Most studies considered only basic visual functions such as visual acuity or visual field size and evaluated the association with dementia. Objectives: To reconcile between these theories and to test the link between visual and cognitive decline in mildly cognitive impaired people. Methods: We employed a battery of 19 visual tasks on 39 older adults with mild cognitive impairment and 91 without any evidence of cognitive decline, as measured by the Montreal Cognitive Assessment. Results: Our results show a strong association between visual impairment and mild cognitive impairment. In agreement with previous results with younger and healthy older adults, we found also only weak correlations between most tests in older adults with mild cognitive impairment. Conclusion: Our results suggest that visual and cognitive abilities decline simultaneously, but they do so independently across visual and cognitive functions and across participants.
