Abstract:
A novel method of assessing visual performance is provided, which can simulate the effect of pigment absorption on visual acuity and indicate macular pigment optical density (MPOD). The method can simulate the amounts of pigment in the eye and assess e.g. the response of the eye, (or the reaction of an individual) to different levels of blue light. The individual can be asked to detect a specific feature (a gap in Landolt rings) at decreasing contrast levels, the Landolt rings (and background) both being blue. This can provide an indication of the density or concentration of levels of macular pigments in an individual's eye which can help determine treatments or substances to be administered (carotenoids, such as lutein or zeaxanthin) to improve the individual's visual performance.
Abstract:
A method of prevention of age-related macular degeneration (AMD) is provided where a sample is taken from an individual and the presence of a polymorphism associated with a dehydrogenase, oxygenase, acyltransferase, dismutase or a macular or retinal pigment, or an SNP as shown in Table 1 of the specification, is detected. The individual can then be provided with a substance that can prevent or treat AMD, or can mitigate or alleviate symptoms of AMD. The substance is a medication comprising lutein and/or zeaxanthin and/or certain antioxidants (or a mixture thereof) is tailored to that individual.
Abstract:
A method of prevention of age-related macular degeneration (AMD) involves, in a first step, taking a sample from an individual and detecting the presence of a polymorphism (rsl 1200638 or rs 10490924, or an SNP related to or associated with a (high temperature requirement) serine protease). In a second step the individual is provided with a substance that can prevent AMD, or can mitigate or alleviate symptoms of AMD. The substance is a medication comprising lutein and/or zeaxanthin and/or certain antioxidants (or a mixture thereof) is tailored to that individual. The invention also provides a method of determining the substance to be administered to an individual, which individual may be susceptible of having age-related macular degeneration (or an age-related macular degeneration-related disorder) by detecting the presence of the polymorphism and identifying a substance capable of preventing or treating age-related macular degeneration in that individual. The method may additionally comprise providing (such as administering or communicating) the substance (or its identity) to the individual.
Abstract:
Use of specific carotenoids in dye sensitized solar cells. Preferred carotenoids according to the present invention are listed in the following : Bixin (A), Canthaxanthin (B), Astaxanthin (C), Zeaxanthin (D), Torularhodin (E).
Abstract:
The present invention is directed to the use of (a composition comprising) hydroxytyrosol for treating or preventing age-related macular degeneration in humans, for maintaining the eye health in animals (preferably in humans), especially in elderly animals (preferably elderly humans), for improving the vision of animals (preferably of humans), for maintaining the high resolution vision in animals (preferably in humans) and/or for maintaining the visual acuity in animals (preferably in humans), as well as for maintaining the visual performance in animals (preferably in humans) and/or the visual function in animals (preferably in humans).

Abstract:
The invention relates to the improvement of visual performance, particularly of visual performance in the darkness, by administration of a colorant that is capable of being incorporated into eye tissue and/or causing yellowing of eye tissue, especially carotenoids, such as lutein and zeaxanthin.
