A bionic prosthetic eye that speaks the language of your brain
Sheila Nirenberg of Cornell University has been trying to work out how the retina in your eye communicates with your brain — and judging by a recent talk at TEDMED, it seems like she’s actually cracked it. Nirenberg produced mathematical equations that, with startling accuracy, encode images into neuron pulses that can be understood by an…
Calvert Labs and eyecro Announce Strategic Partnership in Ocular Research
Scott Township, PA – June 10, 2013 – Calvert Labs and eyecro, two leading providers in early-stage ocular drug research and development, announced today that they have entered into a strategic partnership to expedite preclinical drug development activities. “This partnership will facilitate a seamless transition from the discovery and non-GLP stage of drug development to…
New Report from Prevent Blindness America Shows Sharp Increase in Eye Disease Prevalence
According to the 2012 update of the “Vision Problems in the U.S.” report, a study released today by Prevent Blindness America and the National Eye Institute, the number of those ages 40 and older with vision impairment and blindness has increased 23 percent since the year 2000. In addition, a preliminary update to the 2007…
Retina Protein That May Help Conquer Blindness Discovered
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. The research reveals events that may…
‘Positive Stress’ Helps Protect Eye from Glaucoma
Researchers increased the resistance of cells to damage by repeatedly exposing the mice to low levels of oxygen similar to those found at high altitudes. The stress of the intermittent low-oxygen environment induces a protective response called tolerance that makes nerve cells — including those in the eye — less vulnerable to harm. Stress is…
Lab-Grown Retina from Stem Cells Responds to Light
…stem cell researchers have struggled to coax the malleable cells to form the 10 layers of the retina. And, crucially, no one had, before now, produced lab-grown retinal cells that they demonstrated would respond to light.Researchers at Johns Hopkins pulled it off, they reported in a paper published recently in Nature Communications. They cultivated a…
