Definitions

  • This invention relates generally to methods and compositions for improving visual function and eye health and particularly to the use of combinations of lutein, zeaxanthin, beta-carotene, astaxanthin, vitamin C, and vitamin E for improving visual function and eye health.
  • Carotenoids are organic pigments that are naturally occurring in plants, algae and various microorganisms. Animals do not produce carotenoids therefore they must obtain them from their diet.
  • Lutein and Zeaxanthin are the two primary carotenoids found in the retina of the eye. The two compounds are isomers having identical chemical formulas. Zeaxanthin is the dominant component in the central macula and lutein is the dominant component in the peripheral retina. Lutein protects eyes from oxidative stress and the high-energy photons of blue light. Lutein and zeaxanthin can be derived from foods such as eggs, spinach, kale, turnip greens, romaine lettuce, broccoli and corn. Astaxanthin is a carotenoid with potent antioxidant properties. Astaxanthin can be found in sources such as microalgae, yeast, salmon, trout, krill, shrimp, and the feathers of some birds.
  • Beta-carotene is a red-orange pigment in many fruits and vegetables, such as carrots, mangoes, pumpkin, and sweet potatoes. Beta-carotene is a precursor to vitamin A. Vitamin C and vitamin E are essential nutrients for many animals. One of their many functions is to serves as antioxidants to lessen oxidative stress.
  • One or more of these or other objects are achieved by administering in conjunction to animals a visual function and/or eye health improving amount of two or more compounds selected from lutein, zeaxanthin, beta-carotene, astaxanthin, vitamin C, and vitamin E.
  • animal means a human or other animal that could benefit from an improvement in visual function or eye health, including avian, bovine, canine, equine, feline, hicrine, human, murine, ovine, and porcine animals.
  • the term "companion animal” means domesticated animals such as dogs, cats, birds, rabbits, guinea pigs, ferrets, hamsters, mice, gerbils, pleasure horses, cows, goats, sheep, donkeys, pigs, and more exotic species kept by humans for company, amusement, psychological support, extrovert display, and all of the other functions that humans need to share with animals of other species.
  • compositions suitable for consumptions by an animal including, but not limited to, dry food compositions, wet food compositions, and liquid food compositions.
  • the term "in conjunction” means that lutein, zeaxanthin, beta-carotene, astaxanthin, vitamin C, vitamin E, combination thereof, or other compound or composition of the present invention are administered to an animal (1) together in a food, dietary supplement, or other composition or (2) separately at the same or different frequency using the same or different administration routes at about the same time or periodically.
  • Periodically means that the compound or composition is administered on a dosage schedule acceptable for a specific compound or composition and that the food is fed to an animal routinely as appropriate for the particular animal.
  • “About the same time” generally means that the food and/or compound or composition is administered at the same time or within about 72 hours of each other.
  • ophthalmic agent means any compound or composition other than the compounds and compositions of the invention that are useful for improving visual function and eye health in animals.
  • dietary supplement means a product that is intended to be ingested in addition to a normal animal diet.
  • Dietary supplements may be in any form, e.g., solid, liquid, gel, tablet, capsule, powder, and the like. Preferably they are provided in convenient dosage forms, e.g., in sachets. Dietary supplements can be provided in bulk consumer packages such as bulk powders, liquids, gels, or oils. Similarly such supplements can be provided in bulk quantities to be included in other food items such as snacks, treats, supplement bars, beverages, and the like.
  • the term "regular basis” means at least monthly dosing with compounds or compositions of the present invention and more preferably weekly dosing. More frequent dosing or consumption, such as twice or three times weekly, is preferred in certain embodiments. Still more preferred are regimens that comprise at least once daily consumption, e.g., when compounds or compositions of the present invention are a component of a food composition that is consumed at least once daily.
  • single package means that the components of a kit are physically associated in or with one or more containers and considered a unit for manufacture, distribution, sale, or use.
  • Containers include, but are not limited to, bags, boxes, cartons, bottles, packages of any type or design or material, over-wrap, shrink-wrap, affixed components ⁇ e.g., stapled, adhered, or the like), or combinations thereof.
  • a single package may be containers of individual compounds or compositions of the present invention physically associated such that they are considered a unit for manufacture, distribution, sale, or use.

