Determining what triggers the death of retinal cells, called photoreceptors, could hold the key to stopping blinding disorders caused by a wide range of eye diseases, Yale School of Medicine researchers report in the November journal Investigative Ophthalmology & Visual Science.
Several blinding disorders are known to cause the breakdown of photoreceptors. Caroline Zeiss, associate professor [...]

Rods and cones coexist peacefully in healthy retinas. Both types of cells occupy the same layer of tissue and send signals when they detect light, which is the first step in vision. The incurable eye disease Retinitis Pigmentosa, however, reveals a codependent relationship between the two that can be destructive. When flawed rods begin to [...]

Retinal detachment, a condition that afflicts about 10,000 Americans each year, puts an individual at risk for vision loss or blindness. In a new study in the New England Journal of Medicine, a leading ophthalmologist at NewYork-Presbyterian Hospital/Weill Cornell Medical Center writes, however, that a high probability of reattachment and visual improvement is possible by [...]

Pluripotent stem cells — those, like embryonic stem cells, that give rise to almost every type of cell in the body — can be converted into the different classes of retinal cells necessary for vision, according to a new study from researchers at SUNY Upstate Medical University.
This research points to exciting new possibilities for preventing [...]

Scientists at Schepens Eye Research Institute have found that reducing the levels of vascular endothelial growth factor (VEGF), which is best known as a stimulator of new blood vessel growth, in adult mice causes the death of photoreceptors and Muller glia – cells of the retina that are essential to visual function.
This finding holds implications [...]
