title: Age-related macular degeneration.
abstract: Age-related Macular Degeneration (AMD) is the major cause of vision loss after age 50 in the United States. Although an important association of the complement cascade with AMD has recently been made, we still do not understand the pathogenesis of the disease. AMD is characterized by loss of the retinal pigment epithelium (RPE) within the macula (i.e., the center of the retina), and in turn, loss of the overlying foveal photoreceptors. Since RPE and photoreceptors can both be generated from stem cells using cell culture, there is hope for future cell replacement therapy. But, aging changes in Bruch's membrane, the scaffold on which the RPE are anchored, may complicate such therapy, and require surgical repair of Bruch's membrane to provide a suitable environment for cell survival and function. We have referred to such a multipronged approach of surgical reconstruction of the macular architecture in conjunction with cell transplantation as Maculoplasty.
