Objectives

Narrative objectives1

After oral administration of curcumin to glaucoma patients, retinal amyloid imaging using scanning laser ophthalmoscope is performed to examine whether the deposition of amyloid in the retina is different from that of healthy controls (cataract patients). We will also investigate the relationship between retinal amyloid deposition and cognitive function in glaucoma patients divided into three groups according to their degree of progression.
