Age-related macular degeneration (AMD) is the leading cause of legal blindness in the western nations beyond 50 years of age. The most frequent cause for severe visual loss is the growth of neovascular membrances from the choroid into the subretinal space. This usually results in irreversible degeneration of the overlying retina. Surgical removal of the membrane is feasible, however, usually results in functional loss of apposing retinal photoreceptors since retinal pigment epithelial (RPE) cells are removed concurrently due to their tight adherence to the neovascular complex. Therefore, various attempts have been undertaken to fill the resulting RPE cell defect with either heterologous or autologous RPE cell transplants. So far cell survival, function and subsequent visual function has been disappointing. To minimize trauma and resulting dedifferentiation harvesting in the eye and transplantation in whole sheets and without temporary removal from the eyes would be desirable. This may be achieved by isolating grafts consisting of choroid, Bruch's membrance and RPE cells from the peripheral retina and transplantation of this graft under the neurosensory retina after removal of the choroidal neovascularization. However, the choroidal component of such a graft would be expected to interfere with diffusion of metabolites to and from the retina. Therefore, outcome would be expected to be better if the choroidal tissue would be removed before translocation. In preclinical experiments we used a 308 nm UV AIDA excimer laser to microablate choroidal tissue from such a graft in human donor eyes.
