Doctors Aim To Restore Sight To The Blind Wordlesstech
Could optogenetics restore vision to the blind? posted on october 19, 2016 by b eaton earlier this year, the first human trials of optogenetics were launched by retrosense therapeutics , a michigan based biotechnology company seeking to restore sight to patients with retinal degenerative conditions through the use of innovative gene therapy. A blind man has regained limited vision thanks to a new kind of gene therapy. this demonstration could represent the tip of the iceberg for the next generation of vision and hearing therapies. One texas company, retrosense therapeutics, attempted a form of optogenetics on a human patient, giving a blind woman treatments to restore her vision. the results of that study are yet unknown, but retrosense has a total of four patients now. Prosthetics and optogenetics can be implemented in either mode, but the use of chemical photoswitches is currently limited to downstream implementations. even so, given the high density of human foveal ganglion cells, the ultimate chemical photoswitch treatment could deliver cost effective, high resolution vision for the blind. Optogenetic treatment restores partial vision in retinitis pigmentosa. an international research team has shown that optogenetic therapy has helped to partially regain visual function in a patient with retinitis pigmentosa. this is a milestone towards a gene therapy that could restore vision. a patient performs a series of tests demonstrating.

Blind mice given human cone opsins could then see well enough to explore new toys in their … [ ] environment by sight. getty “chrimson is incredibly fast, but it’s not very sensitive,” says john flannery, an optogenetics researcher at uc berkeley. he is experimenting with opsins found in the cones of the human retina that are sensitive. A 58 year old man who has been blind for years now sees well enough to make out shapes, including the white lines of a crosswalk. the advancement comes thanks to a technology called “optogenetics,” a kind of gene therapy that delivers light sensing molecules into the eye.
