Exercise can slow or prevent the development of macular degeneration and may benefit other common causes of vision loss, such as glaucoma and diabetic retinopathy, new research suggests.
A new approach in ophthalmology that offers a revolutionary alternative to corneal transplantation has just been developed by researchers and clinicians in North America, Europe, and Oceania.
New eye drops could prevent vision loss after retinal vein occlusion, a major cause of blindness for millions of adults, a study by Columbia University researchers has found.
Researchers at Istituto Italiano di Tecnologia has led to the development of an artificial liquid retinal prosthesis to counteract the effects of diseases such as retinitis pigmentosa and age-related macular degeneration that cause the progressive degeneration of photoreceptors of the retina, resulting in blindness. The collected data show that this innovative technique is valid to restore the photoreceptive capacity of retinal neurons while preserving their spatial resolution, laying a solid foundation for future clinical trials in humans.
The brain's ventral lateral geniculate nucleus (vLGN) receives signals from the eye, but it is not associated with classical image-forming. For decades little was known about this brain region's cellular structure and purpose. In a new study, Fralin Biomedical Research Institute at VTC neuroscientists reveal newly identified brain cell subtypes unique to this region that form a striking layered formation.
Hundreds of patients have been diagnosed and many new genetic causes of disease discovered in a UK National Health Service programme pioneering the use of whole genome sequencing. The study, led by researchers at the National Institute for Health Research BioResource together with Genomics England, demonstrates that standardized sequencing whole genomes of large numbers of people can improve the diagnosis and treatment of patients with rare diseases.
After a brain injury, cells that normally nourish nerves may actually kill them instead, a new study in rodents finds. This 'reactive' phenomenon may be the driving factor behind neurodegenerative diseases like glaucoma, a leading cause of blindness.
A case of pink eye is now reason to be tested for COVID-19, according to University of Alberta researchers. Coughing, fever and difficulty breathing are common symptoms of the illness, but a recent case study involving an Edmonton woman and published in the Canadian Journal of Ophthalmology has determined that conjunctivitis and keratoconjunctivitis can also be primary symptoms.
Millions of sufferers of glaucoma might someday benefit from a study released in STEM CELLS in which a "disease in a dish" stem cell model was used to examine the mechanism in glaucoma that causes retinal ganglion cells (RGCs) to degenerate, resulting in loss of vision.
How common asthma was among children with various developmental disabilities (including attention-deficit/hyperactivity disorder, autism spectrum disorder and vision, hearing or speech delay) was compared to children without disabilities in this survey study.
