Results of RPE cell transplantation encouraging in dry AMD

Subretinal transplantation of retinal pigment epithelial cells derived from human embryonic stem cells appears to be well tolerated in patients with dry age-related macular degeneration and geographic atrophy, according to the interim results of a phase 1/2 clinical trial.
Improved visual acuity was achieved in a subgroup of patients with better baseline vision, some of whom underwent cell injection with a new subretinal delivery system (SDS) without vitrectomy or retinotomy.
Christopher D. Riemann, MD, who presented the results at the virtual Association for Research in Vision and
