NCT03944239

Brief Summary

This project intends to transplant a clinical level human embryonic stem cells derived retinal pigment epithelium into subretinal space to treat eetinitis pigmentosa(RP) diseases. Through the statistical analysis EDTRS, BCVA, OCT, ERG, Fluorescein angiography, Ophthalmic AB ultrasound changes between before and after the treatment to assess the efficacy and safety 0f RPE transplants to treat RP disease.
