Gene Therapy Trial to Restore Sight in Retinitis Pigmentosa – Labiotech – 10-Jan-2018
GenSight using gene therapy and a wearable device to restore sight in patients with retinitis pigmentosa.
Medicines and Healthcare Regulatory Agency has accepted application to run a clinical trial in the UK.
Gene therapy encodes for a protein sensitive to light into specific neurons.
Goggles capture images and transform them into light patterns that stimulate the proteins.
GS030 phase I/II trial should measure the outcome in early 2019.
Retinitis pigmentosa is a genetic disease that leads to blindness by age 40.
Therapy could be extended to other retinal diseases such as dry-AMD.
Bionic Implant to Restore Vision Enters Clinical Trials – Labiotech – 20-Oct-17
Pixium Vision has received approval in France to start a clinical trial.
PRIMA is a miniature wireless sub-retinal implant.
Will be implanted into 5 patients with vision loss due to advanced dry age-related macular degeneration (dry-AMD).
PRIMA electrodes can detect infrared signals and transform them into electrical impulses to be transmitted through the optic nerve.
4 million people suffer from AMD with no treatment options available.
Blind Patients to Test Bionic Eye Brain Implants – Technology Review – 18-Sep-2017
The company, Second Sight, is launching a clinical trial for a brain implant designed to restore vision.
The device, called the Orion, is a modified version of the company’s current Argus II bionic eye, which involves a pair of glasses outfitted with a camera and an external processor.
Anyone who had vision but has lost it from almost any cause could potentially be helped by the Orion technology.
Due to this device patients can distinguish light from dark and recognize the outlines of objects in their view, but they can’t see color.
Meet the film-maker with the camera eye – BBC News – 20-Jul-17
Rob Spence is blind in one eye.
Nine years ago he replaced his eye with a tiny video camera.
It’s not connected to his optic nerve but sends its footage to a receiver.
Inspired by his bionic man toy!
First nanoengineered retinal implant could regain functional vision – Kurzweil AI – 16-Mar-2017
The nanowires provide higher resolution than anything achieved by other devices.
Closer to the dense spacing of photoreceptors in the human retina.
Arrays of nanowires simultaneously sense light and electrically stimulate the retina.
Could help people with neurodegenerative diseases including macular degeneration, retinitis pigmentosa, and loss of vision due to diabetes.
Bionic Eye to Begin Human Trials (VIDEO) – Robotics Trend – 29-Jan-2016
Signal from two cameras mounted in glasses is processed and converted real-time into stimulation of implant which is then interpretted as vision by the brain.
Surgery takes less than 3 hours.
Scientists at the University of New South Wales hoping to implant Phoenix99 bionic eye in 12 patients over the next two years.
Currently low resolution but can only improve.
Bionic eye enables woman to see again (video) – BBC News – 5-Jan-2015
Retinitis pigmentosa (RP) caused patient to lose vision. No cure available.
3x3mm chip implanted in back of eye to replace light-sensitive retinal cells.
After 6 months able to recognise basic shapes.
Operation done at John Radcliffe Hospital (JR) in Oxfordshire, UK.
Robotic medical device could help millions – Today’s Medical Developments – 22-Sep-2015
University of Arkansas at Little Rock (UALR) to develop a Wearable Robotic Object Manipulation Aid (W-ROMA).
Device to be worn on user’s hand would communicate with its wearer about the location, shape, and size of objects in a meaningful, yet unobtrusive way.
Easier for visually impaired people to remove obstacles, such as a chair in their path, and perform essential tasks, such as finding a door handle.
Bionic eye implant world first – BBC News – 21-Jul-2015
Previously only tested on rare eye conditions Second Sight’s Argus II implant has now been successfully tested in a patient with dry age-related macular degeneration which affects around half a million people in the UK. This condition results in loss of central vision and the Argus II provides just enough detail to locate large objects such as doors and windows in a room. A miniature video camera worn on a pair of glasses transmitted wirelessly to an array of 60 electrodes attached retina’s remaining healthy cells which send the information to the brain. The implant is designed to last the lifetime of the patients.
Argus II retinal implant trials successful – KurzweilAI – 24-Jun-2015
Bionic eye significantly better life for 89 percent of trial subjects in 3 year study.
Classic technology meets healthcare scenario – new versions already available increasing visual pixels from 60 to 1500 – imagine if drugs had improved their efficacy at that rate for the last 100 years, we’d all be disease free by now.
