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.
Retinitis pigmentosa#which affects about one in 4, 000 people in the US and about 1. 5 million people worldwide#kills the retina s photoreceptors,
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.
making it potentially more useful for treating retinitis pigmentosa. This type of noninvasive approach to optogenetics could also represent a step toward developing optogenetic treatments for diseases such as epilepsy,
Loss of rods and cones is the primary cause of vision loss in diseases such as macular degeneration or retinitis pigmentosa.
We believe our results could eventually have a substantial impact on the development of treatments for retinal degenerative diseases like retinitis pigmentosa
manufactured by the US firm Second sight, has previously been used to restore some vision to patients who are blind as a result of a rare condition known as retinitis pigmentosa.
and his brain now needs to get use to interpreting it. he Argus II retinal implant was used previously on 130 patients with the rare eye disease retinitis pigmentosa.
the implant received market approval from the Food and Drug Administration (FDA) in the US, for the treatment of Retinitis Pigmentosa (RP) a degenerative condition that affects the peripheries of patient vision.
and his colleagues could one day be used to culture tissue that can be transplanted into a human retina damaged by conditions such as macular degeneration and retinitis pigmentosa,
it also reliably restores vision in those who suffer from the degenerative eye disease retinitis pigmentosa.
"This study shows that the Argus II system is a viable treatment option for people profoundly blind due to retinitis pigmentosa,
They worked with 30 patients aged between 28 and 77 who had little or no light perception in both eyes as a result of retinitis pigmentosa.
#Gene tied to profound vision loss discovered by scientists An exhaustive hereditary analysis of a large Louisiana family with vision issues has uncovered a new gene tied to an incurable eye disorder called retinitis pigmentosa,
Retinitis pigmentosa damages this film (the retina) and its early symptoms include decreased night vision and peripheral vision.
and his colleagues report their discovery of a new gene tied to retinitis pigmentosa, which brings the total of genes associated with this sight-threatening disease to more than 60.
"For approximately three decades, Daiger, a member of the Human genetics Center at the UTHEALTH School of Public health, has been following the progress of hundreds of families across the country with retinitis pigmentosa."
There are different types of retinitis pigmentosa and Daiger's laboratory is focused on the autosomal dominant type.
and quality of life for people blinded by retinitis pigmentosa. They are being published online in Ophthalmology, the journal of the American Academy of Ophthalmology.
Retinitis pigmentosa is an incurable disease that affects about 1 in 4 000 Americans and causes slow vision loss that eventually leads to blindness.
Through the device, patients with retinitis pigmentosa are able to see patterns of light that the brain learns to interpret as an image.
"This study shows that the Argus II system is a viable treatment option for people profoundly blind due to retinitis pigmentosa--one that can make a meaningful difference in their lives
such as retinitis pigmentosa and age-related macular degeneration. f we can maintain the vision our patients have,
California-based Second sight and previously implanted into to patients with advanced retinitis pigmentosa, converts video images from a miniature camera installed in Flynn glasses.
