Macular Degeneration Research - Completed Award

James Handa

Wilmer Eye Institute
Baltimore, MD

Title: Advanced Glycation Endproduct Mediated Cholesterol Deposition in Bruch's Membrane
Non-Technical Title:

Duration: April 1, 2005 - March 31, 2007
Award Type: Standard
Award Amount: $99,545

Details:


When looking at AMD eyes under the microscope, the most distinguishing change is basal deposits, or accumulations of material within Bruch’s membrane, a specialized scaffold upon which the retinal pigment epithelium (RPE) attaches. Prior to basal deposit formation, cholesterol (fat) is deposited into Bruch’s membrane. Dr. Handa believes that understanding how cholesterol gets deposited into Bruch’s membrane will help researchers to design targeted new treatments that prevent the onset of AMD or slow the inevitable progression from early to late disease.
