Design: A cross-sectional study. Methods: Three hundred twenty-six individuals from the PATH Through Life project were invited to participate. Participants completed a general questionnaire and 2-field, 45-degree nonmydriatic color digital retinal photography. Photographs were graded for retinal pathology according to established protocols. Results: Two hundred fifty-four (77.9%) subjects, aged 72 to 78 years, agreed to participate in the eye substudy. Gradable images of at least 1 eye were acquired in 211 of 254 subjects (83.1%). Retinal photographic screening identified 1 or more signs of pathology in 130 of the 174 subjects (74.7%) with gradable images of both eyes. A total of 45 participants (17.7%) had self-reported diabetes and diabetic retinopathy was observed in 22 (48.9%) of these participants. Conclusions: This well-defined sample of older Australians provides a unique opportunity to interrogate associations between retinal findings, including retinal vascular geometric parameters, and indices of neurocognitive function.application/pdfen-AU201710.22608/aPO.20161872020-11-23
