225-578-4161 Professor Cristina Sabliov, left, and assistant professor Carlos Astete, of the LSU AgCenter Department of Biological and Agricultural Engineering, have formulated a nanoparticle matrix that could be used in eye drops to both prevent and treat cataracts. Kuzniarz M, Mitchell P, Cumming RG, Flood VM. Because of the missing information on all subtypes, we used a clinically important outcome, cataract surgery, as our primary outcome. A cataract is a clouding of the lens in the eye that blurs vision, changes the way you see colors (they seem faded) and generally reduces visual acuity. Long-term supplementation with alpha-tocopherol and beta-carotene and age-related cataract, A randomized trial of beta carotene and age-related cataract in US physicians, The Linxian cataract studies: two nutrition intervention trials. out of DrWeil.com subscriptions at any time. Whether supplementation would be beneficial for less well-nourished populations requires further study. A total of 3159 AREDS2 participants were phakic in at least 1 eye and 1389 of 6027 study eyes underwent cataract surgery during the study, with median follow-up of 4.7 years. Seddon JM, Christen WG, Manson JE, et al. This study was supported by the intramural program funds and contracts from the National Eye Institute/National Institutes of Health, the Department of Health and Human Services, Bethesda, MD (contract No. AREDS2 volunteers were generally better educated and better nourished than the general population, with higher dietary intake levels of lutein/zeaxanthin and omega-3 LCPUFAs. It can be found in numerous plants, including yellow flowers and corn, as well as egg yolks and animal fats. In subgroup analyses restricted to quintiles of dietary lutein/zeaxanthin intake, HRs for the first and fifth quintiles were 0.70 (95% CI, 0.530.94; P = .02) and 1.15 (95% CI, 0.861.54; P = .36), respectively, for the lutein/zeaxanthin vs no lutein/zeaxanthin comparison (Figure 4). A rationale for examining the impact of lutein/zeaxanthin comes from observational data collected in AREDS, other epidemiologic studies, and animal studies.19 Lutein and zeaxanthin, xanthophylls with antioxidant capabilities, are the only carotenoids detected in the human lens.20 Observational studies have demonstrated an inverse association between dietary intake and/or blood levels of lutein/zeaxanthin and the progression of cataract, particularly the nuclear form and cataract surgery.2124 AREDS2 provided an opportunity to examine the effect that daily dietary supplementation with lutein/zeaxanthin had on age-related cataracts in a randomized clinical trial. Abbreviations: AREDS2, Age-Related Eye Disease Study 2; DHA, docosahexaenoic acid; EPA, eicosapentaenoic acid; IQR, interquartile range. Terms and Conditions AREDS2 was designed to test large doses of lutein/zeaxanthin, 10mg/2mg, against near dietary levels of intake. Although not statistically significant, mean percentage increase in serum levels of lutein/zeaxanthin in those randomized to lutein/zeaxanthin and beta carotene were lower than those randomized to lutein/zeaxanthin alone at year 5 (171% vs 270%, respectively; P = .08). Dietary lutein/zeaxanthin, g/d/1000 kcal. The nanoparticle matrix can deliver lutein to the eye efficiently as an eye drop formulation, Sabliov said. Vitamin supplementation in a relatively undernourished population in China reduced the risk for progression of lens opacities.13 Whether there is a subgroup of persons who are relatively less well nourished that would benefit from lutein/zeaxanthin supplementation to slow the progression of lens opacities remains uncertain. The severity and progression of cortical and PSC opacities on the red reflex lens photographs and the presence of pseudophakia or aphakia were graded at the reading center. Other outcomes included (1) progression to cataract surgery or an absolute increase in opacity size (area) within the central 5 mm of the lens or 10% for cortical or 5% for PSC opacities; (2) progression to cataract surgery or a 20% absolute increase in the area of either opacity within the central 5 mm of the lens; and (3) a reduction in visual acuity of 15 or more letters from baseline. A test of interaction between treatment and the quintile groups had a P value of .003. Institutional review boards at the clinical sites approved the AREDS2 research protocol, and participants provided written informed consent. HHS-N-2602005-00007-C and ADB contract No. They could not have other ocular diseases that might confound assessment of the ocular outcomes or other systemic diseases including lung cancer or other diseases associated with poor 5-year survival. Certified photographers obtained red reflex lens photographs at baseline and annually. Of the 3159 randomized participants, 104 (3%) were lost to follow-up and 204 (6%) died. Median baseline serum levels of lutein in participants randomized to lutein increased by 191% to 215% at years 1, 3, and 5, while those randomized to placebo showed minimal changes.

