Objectives

Narrative objectives1

We will examine whether it is possible to detect amyloid deposits in the retina by administering curcumin to Alzheimer's disease patients and performing retinal amyloid imaging using a scanning laser ophthalmoscope. Retinal amyloid imaging will also be performed on non-Alzheimer's disease dementia patients and healthy controls, and the results will be compared with those of Alzheimer's disease patients to investigate the usefulness of retinal amyloid imaging in early detection of Alzheimer's disease.
we will investigate the influence of retinal amyloid deposition on visual function, detect the presence or absence of glaucoma in a target group of Alzheimer's disease patients, and investigate the relationship between retinal amyloid deposition and the onset of glaucoma.
