Calming chaotic signals
The degeneration of light sensing retinal cells in conditions like RP causes a surge of chaotic signals in nerve cells at the back of the eye, which interfere with remaining vision and make sight loss even worse.
Reporting in the journal “Neuron”, researchers in California describe how they have successfully used existing drugs to quieten this interference and improve vision in mice with RP, providing hope that this approach could be used in humans to slow sight loss.

Encouraging safety results from early tests of an optogenetics approach
Biotechnology company GenSight has announced positive safety outcomes from the first group of three patients to receive its innovative new treatment, which combines a special type of gene therapy (optogenetics) with a wearable device.
GenSight will now proceed to give the next small group a larger dose of gene therapy and follow their progress.
