A genetic mutation that contributes to sight loss in children has been identified by scientists. The mutation was identified in patients with a disease known as ocular coloboma, which causes part of the eye to be missing at birth.
In a study published in Scientific Reports, researchers from Magdeburg University (Germany) and The Chinese University of Hong Kong report that for rats and mice, repetitive transorbital alternating current stimulation (rtACS) may help preserve visual neurons from cell death after injury.
Is what you're looking at an object, a face, or a tree? When processing visual input, our brain uses different areas to recognize faces, body parts, scenes, and objects. Scientists at KU Leuven (University of Leuven), Belgium, have now shown that people who were born blind use a 'brain map' with a very similar layout to distinguish between these same categories.
Researchers from the University of Eastern Finland have discovered a likely cause for visual impairment and eventual loss of vision in the Finnish variant of Neuronal Ceroid Lipofuscinosis (NCL). Visual impairment associated with the Finnish variant of NCL may be caused by impaired retinal waste management system, including autophagy, leading primarily to the death of photoreceptor cells that are of essential for vision.
Led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, a study in mice finds that development of age-related macular degeneration (AMD) could be arrested by switching from a high-glycemic to a low-glycemic diet.
In a small and preliminary clinical trial, Johns Hopkins researchers and their collaborators have shown that an experimental gene therapy that uses viruses to introduce a therapeutic gene into the eye is safe and that it may be effective in preserving the vision of people with wet age-related macular degeneration (AMD).
Researchers from the University of Liverpool have conducted a study of Ebola survivors to determine if the virus has any specific effects on the back on the eye using an ultra widefield retinal camera.
Scientists at the University of Birmingham have developed a type of eye drop which could potentially revolutionize the treatment of one of the leading causes of blindness in the UK.
Novel therapeutic approaches and advances in the treatment of uveitis, a sight-threatening inflammation of the eye caused by infection or an autoimmune response, are presented in a special issue of Journal of Ocular Pharmacology and Therapeutics.
In 2009, Joan Coates, a veterinary neurologist, along with other researchers at the University of Missouri and the Broad Institute, found a genetic link between degenerative myelopathy (DM) in dogs and amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease in people. Now, Coates and Michael Garcia, an associate professor in the Division of Biological Sciences, have found that a biomarker test that helps diagnose ALS also can assist with determining a diagnosis for degenerative myelopathy.
