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.
A new technique that has the potential to treat inherited diseases by removing genetic defects has been shown for the first time to hinder retinal degeneration in rats with a type of inherited blindness, according to a Cedars-Sinai study.
The Dompé biopharmaceutical company announced today that the Committee for Orphan Medicinal Products of the European Medicines Agency (EMA) has officially designated recombinant human Nerve Growth Factor (rhNGF) - the investigational biotech molecule developed by Dompé based on research by Nobel Laureate Rita Levi Montalcini - as an orphan drug for the treatment of neurotrophic keratitis.
The American Academy of Ophthalmology will pay tribute to outstanding eye physicians and surgeons who have made significant achievements in various areas of the profession. These range from scientific innovation and humanitarian service to education and advocacy. The honorees will be recognized AAO 2015, the Academy's 119th annual meeting in Las Vegas.
Scientists have good news for patients who suffer from currently untreatable dry age-related macular degeneration (dry AMD). In a new study, researchers identified a potential target for future therapies to slow the progression of the blinding condition. Published in Investigative Ophthalmology & Visual Science, the findings indicate that treatments currently used for other conditions could also work for dry AMD.
The animal brain is so complex, it would take a supercomputer and vast amounts of data to create a detailed 3-D model of the billions of neurons that power it.
A collaboration between scientists in the UK and the USA has shown that gene therapy can give life-long protection to the light-sensitive photoreceptor cells responsible for colour vision in a mouse model of the most common inherited eye disorder.
Around 600,000 Austrians suffer from diabetes. This condition is frequently associated with serious retinal disorders. Along with age-related macular degeneration, diabetic retinal degeneration is one of the most common causes of blindness. The Department of Ophthalmology and Optometry at MedUni Vienna was chosen by the European Society of Retina Specialists (EURETINA) to coordinate the development of up-to-date treatment and diagnostic guidelines.
By growing two types of stem cells in a "3-D culture" and measuring their ability to produce retinal cells, a team lead by St. Jude Children's Research Hospital researchers has found one cell type to be better at producing retinal cells.
Spider-like cells inside the brain, spinal cord and eye hunt for invaders, capturing and then devouring them. These cells, called microglia, often play a beneficial role by helping to clear trash and protect the central nervous system against infection. But a new study by researchers at the National Eye Institute (NEI) shows that they also accelerate damage wrought by blinding eye disorders, such as retinitis pigmentosa.
The American Society of Human Genetics (ASHG) has named Robert L. Nussbaum, M.D., chief medical officer of invitae and clinical professor of medicine (volunteer) at the University of California, San Francisco (UCSF); Roderick R. McInnes, CM, M.D., Ph.D., director of the Lady Davis Institute at the Jewish General Hospital and Alva chair in human genetics, Canada Research chair in neurogenetics, and professor of human genetics and biochemistry at McGill University; and Huntington F. Willard, Ph.D., president and director of the Marine Biological Laboratory and professor of human genetics at the University of Chicago; as the 2015 recipients of its annual Award for Excellence in Human Genetics Education.
Shaomei Wang, MD, PhD, a research scientist in the Eye Program at the Cedars-Sinai Board of Governors Regenerative Medicine Institute, received a $4.9 million grant from the California Institute for Regenerative Medicine to advance her work in retinitis pigmentosa, a type of degenerative retinal disease.
Myopia or short-sightedness is becoming more common across Europe, according to a new study led by King's College London. The meta-analysis of findings from 15 studies by the European Eye Epidemiology Consortium found that around a quarter of the European population is short-sighted but it is nearly twice as common in younger people, with almost half (47 per cent) of the group aged between 25 and 29 years affected.
Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the LSU Health New Orleans Neuroscience Center of Excellence, discovered a protein in the retina that is crucial for vision. The paper reports, for the first time, the key molecular mechanisms leading to visual degeneration and blindness.
Research led by Nicolas Bazan, MD, PhD, Boyd Professor, Ernest C. and Yvette C. Villere Chair of Retinal Degeneration Research, and Director of the Neuroscience Center of Excellence at LSU Health New Orleans, has discovered gene interactions that determine whether cells live or die in such conditions as age-related macular degeneration and ischemic stroke.
Finding genes for retinal degenerations has immediate benefits for people living with blindness and vision loss, their families, and their physicians. Establishing a genetic cause confirms the clinical diagnosis at the molecular level, helps predict the future visual prognosis, suggests therapies, and allows some patients to join clinical trials. While more than 200 genes for retinal degenerations have been identified, approximately 40-50% of cases remain a mystery.
The aging process affects everything from cardiovascular function to memory to sexuality. Most worrisome for many, however, is the potential loss of eyesight due to retinal degeneration.
An established class of drugs, traditionally used to control HIV/AIDS infections, could soon be harnessed to treat the leading cause of blindness and visual impairment in the UK, for which currently there exists no cure.
It's well known that battlefield explosions can cause hearing loss, but veterans may be surprised to learn that their vision may also suffer — sometimes weeks or months after combat exposure.
The loss of eyesight, often caused by retinal degeneration, is a life-altering health issue for many people, especially as they age.
Blind cave fish may not be the first thing that comes to mind when it comes to understanding human sight, but recent research indicates they may have quite a bit to teach us about the causes of many human ailments, including those that result in loss of sight.
