Outline of Final Research Achievements

When a human sees things, an image is created on the retina and is transmitted by the optic nerve. The visual information is recognized by processing in the visual cortex of the brain (the cognitive function). Evaluation and inspection of the eye and optic nerve disease is possible, but evaluation of the cognitive function is not possible. We thought of the evaluating the cognitive function by the functional visual acuity (FVA).
FVA is the average of the continuous visual acuity for one minute. It is considered to represent the visual acuity used for daily activities, and it is now known that the FVA is influenced by many factors. In this study, we investigated the association of FVA and the cognitive status test; Mini Mental State Examination (MMSE) in patients after cataract surgery. Our results showed that FVA and MMSE are statistically correlated, and there is a possibility to evaluate the cognitive function using FVA.
