Retinal Degeneration News and Research

RSS

Retinal tissue may degenerate for a number of reasons. Among them are: artery or vein occlusion, diabetic retinopathy, R.L.F./R.O.P. or disease (usually hereditary). Retinitis pigmentosa, retinoschisis, lattic degeneration, and macular degeneration are characterized by progressive types of retinal degeneration.

Researchers engineer cells in the eye to be light sensitive that were not before

In an experiment that could offer a new pathway to restoring vision in people with inherited retinal degeneration, researchers have engineered cells in the eye to be light sensitive that were not before.

Fish oil may help protect against age-related macular degeneration

A paper published in Trends in Neuroscience by Nicolas G. Bazan, MD, PhD of the Neuroscience Center of Excellence at LSU Health Sciences Center in New Orleans, reports on the role that the omega-3 fatty acids in fish oil play in protecting cells in the retina from degenerative diseases like retinitis pigmentosa and age-related macular degeneration.

Retinal degeneration - researchers advance understanding

Researchers have labored for decades to understand blindness-inducing neurodegenerative diseases such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP).

First-of-its-kind test on a microchip array will help diagnose retinitis pigmentosa

Rapid genetic testing for eye disease is becoming a reality, thanks to a technology developed at the University of Michigan Kellogg Eye Center.

First human gene mutation that causes extreme farsightedness

Working with an Amish-Mennonite family tree, Johns Hopkins researchers at the Wilmer Eye Institute have discovered what appears to be the first human gene mutation that causes extreme farsightedness.

Researchers discover new molecular mechanism that may allow for stem cell-based therapies to treat eye disorders such as retinal degeneration

The finding also reveals how the retina's own stem cells can be directed to aid the growth of new cells to replace diseased or dying ones in the eye. Study results appear in the June 24 issue of the journal Science.

Bionic eyes from Stanford

Stanford physicists and eye doctors have teamed up to design a "bionic eye," of sorts. On Feb. 22 in the Journal of Neural Engineering, Daniel Palanker, Alexander Vankov and Phil Huie from the Department of Ophthalmology and the Hansen Experimental Physics Laboratory and Stephen Baccus from the Department of Neurobiology published a design of an optoelectronic retinal prosthesis system that can stimulate the retina with resolution corresponding to a visual acuity of 20/80

Preventing eye disease in retinitis pigmentosa

Retinitis pigmentosa (RP) is an inherited eye disease that causes visual disability leading to blindness. Over the last 15 years, researchers have pinpointed defects in dozens of genes causing different forms of RP.

First generation of human retinal cells in the laboratory from human embryonic stem cells

Some of these retinal tissues such as Retinal Pigment Epithelium (RPE) may provide a novel therapeutic strategy for such devastating diseases as macular degeneration, retinitis pigmentosa, and other retinal degenerative diseases.

Potential stem cells treatment for retinitis pigmentosa and other retinal degenerations

A team of researchers from The Scripps Research Institute was able to preserve visual function in mice that were genetically predisposed to developing a profound degenerative disease that destroys their retinas.

Zinc plays a crucial role in blindness

Dartmouth Medical School researchers in their quest to find cures for inherited diseases have found that zinc plays a crucial role in blindness in over one million people worldwide.

Genome research sheds light on Bardet-Biedl syndrome

By comparing the genomes of an alga, a weed and humans, a team of researchers has identified a new gene behind Bardet-Biedl syndrome (BBS), a complex condition marked by learning disabilities, vision loss and obesity.

Discovery shows how single genetic mutation can cause complex disorders

Bardet-Biedl syndrome (BBS), characterized by obesity, learning disabilities and eye and kidney problems, is caused by genetic mutations in the BBS family of genes. Now, researchers who've long studied the condition have discovered that genetic mutations in one of those genes, called BBS4, lead to cell death by disrupting the cells' internal "highway" system.
