Fig. 5From: Retinal mid-peripheral capillary free zones are enlarged in cognitively unimpaired older adults at high risk for Alzheimer’s diseaseScatter plot showing the individual variations in the mid-peripheral CFZs in low- and high-risk cognitively unimpaired (CU) older adults. a Scatter plot of the periarteriole CFZ width versus age showing individual variations in the periarteriole CFZs in low- and high-risk CU older adults. A trend towards large periarteriole CFZs can be observed for the high-risk CU older adults. b Scatter plot of perivenule CFZ width versus age showing individual variations in the perivenule CFZs in low- and high-risk CU older adults. A trend towards large perivenule CFZs can be observed for the high-risk CU older adultsBack to article page
