The goal of this observational study is to learn about the interaction between the eyes, brain, and kidneys in adult patients with Chronic Kidney Disease (CKD). The main question it aims to answer is:
Do changes in the brain's network connectivity and the retina's blood vessels correlate with cognitive decline and kidney function in CKD patients? Participants with CKD who are already undergoing clinical care will complete cognitive tests and questionnaires, have non-invasive MRI scans of their brain and kidneys, and undergo non-invasive eye imaging (OCT/OCTA) of their retinas.

Primary outcome measure(s)
Cognitive function assessed by Montreal Cognitive Assessment (MoCA) — Baseline and 3-year follow-up. The Montreal Cognitive Assessment (MoCA) is a cognitive screening tool with a total score range of 0 to 30, where higher scores indicate better cognitive function. A score below 26 is indicative of cognitive impairment.
