Replacement of the RPE monolayer [PDF]
Eye, 2009 There are numerous scenarios in which replacing the diseased RPE monolayer is an attractive but as yet unrealised goal. The proof of concept that vision can be improved by placing a healthy neuroretina onto a different, healthy, underlying RPE layer is demonstrated in patch graft transplantations.
