New procedure "can restore sight"

New procedure "can restore sight"

A new type of procedure may be able to restore sight in people suffering from retinitis pigmentosa, experts suggest.

The study has been carried out on mouse models by researchers from the Friedrich Miescher Institute (FMI) and the Institut de la Vision, who have succeeded in reactivating cones in mice"s eyes.

In retinitis pigmentosa, cones, which are responsible for diurnal vision, are damaged but not destroyed, unlike rods.

Experts believe that restoring these cones may lead to the effects of the condition being reversed.

Researcher Jose Alain Sahel explained: "We integrated the clinical approach as soon as we obtained the first fundamental results of this work. Thanks to non-invasive high-resolution retinal imaging techniques, we can now target patients to whom this therapy could be applied."

It comes after research presented at recent annual meeting of the Associated Professional Sleep Societies LLC, suggested that colour perception may be restored during sleep after gradually becoming less neutral throughout the day.