AREDS2 was conducted at 82 retinal specialty clinics and the primary focus was on the retinal outcomes. National Library of Medicine Exclusive Lifestyle, Nutrition & Health Advice. The reduction in the serum levels of lutein/zeaxanthin in those participants who received both carotenoids may be the result of the apparent systemic competitive absorption of carotenoids. significant scientific evidence that suggests, Lutein and zeaxanthin function as blue light filters, and, as such, can help reduce the risk of cataracts, American Optometric Association (AOA): Diet and nutrition, All About Vision: Lutein and zeaxanthin: Eye and vision benefits. Age-related cataract is a leading cause of visual impairment in the United States. Of the 6027 eligible eyes, 1504 (25%) had an outcome defined as severe cataract. This includes the Age-Related Eye Disease Study (AREDS), which tested a formulation containing vitamin C, 500 mg; vitamin E, 400 IU; and beta carotene, 15 mg; as well as the minerals zinc (as zinc oxide), 80 mg, and copper (as cupric oxide), 2 mg, for both age-related macular degeneration (AMD) and cataract.18 Although AREDS showed a 25% beneficial effect for reducing the risk for developing advanced AMD, it showed no statistically significant effect of the AREDS formulation on the progression of lens opacities. Resnikoff S, Pascolini D, Etyaale D, et al. Annual best-corrected visual acuity testing was performed. For lutein/zeaxanthin vs no lutein/zeaxanthin, the hazard ratios for progression to cataract surgery was 0.96 (95% CI, 0.841.10; P = .54). 2022 content kindly provided by SpaMedica. Participants and study personnel were masked to all treatment assignments. Christen WG, Liu S, Glynn RJ, Gaziano JM, Buring JE. Assessing nuclear opacities requires specialized slit-lamp photography, which was not readily available in a retinal practice, so that information on nuclear cataract was incomplete. The 5-year probability of progression to cataract surgery in the no lutein/zeaxanthin group was 24%. Although the optimal approach to assessing the lens outcome, using specialized lens photography, was beyond the scope possible for AREDS2 whose investigators were all retinal specialists without such equipment, we were able to incorporate red reflex lens photographs for grading the severity of cortical and PSC lens opacities. Cataracts usually are age-related and represent accumulated free-radical damage to the protein molecules that form the lens of the eye. Flow Diagram of Participants in the Age-Related Eye Disease Study 2 of Lutein/Zeaxanthin Treatment for Age-Related Cataract. Perhaps the intervention was too late or of insufficient duration to affect the outcomes. Approximately 80% of the participants took the study medications at least 75% of the time, as assessed by pill count. Given the advanced age of participants, cataracts may have already begun to develop in many who had no apparent opacities at the start of the study.

The new PMC design is here! The study examined the effects of lutein/zeaxanthin on progression to cataract surgery with data collected during regular telephone contacts and the annual study visits. Comparison of omega-3 LCPUFAs vs no omega-3 LCPUFAs resulted in a nonstatistically significant HR of 1.01 (95% CI, 0.881.15; P = .93). Duplicate gradings of the red reflex lens photographs demonstrated 93% agreement for the presence of cortical opacities and 97% agreement for the presence of PSC. While observational studies have suggested that higher dietary intake or higher blood levels of lutein and zeaxanthin may have a protective effect on the development of cataract, this randomized, placebo-controlled trial did not find an effect of supplementation with lutein/zeaxanthin on cataract surgery, cortical or PSC lens opacity progression, or vision loss. The mean age of AREDS2 participants at enrollment into the follow-up study was 72 years. Funds were contributed to these contracts by the following National Institutes of Health institutes: Office of Dietary Supplements; National Center for Complementary and Alternative Medicine; National Institute on Aging; National Heart, Lung and Blood Institute; and National Institute of Neurological Disorders and Stroke. None of the nutrients studied affected rates of moderate or worse vision loss, defined as a loss of 15 or more letters from baseline. At baseline, 2878 participants were bilaterally phakic, while 281were pseudophakicin1 eye. The World Health Organization estimates the condition is responsible for almost 50 percent of blindness worldwide. Best-corrected visual acuity was obtained annually using a standardized protocol. A secondary outcome of AREDS2 was to evaluate the effects of lutein/zeaxanthin on the subsequent need for cataract surgery. and transmitted securely. Baton Rouge, LA 70803 About half of the AREDS2 cohort who consented to the secondary study randomization were assigned to take high doses of beta carotene and the other half to no beta carotene. 