Impact of macular pigment optical density on photophobia threshold
… where they are collectively referred to as macular pigment (MP). By absorbing short-wavelength light, MP may attenuate photophobia (PP)---visual discomfort induced by normal light exposure---for targets composed of short-wavelength light. The aim of this study was twofold: first, to …

Macular pigment optical density and academic achievement among preadolescent children
… accumulate in the macula of the neural retina as macular pigment and across all brain cortices of infants and adults. This preferential accumulation in the brain has led to the hypothesis that lutein may positively impact cognition, possibly through its anti-inflammatory and/or antioxidant …

Investigating determinants of macular pigment optical density and macular pigment distribution in adults aged 45--73: Can enhanced analytical techniques improve the ability to predict macular pigment status?
… of dietary, sex, and biochemical factors to macular pigment optical density (MPOD) and macular pigment (MP) distribution in 108 adults. Dietary assessment tools were evaluated for their ability to predict MP status. Macular pigment was assessed at four foveal sites and one parafoveal site. An …

DOSE RANGING STUDY OF LUTEIN SUPPLEMENTATION IN ELDERLY WITH AND WITHOUT AGE RELATED MACULAR DEGENERATION
Age-related macular degeneration (AMD) is the leading cause of blindness among people over the age of 65. Epidemiological studies have indicated that people with a high intake of two dietary carotenoids, lutein and zeaxanthin that accumulate in the human macula, are at a reduced risk of AMD. …

The impact of lifestyle factors and development on relational memory
… of aerobic fitness, body composition, and macular pigment optical density (MPOD) in predicting relational memory performance during childhood. Chapter three expands the investigation of hippocampal-dependent cognition beyond relational memory to include mnemonic discrimination and evaluates …

Chromatic sensitivity: effects of light level and selective photoreceptor adaptation
… to correlate with the central 2.8° mean value of macular pigment optical density, hence providing a new method of estimating macular pigment level from colour detection ellipses. Steady state pupil sizes were analysed with the rod and cone excitations that produced them. These data indicate that …

INTERRELATIONSHIPS BETWEEN MACULAR CAROTENOIDS, RETINAL MORPHOMETRY, AND COGNITIVE FUNCTION IN PERSONS WITH MULTIPLE SCLEROSIS
… regular dietary consumption to derive benefits. Macular xanthophylls are dietary carotenoids that comprise the macular pigment, serving as blue light filters and countering photooxidative damage. The robust antioxidant effects of carotenoids could support nerve health and protect against …

Early life nutrition and genetic contributors to carotenoid status in children
… understand the inter-individual variability of macular pigment in children, as this is a critical time for visual and cognitive development Objectives. The objectives of the thesis were to: 1) investigate the association between early life nutrition (i.e. breastfeeding exclusivity and duration) …
