Researchers at the Stanford University School of Medicine have developed two inexpensive adapters that enable a smartphone to capture high-quality images of the front and back of the eye. The adapters make it easy for anyone with minimal training to take a picture of the eye and share it securely with other health practitioners or…
Retinitis pigmentosa, a blinding eye disease that is caused by the same genetic defect in both dogs and humans, was successfully corrected by a University of Pennsylvania research team that used gene therapy in afflicted dogs. The retinitis pigmentosa cure holds promise for eventual treatment in humans as well. Both humans and dogs can contract…
Researchers reporting in the January issue of Cell Stem Cell, a Cell Press publication, have identified adult stem cells of the central nervous system in a single layer of cells at the back of the eye. That cell layer, known as the retinal pigment epithelium (RPE), underlies and supports photoreceptors in the light-sensitive retina. Without…
Hiding in the back of your eye are stem cells from the central nervous system, scientists have discovered. The stem cells in question were found in a special layer of cells in the eye called the retinal pigment epithelium, or RPE. Just one cell thick, the layer lies underneath the retina, the eye’s light sensor….
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…
