This trial is investigating the feasibility of transplanting Retinal Pigment Epithelial (RPE) cells made from human embryonic stem cells in cases of Stargardt's Macular Dystrophy. The trial is being conducted at the CHA Bundang Medical Center in Gyeonggi-do, Republic of Korea. Participants will undergo retinal transplantation of approximately 50,000 RPE cells and will be assessed for complications (including tumour formation) and for evidence of engraftment of the transplanted cells. The trials plans to recruit three subjects with Stargardt's syndrome by December 2014.
