Dry AMD

This term refers to the “dry” form of Age Related Macular Degeneration (AMD). AMD is a disease that effects the retina of the eye. AMD results in a loss of vision in the center of the visual field, in an area of the retina called the macula. The disease is caused by the death of a cell type called a “Retinal Pigment Epithelial cell” (RPE) that normally functions to support, protect and nourish the retina. AMD occurs in “dry” and “wet” forms. The dry form is characterized by the presence of yellow deposits of a waste material called “drusen” that is normally removed by RPE cells. This leads to blind spots in the center of vision. BioTime’s subsidiary Cell Cure Neurosciences is using stem cells to create RPE cells to address the more prevalent “dry” form of AMD which effects 90% of current AMD patients.
