abstract = {Widespread use of retinal optical coherence tomography
angiography (OCT-A) imaging requires methodological and
analytical consensus to ensure reproducible and accurate
results in epidemiological studies on Alzheimer's disease
and related dementias (ADRD).A consensus framework for
assessment of fovea-centered 3 × 3-mm and 6 × 6-mm OCT-A
image quality was developed, and reproducibility was
reported. 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.},
