Abstract: Macular pigments refers to lutein, zeaxanthin, and meso-zeaxanthin that are concentrated in macula lutea. They all belong to xanthophyll which is a subclass of carotenoid. These pigments are closely associated with eye diseases, particularly age-related macular degeneration, as well as fundus imaging. Currently, it is widely believed that dietary intake or supplementation of these three xanthophylls may benefit eye health and visual function. This article systematically sorts out the sources, chemical structures, distribution within the body, transport and uptake mechanisms, spectral characteristics, clinical detection methods, functions, and clinical significance of macular pigment, aiming to raise attention to macular pigment and related researches.

Key words:  Macular pigment, Fundus imaging, Medicated diet, Eye health
