Science Briefs – Edition 32

  • Major progress made in blindness caused by cellular degeneration.
  • New model to examine Usher Syndrome.
  • Gene therapy used in Toronto.
  • And, about a dozen stories about the science, medicine and prevention of blindness from all over the world.

Editorial By Chris Hofstader

This week, the story in Science Briefs that I found most interesting was the one about progress related to blindness caused by cellular degeneration as I knew little about that cause for blindness and got to learn some new things. I always find Science Briefs to be a bit uplifting as so often it demonstrates positive progress and, on a personal level, I'm a science enthusiast and enjoy reading about science in general.

We hope you enjoy this edition of Science Briefs.


World Blind herald does not write the stories to which we link in Science Briefs, we gather them, curate them and bring them to our readers. We are not scientists ourselves and cannot guarantee the validity of the stories in this digest. We do, however, want to be very clear that you should not attempt any of the medical interventions mentioned in Science Briefs without first consulting a professional ophthalmologist and discussing it with them.

Scientists Achieve Promising Results Towards Restoring Vision In Blindness Caused By Cellular Degeneration In The Eye

A preclinical study using stem cells to produce progenitor photoreceptor cells — light-detecting cells found in the eye — and then transplanting these into experimental models of damaged retinas has resulted in significant vision recovery. This story comes to us from:

University of Houston researcher builds new model to examine Usher Syndrome

Usher syndrome, a rare inherited genetic disease, is a leading cause of combined deafness and blindness with type 2A (USH2A) being the most common form. USH2A, caused by mutations in the USH2A gene, can include hearing loss from birth and progressive loss of vision, prompting retinitis pigmentosa (RP). RP affects the retina, the eye’s light-sensitive layer, leading to a breakdown of the light-sensitive cells in the retina which initially leads to night blindness followed by progressive loss of daily vision. Currently no treatment exists for USH2A. This story comes to us from: EurekAlert.
