    Abstract: A method of identifying a human subject, more likely than a subject selected at random from the general population, to have one or more of the following: (i) a low macular pigment concentration in the eye or eyes; (ii) a low visual performance, or (iii) an atypical "central dip" macular pigment distribution; the method comprising the steps of: measuring at least one cognitive function of the subject; comparing the measured cognitive function with a pre-determined threshold; and, if the measured cognitive function is below the threshold, declaring the subject as being more likely to have one or more of low macular pigment concentration in the eye or eyes, low visual performance or an atypical "central dip" macular pigment profile.

    Abstract: A composition comprising xanthophyll carotenoid mesozeaxanthin (MZ) for use as a dietary supplement or food additive for oral consumption for improving the visual performance of a human subject, in particular, a human subject not experiencing age-related macular degeneration (AMD). Visual performance may be assessed by measuring one or more of spatial contrast sensitivity function, (best corrected) visual acuity, glare disability, discomfort glare, ocular straylight, photostress recovery and S-cone sensitivity. The composition may also comprise lutein and/or zeaxanthin. A preferred combination is MZ/lutein/zeaxanthin in the ratio 10:10:2. Additional components may include one or more vitamins and/or minerals; a vegetable oil, fish oil and/or omega 3 fatty acid. The composition may be in the form of an egg obtained from a hen fed with a feed comprising MZ. A method of preparing the composition comprising the step of mixing an effective amount of MZ with an acceptable dietary diluent, excipient or carrier is also claimed.
