The National Eye Institute's (NEI) budget for fiscal year 2016 was $695 million, which was used to fund research projects, training, clinical trials, and small business innovation grants. Major initiatives included regenerating neurons and neural connections in the eye through the Audacious Goals Initiative, contributions to the BRAIN Initiative and Precision Medicine Initiative. The NEI supports collaborative research projects, small business grants, and conducts intramural research including stem cell therapy and gene therapy clinical trials. Growing the vision research field through training and diversity programs is also a priority.
