Outline of Final Research Achievements

In this cross-sectional study of a community-based cohort, we found that circadian blood pressure variability was significantly diminished in elderly with cataracts and odds ratio (1.78) for carotid atherosclerosis was higher in the cataract group than that in the non-cataract group. These results indicated that decreased light reception by cataracts leaded to potential circadian misalignment. In the randomized study, urinary melatonin excretion 3 months after surgery was significantly higher in the cataract surgery group than in the control group. Cataract surgery may increase melatonin secretion.
Mobility functions indicated by walking speed and one-leg standing times were significantly associated with visual impairment in an elderly cohort. Thus, visual impairment may advance frail conditions in elderly.
We suggest the biological differences between pachychoroid neovasculopathy and age-related macular degeneration by genetic alternations in CFH and von Willebrand factor.

Academic Significance and Societal Importance of the Research Achievements

白内障は加齢に伴うほぼ必発の眼疾患であるが、白内障があると水晶体の混濁により視力が低下するだけでなく、血圧変動、頸動脈硬化の進行など全身的にも影響が大きいことを明らかにした。これは白内障により眼底へのブルーライトの到達が妨げられ概日リズムが変化したためと考えられる。
白内障手術によりメラトニン分泌が増加し、概日リズムが改善すると考えられ、視力の維持によりフレイルを予防でき、白内障手術が視機能の改善だけでなく、全身的に健康維持に働くということを明らかにした。
近年注目されるpachychoroid neovasculopathyと加齢黄斑変性の相違において初めて生物学的活性の違いを明らかにした。