  • Eye Examination Ophthalmic evaluation was performed by a veterinary ophthalmologist via slit lamp biomicroscopy and indirect ophthalmoscope in both eyes of each dog. The dog's eyes were dilated with short-acting mydriatic eye drops, 1% tropicamide (Mydriacyl®), at least 15 minutes prior to examinations. Only dogs with a normal fundus appearance and without abnormalities of the eyes were included in the trial.

This is a mixture of vitamin and non vitamin antioxidants using cellulose as the mixing medium. The sachets are produced in the same batch, with 20 gram of powder per sachet, and 3 g of powder per dog per day was weighted by technicians to be topped on the wet food for every morning to the treatment group. The control group dogs received the same wet food but without sachets.
  • Dogs were fed two meals per day; one in the morning around 8-9 AM and one in the evening around 4-5 PM.
  • 2.75 oz of the Wet Control was fed to 6 dogs in a control group and 2.75 oz of the Wet Control topped with Test Food was fed to 6 dogs in the treatment group.
  • both treatment groups were offered the Dry Control for the remaining calorie ration of the meal.
  • Study Design All dogs were fed the Dry Control to maintain their body weight during an initial one- month baseline period. The body weight of each dog was monitored weekly. The body weight did not change more than 10% during the last three weeks of the baseline period.
  • Randomization After the baseline period, the dogs were randomized into two groups with 6 dogs per group based on their age, body weight, and gender. The groups were randomized to receive either Test Food or a control food composition. The results are shown in Table 4.
  • Feeding period (6 months): Dogs were fed to maintain their body weight. The body weight of each dog was monitored weekly and did not change more than 10% throughout the feeding study.
  • Electroretinography At the baseline and at the end of the 6-month period, a standardized ERG was performed in the dogs. Portable, mini-Ganzfeld ERG equipment was used with an automated and standardized canine ERG protocol in the dogs under deep sedation. This ERG protocol was performed by a veterinary ophthalmologist using the following procedures:
  • the dog's head was positioned on a deflatable cushion to ensure complete stability.
  • Maximum pupillary dilatation was provided for by the use of a short-acting mydriatic eye drop, 1% tropicamide (Mydriacyl), at least 15 minutes prior to the ERG procedure.
  • a lid speculum was inserted to ensure that the nictitating membrane and the upper and lower eyelids did not interfere with light exposure of the maximally dilated pupils.
  • a platinum subdermal needle electrode (Model E2; Grass Instrument Division, Astro-Med, Inc., West Warwick, RI) was used for the ground electrode, positioned on the occipital crest, and for the reference electrode, positioned 3 to 4 cm from the lateral canthus, close to the base of the right ear.
  • An active contact lens electrode (ERG-Jet; Universo Plastique, LKC Technologies Inc., Gaithersburg, MD) was placed on the cornea after instillation of one drop of 2% methylcellulose as a contact medium (Methocel ; Ciba Vision, Kunststoff, Germany). The electrodes were connected to a preamplifier, and the signals were amplified with a band-pass filter between 0.3 and 300 Hz.
  • Each ERG session consisted of scotopic and photopic ERGs in accordance with the Dog Diagnostic Protocol, recommended by the European College of Veterinary Ophthalmology, primarily for evaluation of rod and cone function. This protocol was preprogrammed on the ERG unit and was executed automatically on initiation of the ERG session by the examiner. During 20 minutes of dark adaptation, scotopic low- intensity of light stimuli responses were elicited at 0.01 cd-s/m2); averaged responses to 10 flashes, given at 2-second intervals, were recorded for each time point. The light stimulus intensity was then increased to 3 cd-s/m2 and the averaged responses to four flashes at 10-second intervals were recorded.
