Read our Macular Degeneration research guide →Researchers are studying how narrowing of blood vessels in the eye might contribute to geographic atrophy—an advanced form of dry age-related macular degeneration (AMD) where the light-sensitive tissue in the center of the eye gradually breaks down. This is an observational study, meaning researchers will use specialized imaging scans to look for a connection between vessel narrowing and the development of this condition. No new medication is being tested; instead, the focus is on understanding the underlying causes of the disease.
Currently, there are limited treatment options for geographic atrophy. Researchers believe that if they can better understand whether narrowed blood vessels play a role in causing or worsening this condition, they may be able to develop new therapies in the future.

You will undergo specialized eye imaging scans at the Cole Eye Institute to examine the blood vessels and tissues in your eye. These noninvasive scans—similar to ultrasounds or CT scans—will help researchers look for narrowing of the ophthalmic artery and compare your two eyes. The study will involve one or more visits, and the imaging procedures are painless, though you may need to sign consent for the use of imaging contrast dye during some scans.
