The emerging therapy performed well in several previous lab studies funded by the Foundation Fighting Blindness. Spark Therapeutics vision-restoring RPE65 gene therapy has received marketing approval from the U.S. Food and Drug Administration, becoming the first gene therapy to gain regulatory approval in the U.S. for the eye or any inherited condition. Together, the injection and goggles attempt to replicate the work of light-sensing cells called photoreceptors, which don't work well in people with retinitis pigmentosa. The MarketWatch News Department was not involved in the creation of this content. In some patients, it may actually improve vision, light sensitivity, and ability to see and navigate in the dark, says Christine Kay, MD, director of retinal genetics at Vitreoretinal Associates in Gainesville, FL. February 8, 2023 The Food and Drug Administration (FDA) has granted Fast Track designation to EA-2353 for the treatment of retinitis pigmentosa. This is exciting because the potential lies in the possibility that these repaired genes can now be placed back into the donor eye as a cure for retinitis pigmentosa. A single injection of Luxturna delivers a healthy copy of the RPE65 gene directly to the retina. To assess the safety of unilateral subretinal administration of OCU400 in patients with retinitis pigmentosa associated with NR2E3 and RHO mutations and in patients with LCA due to mutation(s) in CEP290 gene (LCA10).

Always consult with a qualified medical professional about your specific circumstances. The therapy, called QR-421a, is injected into the retina and allows cells to produce a healthier version of the USH2A protein. For the nutrients that feed our cells to reach their destination, proteins embedded in the cell membrane often must shuttle what's needed across the threshold. ProQR Therapeutics is developing a gene therapy that could stop vision loss in people with retinitis pigmentosa and Usher syndrome caused by a mutation in the USH2Agene. Hope to hear from you soon!

Symptoms Secondary Effects Diagnosis Treatment Retinitis pigmentosa (RP) is a genetic eye disease that causes the retina to break down. After rod photoreceptors are eliminated, gradual degeneration of cone photoreceptors occurs resulting in gradual constriction of side vision that eventually causes tunnel vision. The glasses send images to the device, which stimulates light-sensing cells in the retina and transmits these images to the brain.Earlier this year, Second Sight Medical Products announced a redesigned set of glasses for use with previously implanted Argus II systems, but the glasses are not yet commercially available.
