Relationship between inner nasal macular thickness and FBB-PET. Inner nasal macular thickness differences according to the participants’ FBB-PET status (+/−) at v0 (a) and at v2 (b). Correlation between inner macular thickness and FBB global SUVR at v0 (c) and at v2 (d). Both inner nasal macular thickness and FBB global SUVR are expressed as standardized scores after adjustment by age, gender, education, APOE ε4 status and OCT image quality. Abbreviations: APOE apolipoprotein E, FBB Flobetaben, PET positron emission tomography, SUVR standardized uptake value ratio, v0 baseline visit, v2 2-year follow-up visit
