[Research progress in optogenetic therapy for retinitis pigmentosa].

Retinitis pigmentosa (RP) is a group of inherited retinal diseases characterized by progressive loss of photoreceptor cells and retinal pigment epithelium function. Its treatment has long been a focus and challenge in ophthalmic research. Despite advances in therapies such as stem cell transplantation, gene therapy, and retinal prosthetic implants, many difficulties remain.
