Representative retinal appearance and morphologic features before and after cell transplantation for patient 6. Retinal structures were imaged by optical coherence tomography (OCT) before and after surgery. a OCT imaging with horizontal scanning along the superior temporal macular area before surgery. Notice the characteristic of local photoreceptor atrophy. b On postoperative day 7, a mass of transplanted cells (arrows) is most evident as dense medium reflectivity, which is located between the degenerated photoreceptor layer and retinal pigment epithelium layer. c Transplanted cells are still present although the thickness has been noticeably reduced (arrows) 1 month after surgery
