Washington [US]July 9 (ANI): A group of Singaporean scientists have developed a biofunctional thermogel, a type of synthetic polymer, to prevent retinal scarring caused by failed retinal detachment repair surgery, according to a new study. The research findings were published in the journal Nature. Read Also | Sri Lankan Prime Minister Announces Resignation, Amid Economic Crisis Read @ANI’s Story… – Latest Tweet by ANI Digital. Research reveals that proliferative vitreoretinopathy occurs when retinal scar tissue prevents the retina from healing and falling back into place. And it’s said that it accounts for more than 75 percent of failed retinal detachment surgeries, and can result in vision loss or blindness if left untreated. Current treatment options for PVR are limited to surgical removal of this scar membrane with preserved visual recovery. This work highlights the potential use of synthetic polymers alone to modulate cellular behavior and, for the first time, offers a novel th

The eye’s light-sensing retina taps different circuits depending on whether it produces image-forming vision or performs non-visual functions such as regulating pupil size or the sleep/wake cycle, according to a new mouse study from the National Eye Institute. NEI) and the National Institute of Mental Health (NIMH). These findings could have implications for understanding how our eyes help regulate mood, digestion, sleep and metabolism. NEI and NIMH are part of the National Institutes of Health. “We know a lot about the pathways involved in image-forming vision, but until now it was unknown whether and how non-image-forming visual behavior depended on these same pathways in the eye,” says Johan Pahlberg, Ph.D., head of Photoreceptor Physiology Group at NEI and senior author of the study. Vision begins when light enters the eye and hits the light-sensing photoreceptors of the retina. Photoreceptors transfer signals through several layers of retinal neurons before they are sent to th
