Since its inception in October 2010 Collaborative Network Research Study at the Wills Eye Institute has aimed: 1. to establish a retrospective analysis of existing ophthalmic data sets to assess and evaluate system-level and individual-level factors that impact access to and quality of vision care in patients with diabetes; 2. to implement telephone-based and educational interventions to improve DFE follow-up adherence in African Americans with diabetes utilizing a prospective, cluster-based, randomized cohort design; 3. to determine the feasibility and effectiveness of using a non-invasive, non-mydriatic fundus camera (Nidek) in a community-based pharmacy setting to screen and detect diabetic retinopathy and other ocular diseases among individuals with diabetes.
