In the DM-MCI group, decreased GCL thickness and increased arteriolar thickness correlate with memory impairment. On the other hand, in the MCI group an increase in FAZ area and SCP show greater memory impairment, while an increase in arteriolar thickness correlates with greater executive function impairment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>DM and MCI influence the development of retinal damage that could predict the development of AD as they maintain correlation with the impairment of cognitive domains assessed by different neuropsychological tests.
