Nutrition,
in particular, has been shown to have a much greater impact on eye
health than previously thought. Medical studies in the past few
years have linked lutein to the prevention of both eye and other health
disorders including cardiovascular disease and cancer. Lutein is a
naturally occurring carotenoid found in fruits and especially dark green
leafy vegetables. Essential for vision, lutein is the predominant
pigment in the macular area of the retina where it functions as a
powerful antioxidant and as a blocking agent for damaging ultraviolet
light. Studies using 6mg of lutein per day suggest a relationship
between lutein and the health of the eyes. Nutritional studies
show the average person consumes less than 1mg of lutein per day.
Since the human body does not produce or manufacture lutein, the
accumulation in the eyes is dependent on dietary intake.
Deficiency of lutein in the macular area has been implicated as a risk
factor for Age-Related Macular Degeneration. (AMD).
Lutein may be one of the most important discoveries in the prevention
and treatment of macular degeneration disease.
Clinical studies suggest a relationship between dietary supplements with lutein and the health of the macular area and the lens of the eye. While there are some factors which you have no control, such as age, heredity, and gender, you can control your lifestyle and diet. Dr. Johanna Seddon of Harvard University School of Medicine published a study examining the effects of consumption of specific carotenoids and the prevalence of Age-Related Macular Degeneration (AMD). The study found the highest correlation of disease prevention was associated with an intake of 6mg per day of lutein, which led to a 43% lower prevalence of AMD. In a similar study, Dr. Seddon found a 22% lower prevalence of cataract in women and a 19% lower prevalence of cataract in men who were consuming approximately 6mg of lutein per day. Early preventive
treatment will have a positive impact on functional vision in later
life. Age-Related Macular
Degeneration (AMD) is a slow progressive disease on setting early in
life and later leading to loss of vision and legal blindness.
Prevention is essential. There is no cure for AMD. There are
no prescription medications to cure or treat macular degeneration.
However, recent studies suggest supplements with lutein may be
helpful. There are no surgical procedures to restore functional
vision after it is damaged by "dry" macular
degeneration. Researchers are trying to find ways to prevent The Multicenter Opthalmic and Nutritional Age-Related Macular Degeneration Study reported several important positive conclusions and encouraged doctors to suggest use of dietary supplements for their patients. "AMD is the leading cause of legal blindness in people over the age of 50, and the prevalence of AMD is expected to increase as the population ages. Although the incidence of AMD increases sharply with age, recent studies of AMD that prevention measures and dietary changes can not only reduce the risk of developing AMD but also retard further deterioration in affected individuals." The study further stated: "Long before the patient has become aware of the disease, the macula has begun to deteriorate. Therefore, just as with cardiac disease, there is a large unmet need for a preventive medicine approach, in conjunction with early detection." study further concluded: "In conclusion, Age-Related Macular Degeneration (AMD) has been viewed as a hopeless disease. Yet the patients in this study has advanced atrophic AMD, with decreased acuity, which responded with stabilization to an antioxidant nutrient supplement formulation. This study is consistent with the hypothesis that AMD is a nutrition responsive disease." Dr. Max Snodderly of Schepens Eye Institute at Harvard University concluded that lutein blocks harmful ultraviolet light by absorbing the blue light and inhibiting photo-oxidation. Lutein also functions as a powerful antioxidant preventing destructive oxidation reactions by a mechanism known as free radical quenching. Researchers from Florida International University found increased serum levels and increased macular pigment density in subjects taking supplements with lutein. MG Maguire published a paper in Ophthalmology concluding that high levels of certain antioxidants and lutein in particular are protective against the neovascular or wet form of AMD. Dr. Gislin Dagnelie of John Hopkins University School of Medicine published a study examining the effects of lutein supplementation on visual acuity, central visual field area, and subjective visual disturbances in retinitis pigmentosa (RP) and related retinal degenerations. A 26 week study of lutein supplementation with a loading dose of 40mg/day for 9 weeks and 20 mg/day thereafter found: "Vision improvement after lutein supplementation - previously reported in age-related macular degeneration - also occurs in RP, especially in blue-eyed individuals." Studies suggest dietary supplements with lutein may be useful in AMD. However, to achieve positive results with lutein you must consume an appropriate amount. According to current studies the range is from 6mg/day for prevention and maintenance to 20-40mg/day for therapeutic use. MAXIVISION® products range from a basic eye vitamin with 6mg of lutein for prevention and maintenance to a comprehensive multivitamin with 20mg of lutein per dose.
