Holz FG, Strauss EC, Schmitz-Valckenberg S, van Lookeren Campagne M. Geographic atrophy: clinical features and potential therapeutic approaches. One possible therapeutic approach would be to support and replace the failing RPE cells of affected patients, and indeed moderate success of surgical procedures in which relatively healthy autologous RPE from the peripheral retina of the same eye was transplanted under the retina in the macular area suggested that RPE replacement could be a means to attenuate photoreceptor cell loss. Am J Epidemiol 1983; 118:132–151. Eye injections are done in the clinic. Here, we review the concept of cell-based therapy of AMD and provide an update on current progress in the field of RPE transplantation. The following suggestions can ease daily tasks: Use optical devices such as magnifiers, telescopes, and closed-circuit TVs. Age-related macular degeneration affects 30% patients older than 75 years. A local anaesthetic injection, drops or gel are used to relieve discomfort and the injections are well tolerated in most cases. One possible therapeutic approach would be to support and replace the failing RPE cells of affected patients, and indeed moderate success of surgical procedures in which relatively healthy autologous RPE from the peripheral retina of the same eye was transplanted under the retina in the macular area suggested that RPE replacement could be a means to attenuate photoreceptor cell loss.

Making Biological Sense of Genetic Studies of Age-Related Macular Degeneration. Int J Mol Sci. The procedure is quick. This prompted exploration of the possibility to use pluripotent stem cells (PSCs) as a potential source for “healthy and young” RPE cells for such cell-based therapy of AMD. The procedure uses laser light to destroy or seal off new blood vessels to prevent leakage. A vision rehabilitation specialist can determine which are best for each individual.
