Abstract
Age-related macular degeneration (AMD) is
the leading cause of blindness in older individuals. About 30% of Americans age
75 or older have early manifestations characterized by accumulation of subretinal deposits leading to mild-moderate visual
dysfunction, while 7% in this age group have late forms characterized by death
of the retina and growth abnormal blood vessels under the retina leading to
severe vision loss. AMD is a late onset complex trait with environmental, dietary,
and hereditary risk factors. A major limitation in the study of AMD is
the difficulty in diagnosing the maculopathy before
the age of 50 and in a quantitative manner. Currently no such techniques exist.
Professor Alireza Khotanzad
and I have been working together over the past 2 years toward evaluating novel
endpoints for early, qualitative, and possibly quantitative description of AMD. In
my presentation I will (i) present an overview of the
epidemiology, pathology, and pathophysiology of AMD,
(ii) describe the current state of diagnosis and detection
of AMD, (iii) summarize the spline-vessel
matching image registration method we have developed for evaluating novel
endpoints, and (iv) discuss areas in need of novel biomedical approaches to
facilitate the study of AMD.

Eye Institute at the Oregon Health
Sciences University.
Dr. Edwards is conducting National Eye Institute and private
foundation funded research programs in macular degeneration. He is the winner of Career Development Awards
from the Foundation Fighting Blindness and the Research to Prevent Blindness
and the holder of an International Retinal Research Foundation Award. He is a
