Pluripotent stem cells: A therapeutic source for age-related macular degeneration.

ABSTRACT: Age-related macular degeneration (AMD) leads to progressive loss of central vision in the elderly. At a cellular level, there is aging of the retinal pigment epithelial (RPE) cells, and accumulation of lipofuscin that interferes with the proper functioning of RPE which eventually leads to apoptosis. Treatment depends on the stage of the disease. Wet AMD which has neovascularization is managed by local therapies such as laser photocoagulation and photodynamic therapy and is managed with injections of antivascular endothelial growth factor-based therapy. Unlike the wet AMD, an effective therapy does not exist for dry AMD and geographic atrophy. Cell replacement therapy has shown promise. This review discusses the opportunities in the various types of cell-based therapy, their limitations, and what is possible for India.