2002 global update of available data on visual impairment: a compilation of population-based prevalence studies. Privacy Policy. NAC is available in this country, but no claims can be made for its effectiveness, so it is listed as an inactive ingredient. The number of eyes and Kaplan-Meier probabilities (N[%]) of progression to cataract surgery by 5 years for study eyes randomized to lutein/zeaxanthin or no lutein/zeaxanthin were 681 eyes (24%) and 708 eyes (24%), respectively (Figure 2). Dr. Weil's FREE health living advice delivered to you! Congdon N, Vingerling JR, Klein BE, et al. Baseline dietary intake of the study nutrients, excluding the supplements, such as Centrum Silver, was balanced across treatment groups. Nearly all of the remaining participants (98.2%) chose to take the commercial AREDS formulation (Figure 1). FOIA The primary outcome, cataract surgery, is a clinically important and an easily verified outcome. The primary outcome of the cataract clinical trial was progression to cataract surgery. AREDS2 enrolled 4203 people with a mean (SD) age of 73.1 (7.7) years. There were more than 24 million cases of cataracts in the U.S. in 2010, according to the National Eye Institute. Additional analyses and subgroup analyses were analyzed in the same fashion as the primary lens efficacy outcome. Results for quintiles 2 through 4, also displayed in Figure 4, were greater than quintile 1 and less than quintile 5. Causes and prevalence of visual impairment among adults in the United States. Follow-up study visits were conducted annually. Photo by Olivia McClure/LSU AgCenter, The LSU AgCenter and the LSU College of Agriculture, 101 Efferson Hall Oral supplementation daily with lutein/zeaxanthin, DHA/EPA, or the modifications of the AREDS formulation had no effect on mortality. The median follow-up duration was 4.7 years (inter-quartile range, 4.45.1 years). Vu HT, Robman L, Hodge A, McCarty CA, Taylor HR. The HR for the development of moderate vision loss was 1.03 (95% CI, 0.931.13; P = .59; Figure 3) for the lutein/zeaxanthin vs no lutein/zeaxanthin comparison. A study ophthalmologist examined the anterior segment using slitlamp biomicroscopy at the annual visit to diagnose or confirm the presence of pseudophakia or aphakia. Lutein and zeaxanthin function as blue light filters, and, as such, can help reduce the risk of cataracts(2). The For participants in the lowest quintile of dietary intake of lutein/zeaxanthin, the hazard ratio comparing lutein/zeaxanthin vs no lutein/zeaxanthin for progression to cataract surgery was 0.68 (95% CI, 0.480.96; P = .03). Everything you need to get started eating a healthful, satisfying diet is here including eating and shopping guides, over 300 recipes, and an exclusive version of Dr. Weils Anti-Inflammatory Food Pyramid! To determine whether daily oral supplementation with lutein/zeaxanthin affects the risk for cataract surgery. Studies have shown that dietary supplements can help replenish ocular lutein. Details of the AREDS2 study design described in a previous report25 are briefly summarized here. Dr. Weil on Healthy Aging - Your Online Guide to the Anti-Inflammatory Diet! Lutein is a naturally occurring yellow pigment known as a carotenoid. or Healthy Lifestyle Brands. Federal government websites often end in .gov or .mil. Baseline Characteristics of Participants Enrolled in AREDS2 Cataract Study. Moeller SM, Voland R, Tinker L, et al. Bilateral pseudophakia was present in 1044 participants who were excluded from the cataract analyses, leaving 6027 study eyes (3159 participants). ; Eye Diseases Prevalence Research Group. There is significant scientific evidence that suggests(1) that lutein helps to stave off cataracts. Progression to Cataract Surgery in Age-Related Eye Disease Study 2 Participants by Treatment (Lutein/Zeaxanthin vs No Lutein/Zeaxanthin), Effect of Lutein/Zeaxanthin Supplementation on the Progression of Cataract Stratified by Dietary Intake of Lutein/Zeaxanthin, Effect of Lutein/Zeaxanthin Supplementation on Moderate Vision Loss (3 or More Lines) From Baseline Stratified by Dietary Intake of Lutein/Zeaxanthin. All rights reserved. By clicking "Subscribe," you agree to the DrWeil.com Distributions were similar across the 4 treatment groups. The site is secure. Of these, 777 eyes were phakic. Cataracts are a common condition in older adults that causes the lens of the eye to become cloudy and block light from the retina. AREDS2 participants in the lowest quintile of dietary intake of lutein/zeaxanthin showed some evidence of a beneficial effect of lutein/zeaxanthin supplementation on the progression to the cataract outcomes. LSU AgCenter scientists have