Researchers from the University of Louisville have discovered a way to revitalize cone receptors that have deteriorated as a result of retinitis pigmentosa (RP), potentially leading to therapies for preserving or recovering central vision in patients with RP.
The researchers reportedly found that replenishing glucose under the retina and transplanting healthy rod stem cells into the retina restore function of the cones. They were reportedly able to successfully restore cone access to glucose by first transplanting rod-specific induced pluripotent stem cells beneath the retina, and second by injecting glucose directly into the subretinal space.
The research was recently published in the journal Cell Reports.
