Figure 8: Long-term follow-up of outer retinal function by b-wave ERG analysis. Mean maximal b-wave amplitude ERG responses to light flashes in increasing luminance levels were recorded following dark (squares) or light (circle) adaptation, in transplanted (closed) or control (open) eyes at indicated weeks (W) prior to (W0) or 2–10 weeks following cell transplantation. Data are presented as mean ± SE.
