The Aging Eye Cohort Study

Study Overview
=================
Brief Summary
-----------------
Aging is a major risk factor for many blind-causing eye diseases, e.g., glaucoma, age-related cataracts, and age-related macular degeneration. With the population aging, the impact of lifestyle changes (less time spent outdoors, increasingly sedentary lifestyles, and unhealthy eating habits) on the eye health of the elderly needs further research. This study focuses on establishing a cohort of elderly subjects with normal vision and ocular structure at baseline. The main goal is to study the risk factors for common eye diseases in Chinese elderly population while providing normal-controlled clinical and genomic data for other clinical studies on eye diseases.
