Results obtained by one-way ANOVA test. ATD: Alzheimer’s type disease; MCI: mild cognitive impairment; SD: standard deviation, C: central field; SI: superior internal field; TI: temporal internal field; II: inferior internal field; NI: nasal internal field; SE: superior external field; TE: temporal external field; IE: inferior external field; and NE: nasal external field.
value represents comparison among the three groups.
