Eligibility Criteria:
Inclusion Criteria:
* Male and female adults aged 50 years and older with vision in both eyes.
* Sufficient fluency in English or French to participate in study visits.
* Ability to give informed consent.
* Individuals with both eyes meet the eligibility criteria for retinal imaging.
Exclusion Criteria:
* Pupil dilation contraindicated (due to pathology, or presence of 3 quadrants with Van Herick grading of 0 or 1 without iridotomy).
* Inadequate pupil dilatation (\< 6mm diameter) preventing uniform illumination of the retina with the Optina 4CTM camera.
* Diagnosis of glaucoma or signs of glaucoma (excavation ratio ≥0.7).
* Signs of vascular occlusion or retinopathy (microaneurysm, exudate, hemorrhage, or edema) within a diameter of 10 mm from the mid-point between the optic nerve head and the macula.
* Presence of drusen and/or age-related macular degeneration (AREDS 9-step scale
≥4 - cumulative drusen area diameter ≥ 250 µm, pigmentary changes and cumulative drusen area diameter ≥ 63 µm or pigmentary changes and cumulative geographic atrophy area diameter ≥ 354 µm).
* Nuclear sclerosis \> 2 (LOCS II four-point grading system) or presence of central cortical or central posterior subcapsular cataract.
* Deficient visual fixation (inability to fixate for at least 2 s).
* Refractive error outside the range of -15 D to +15 D.
* Corneal or media opacities (e.g., Weiss ring) affecting retinal imaging on a cumulative area \> 1 disc area within a diameter of 10 mm from the mid-point between the optic nerve head and the macula (i.e., the area of interest for the Optina 4CTM imaging)
* Scar, atrophy, naevus, tumor, epiretinal membrane or retinal pucker with a cumulative area \> 1 disc area within a diameter of 10 mm from the mid-point between the optic nerve head and the macula.
* Papilledema and/or optic disc swelling.
* Macular anomaly (e.g., macular hole, dystrophy, degeneration).
* Inability to obtain up to 5 images or a minimum of 3 images of satisfactory quality with the Optina 4CTM per the Optina Diagnostics quality index software and /or per the eye specialists' evaluation. This exclusion criterion also applies if participants are unable to provide the required number of images during the second visit as well.
* Currently taking or has previously taken cerebral amyloid modifying medication.
