This study establishes a clinical database and biospecimen repository for identification of novel factors relevant to the pathogenesis, progression, and response to treatment of a variety of retinal conditions, particularly age-related macular degeneration and diabetic retinopathy, and their associated systemic correlates of disease. Objectives: This study provides for standardized collection of longitudinal clinical data and for serial collection, processing, and storage of a variety of biospecimens. The clinical data set and biospecimen repository will be used for identification of novel genetic factors, biomarkers, and experimental models associated with pathogenesis, progression, and response to treatment for various conditions of the retina and their associated systemic correlates of disease. Study Population: We plan accrual of 500 participants with age-related macular degeneration (AMD), 300 participants with diabetic retinopathy, up to 1,000 participants with other retinal diseases, and 500 participants without any retinal disease. Design: This is a prospective observational study of multiple retinal diseases and suitable controls incorporating: 1. Standard of care management of eye diseases with a standardized follow-up and testing schedule;and 2. Collection of biospecimens for research purposes for which sampling does not incur more than minimal risk to participants. Outcome Measures: Interaction of key parameters of phenotype (such as visual acuity and retinal features on ocular imaging) with genetic variants and other biomarkers identified from biospecimens;and characterization of new experimental models of eye health and disease. In fiscal year 2014, we expanded capacity of our biorepository for DNA specimens and instituted a new set of sample processing and storage procedures in anticipation of expanding beyond the pilot phase of the protocol. This has allowed for acceleration of recruitment for the study.
