Agreement was assessed for overall image quality and image quality relevant for vessel density (VD) quantification and foveal avascular zone (FAZ) metrics. An analytic framework was also developed.Intergrader agreements for overall 3 × 3 mm image quality and quantitative assessment of VD and FAZ ranged between $71\%$ and $87\%$ (52 images). Intragrader agreements ranged between $82\%$ and $93\%$ (n = 27 images). Intergrader agreements were similar for 6 × 6-mm images. Three analytic scenarios were developed to account for bias that may result from image quality and ocular comorbidities.These recommendations provide a framework for working with OCT-A imaging in epidemiological studies on ADRD.Multicentric consensus on quality criteria for use of optical coherence tomography angiography (OCT-A) images in population studies was achieved, considering commonly used protocols acquired with commercially available devices (Heidelberg, Zeiss, and Topcon). Considerable inter- and intrarater agreement was achieved for assessment of OCT-A image quality. A framework for harmonized data analyses was designed. Standardized analyses may accelerate the development of scalable retinal imaging biomarkers for ADRD.}, keywords = {Humans / Tomography, Optical Coherence: methods / Alzheimer Disease: diagnostic imaging / Retinal Vessels: diagnostic imaging / Reproducibility of Results / Fluorescein Angiography: methods / Female / Dementia: diagnostic imaging / Male / Aged / Alzheimer's disease and related dementias (Other) / accelerated cognitive ageing (Other) / epidemiology (Other) / harmonization (Other) / imaging (Other) / microvascular dysfunction (Other) / neurodegenerative disease (Other) / optical coherence tomography angiography (Other) / population‐based study (Other) / retinal imaging (Other)}, cin = {AG Breteler}, ddc = {610}, cid = {I:(DE-2719)1012001}, pnm = {354 - Disease Prevention and Healthy Aging (POF4-354)}, pid = {G:(DE-HGF)POF4-354}, experiment = {EXP:(DE-2719)Rhineland Study-20190321}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:40457754}, doi = {10.1002/alz.70252}, url = {https://pub.dzne.de/record/278997}, }
