Research and Training

NEI is a leader in vision research. In addition to the work we do in our own facilities, we support outside research that advances the prevention and treatment of eye diseases and vision problems.

The National Eye Institute (NEI), part of the National Institutes of Health (NIH), is the lead federal agency for vision research, fostering scientific breakthroughs at the frontiers of vision research.

Research conducted at NEI (Intramural Research Program)

The NEI intramural research program conducts research in vision science and ophthalmology at our laboratories and clinical center located on the main NIH campus in Bethesda, Maryland. We also develop the next generation of vision researchers through institutional research training and clinician-scientist development. The intramural program functions as an in-house resource of scientists and clinicians tackling high-risk, high-reward research. 

Research funded by NEI

NEI funds research and training opportunities at universities, medical centers, and other institutions both across the country and around the world through research grants, career development awards, and other mechanisms. We support research grants and training awards to scientists across the nation.

Collaborations and Partnerships (Technology Transfer)

The NEI Technology Transfer Office facilitates collaborative relationships between NEI investigators and the broader scientific community.

Learn about our clinical trials

NEI leads or supports dozens of clinical trials and studies each year. Clinical studies can help researchers learn more about eye problems, while clinical trials help researchers try out new ways to test for and treat eye diseases. NEI studies have been instrumental in finding new ways to test and treat eye diseases.
