blindness
and is currently untreatable. his is the first time that an oral drug has improved the visual function of blind patients with LCA (Leber congenital amaurosis),
Their blindness was caused by either mutations in the genes RPE65 or LRAT, leading to a serious defect in the retinoid cycle.
which was funded by QLT Inc, the Foundation Fighting Blindness Canada, the Canadian Institutes of Health Research, the Fonds de recherche du Québec-Santé,
The sensor would be embedded with an artificial lens during cataract surgery and would detect pressure changes instantaneously,
If you can fit this sensor device into an intraocular lens implant during cataract surgery it won require any further surgery for patients.

Shen says. e want every surgeon who does cataract surgeries to be able to use this.
The team has tested successfully the sensing device embedded in the same flexible silicon material that used to create artificial lenses in cataract surgeries.
and ultimately blindness. ftentimes damage to vision is noticed late in the game, and we can treat patients effectively
Both cataracts and glaucoma affect a similar aging population so it seems a natural pairing to place a pressure monitoring device in a new lens during cataract surgery.
MAKING IT COST-EFFECTIVE The team is working on downscaling the prototype to be tested in an actual artificial lens.
#DNA sequencing reveals six new forms of blindness Scientists have discovered six new forms of inherited blindness,
which multiple members were blind from birth due to conditions such as Leber congenital amaurosis, cone-rod dystrophy,
Inglehearn says. ince new therapies are often specific to particular forms of inherited blindness, it is essential for each patient to know which condition they have,
One common problem for example is presbyopia a type of farsightedness in which the ability to focus on nearby objects is diminished gradually as the aging eyes lenses lose elasticity.
which was developed at UC Berkeley works by adjusting the intensity of each direction of light that emanates from a single pixel in an image based upon a user s specific visual impairment.
causing a wide range of problems that include extreme fatigue, dementia, stunted growth, deafness, blindness, multi-organ failure, and even death.
#3d printed eye cells could one day cure blindness Researchers have printed actually viable retina cells using an inkjet printer.
Living, 3d printed retina cells could someday aid in curing many#kinds of blindness.####At the University of Cambridge, researchers have pulled off something of a 3d printing coup.
Developers had to overcome unusual challenges to help people with visual impairments move their reading fingers along a straight line of printed text that they could not see.
in a clinical study set to start this year on the eye condition known as macular degeneration. Other ministries have jumped also on the ips-cell bandwagon.
these are showing early evidence that a product made from human ES cells can help to rebuild the layer of cells that support photoreceptors in the eyes of people with certain types of blindness.
System gives hope to those blinded by a rare genetic eye condition called advanced retinitis pigmentosa, which damages the light-sensitive cells that line the retina.
#Eye drops could dissolve cataracts Cataracts cloud the eyes of tens of millions of people around the world and nearly 17.2%of Americans over the age of 40.
or scalpels cut away the molecular grout that builds in the eye as cataracts develop, and surgeons sometimes replace the lens.
But now, a team of scientists and ophthalmologists has tested a solution in dogs that may be able to dissolve the cataract right out of the eye lens.
Though scientists don fully understand how cataracts form, they do know that the ogoften seen by patients is a glob of broken proteins,
causing the signature teamy glassvision that accompanies cataracts. Coming up with a solution other than surgery has been tough.
Her team came up with the eye drop idea after finding that children with a genetically inherited form of cataracts shared a mutation that stopped the production of lanosterol, an important steroid in the body.
the adults produced lanosterol and had no cataracts. So the researchers wondered: What if lanosterol helped prevent
or reduce cataracts? The team tested a lanosterol-laden solution in three separate experiments. First, they used human lens cells to test how effectively lanosterol shrank lab models of cataracts.
They saw a significant decrease. Then, they progressed to rabbits suffering from cataracts. At the end of the 6-day experiment, 11 of 13 rabbits had gone from having severe or significant cataracts to mild cataracts or no cataracts at all.
Finally, the team moved on to dogs, using a group of seven, including black Labs, Queensland Heelers,
and Miniature pinschers with naturally occurring cataracts. The dogs responded just as the researchers hoped to the lanosterol solution,
which was given in the form of both eye injections and eye drops. The dogslenses showed the same type of dissolving pattern as the human and rabbit lens cells.
The improvement was remarkableesearchers could tell just by looking at the dogseyes that the cataracts had decreased.
He has been investigating cataract proteins since 2000. hey discovered the phenomena and then followed with all of the experiments that you should dohat as biologically relevant as you can get. uben Abagyan,
In people with a disease called retinitis pigmentosa, cones slowly atrophy, eventually causing blindness. Friedrich Miescher Institute scientists Botond Roska and Volker Busskamp have shown previously that some vision can be restored in mice by engineering those cone cells to express light-sensitive proteins.
which can cause blindness. ndothelial cells play a very important role in multiple steps of many diseases, from initiation to the onset of clinical complications,
According to TAU doctoral student and research team member Dr. Lilach Bareket there are already medical devices that attempt to treat visual impairment by sending sensory signals to the brain.
ARMD is in fact the greatest cause of blindness in people over the age of 50
which could improve vision in older people with presbyopia and cataracts. As people age, their lenses lose flexibility and elasticity.
This leads to a condition known as presbyopia, common in people over 45 years old, and can require optical aids, such as reading glasses.
The lens could also have application in tackling cataracts-the clouding of natural lenses -which affect many people in later life and
Their eyes have caused defects largely by refractive errors, cataract, or glaucoma. They don see the world as the rest of the seeing world does and, due to the high costs of healthcare or unavailability of medical facilities,

which can be a complication of cataract surgery. The company envisions a wide application of this immunodepletion strategy in other fibrotic diseases and cancer,

#Ubisoft offers new video game it says can treat lazy eye The Montreal-based gaming company Ubisoft has developed a video game it says could be used to treat amblyopia, also known as lazy eye.

The company says it's the first video game based on a patented method for the treatment of amblyopia.

The examining optometrist was kept unaware of the initial JVAS vision screening results. No children who already wore glasses,
had been treated for amblyopia, or had undergone ocular surgery were included in the screening. The average screening time was 84 seconds, with a range of 23 to 357 seconds across all age groups.
Of the 65 children failing the gold standard examination, 86%failed for reduced visual acuity (56), 35%for hyperopia (23), 23%for astigmatism (15), 11%for anisometropia (7), 9%for myopia (6),
