Will Retinal Implants Restore Vision

EPFL researchers have developed a new type of retinal implant for people who have become blind due to the loss of photoreceptor cellsphotoreceptor cellsA photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes.https://en.wikipedia.org › wiki › Photoreceptor_cellPhotoreceptor cell – Wikipedia in their retinas. The implant partially restores their visual field and can significantly improve their quality of life.

Scientists Have Created an Artificial Retina Implant That Could Restore Vision to Millions. Scientists have developed a retinal implant that can restore lost vision in rats, and are planning to trial the procedure in humans later this year.

Additionally, the researchers say their implant is larger, which improves image quality by widening the wearer’s visual field. In their Communications Materials article, the Swiss researchers noted that retinal implants have been tested mostly in blind patients affected by retinitis pigmentosa.

Can vision be restored after?

Vision loss after retinal or cerebral visual injury (CVI) was long considered to be irreversible. However, there is considerable potential for vision restoration and recovery even in adulthood. Here, we propose the “residual vision activation theory” of how visual functions can be reactivated and restored.

Is there a cure coming soon for retinitis pigmentosa?

There’s no cure for RP, but low vision aids and rehabilitation (training) programs can help people with RP make the most of their vision. You can also talk with your eye doctor about vitamins and supplements for RP. Vitamin A may help slow vision loss from the common forms of RP.
