What this trial studies

This study aims to establish a cohort of elderly individuals with normal vision and ocular structure to investigate the risk factors for common eye diseases such as glaucoma and age-related macular degeneration. Participants will undergo yearly examinations for at least five years to collect clinical and genomic data. The focus is on understanding how lifestyle changes and genetics impact eye health in the aging Chinese population. The findings will provide valuable insights for future clinical studies on eye diseases.

Who should consider this trial

Good fit: Ideal candidates are elderly individuals over 60 years old with normal vision and no significant ocular diseases.

Not a fit: Patients with existing ocular diseases or those who have undergone recent eye surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better prevention and management strategies for eye diseases in the elderly.

How similar studies have performed: Other studies focusing on aging and eye health have shown promising results, indicating that this approach is supported by previous research.
