| Outline of Final Research Achievements |
In the study using laser speckle fluorography, it has been found that ocular blood flow has a diurnal variation in the optic nerve head and the choroid, and the optic nerve head has a strong autoregulation for maintaining the blood flow to the retina constant. I have found sex-related difference in ocular blood flow, especially at the optic nerve head and female has higher blood flow than male. I have succeeded in visualizing the blood flow velocity state in the retinal blood vessels and found that the blood flow state differs between arteries and veins of retinal blood vessels. I has been found that choroidal luminal area and age are significantly correlated with choroidal blood flow. It has bee elucidated that retinal blood flow is reduced before surgery in eyes with rhegmatogenous retinal detachment and it can be increase following retinal re-attachment.
