Singapore Epidemiology of Eye Diseases Study (SEED)
The SEED study is a multi-ethnic longitudinal population-based study that evaluates the incidence, prevalence, risk factors, and novel biomarkers of age-related eye diseases for Singaporean adults of Malay, Indian, and Chinese descent. The SEED cohort is based on an age-stratified random sampling strategy of individuals above the age of 40 years from 15 residential districts in the South-Western part of Singapore. A total of just over 10,000 Singaporean adults participated in the baseline SEED examination. The mean age of all baseline participants was 58.9 years, and had almost equal distributions of participants between all three ethnic groups (3,280 Malays, 3,400 Indians, and 3,353 Chinese). There has been a 6-year follow-up (SEED-2) and a 12-year follow-up (SEED-3).
