This led researchers to investigate the light sensitive cells (photoreceptors) mediating these effects.
It has tiny photoreceptors that detect polarized light, allowing it to perceive very dark and very bright objects in its field of view, discerning predator from prey in the murky ocean waters it calls home.
According to the trial sponsor, UK biotechnology company ReNeuron, pre-clinical studies have demonstrated that retinal implantation of human retinal progenitor cells (hRPC) have the potential to preserve existing photoreceptors, potentially reducing or halting further deterioration of vision.
Summary: TEHRAN (FNA)- Duke University researchers have developed a handheld probe that can image individual photoreceptors in the eyes of infants.
The team did so by changing Muller glia cells in the retina into rod photoreceptors. The latter are light-sensitive cells in the back of the eye that transmit information to the brain when activated, and unfortunately these cells are unable to regenerate on their own in mammals.
'Rods allow us to see in low light, but they may also help preserve cone photoreceptors, which are important for color vision and high visual acuity,' explained study co-author Dr Thomas Greenwell.
Since photoreceptors, produced in the eye, are useless without retinal, one needs a continuous supply of retinal molecules to see.
A full-field electroretinography response was not detected (this measures the electrical responses of various cell types in the retina, including the photoreceptors, inner retinal cells, and the ganglion cells), but this does not necessarily imply total blindness.
MONDAY, May 7, 2018 (HealthDay News) -- Survivors of Ebola virus disease (EVD) have localized pathological changes in photoreceptors, according to a study published online May 3 in JAMA Ophthalmology.
MicroRNA modulators may be functionally delivered to the eye, including the retina and photoreceptors, in animal models.
"We usually classify photoreceptors into rods or cones only.