formulated a nanoparticle matrix that could be used in eye drops to both prevent and treat cataracts, a leading cause of vision loss in older adults. *AREDS2 Research Group Writing Team: The members of the writing team and their affiliations are found at the end of this article. The procedure is very safe, effective, and quick. The Age-Related Eye Disease Study 2 (AREDS2), a multicenter, double-masked clinical trial, enrolled 4203 participants, aged 50 to 85 years, at risk for progression to advanced age-related macular degeneration. No clinically or statistically significant serious adverse effect was associated with the treatments. Patients lost to follow-up or who died during the course of the study were censored at the time of the last contact. 21, Carotenoid bioavailability and bioconversion, Intestinal absorption, serum clearance, and interactions between lutein and beta-carotene when administered to human adults in separate or combined oral doses. In addition to lutein and zeaxanthin, vitamins C and E, glutathione, polyphenols, omega-3, manganese and zinc have all been linked to improved eye health, as well. The possible effect of competitive absorption of carotenoids, which has been demonstrated in other human studies31,32 and in animal studies,33 also needs consideration. A run-in phase using study placebo and the AREDS formulation tested the participants likely ability to adhere to the study regimen. Direct application of lutein to the eye in this formulation improves its effect against cataracts.. The effect of Centrum use on our results cannot be determined because nearly all participants took the supplement. The prevalence of age-related cataract is increasing, with an estimated 30.1 million Americans likely to be affected by 2020. N-acetylcarnosine, a dipeptide found in muscle and nerve cells, can help maintain protein integrity in the lens and is being studied in eye drop form for treatment of cataracts. The https:// ensures that you are connecting to the DHA indicates docosahexaenoic acid; EPA, eicosapentaenoic acid. An official website of the United States government. Baseline cataract status was comparable across the 4 treatment groups. A second randomization was conducted for the AMD component of the trial. Masked duplicate photographic gradings were conducted every month on 5% of eyes randomly selected from the previous months evaluations, resulting in 1293 eyes that had repeat gradings between 2009 and 2012. You can get sulfur from onions, garlic, shallots and capers and can boost your intake with supplements of alpha-lipoic acid (ALA) (250 mg twice a day) and N-acetylcysteine (600 mg twice a day). Participants were eligible for enrollment at their randomization visit if they took at least 75% of the run-in medications and if they agreed to take the AREDS2 supplements and stop current use of supplements containing lutein, zeaxanthin, docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), vitamin C, vitamin E, beta carotene, zinc, or copper, unless supplied by AREDS2. The photographs were assessed by masked graders for the severity of cortical and posterior subcapsular cataract (PSC) lens opacities at the University of Wisconsin Fundus Photograph Reading Center, Madison, Wisconsin. about navigating our updated article layout. The lutein eye drops could offer an effective, non-surgical and more accessible treatment option. Although there was no scientific rationale to consider omega-3 LCPUFAs to be important in reducing the progression to cataract surgery, this analysis was conducted for completeness. 2013 Jul; 131(7): 843850. The adherence data are further supported by data showing that serum levels of nutrients were elevated throughout the study, on average, in participants assigned to the medications. Good sources are kale, spinach, collard greens, other leafy greens and eggs (choose organic eggs fortified with omega-3 fatty acid, which contains DHA, another nutrient that is good for the eyes).

A comparison of lutein/zeaxanthin to no lutein/zeaxanthin for progression to cataract surgery resulted in a HR of 0.96 (95% CI, 0.841.10; P = .54) (Figure 3). Dietary modulation of lens zeaxanthin in quail, Measurement of carotenoids, retinoids, and tocopherols in human lenses. Send us an email with your question and we will get back to you within 48hrs. Use of vitamin supplements and cataract: the Blue Mountains Eye Study. Components of the AREDS2 formulation, donated by DSM Nutritional Products, include lutein/zeaxanthin supplied as water soluble triglyceride compounds and omega-3 LCPUFA formulation supplied in ethyl ester form as Ropufa 75 n-33 EE. Fruit, Herb, & Vegetable Infused Waters: Good Or Bad? For the same outcome, in subgroup analyses by quintiles of lutein/zeaxanthin intake, a comparison of lutein/zeaxanthin vs no lutein/zeaxanthin resulted in HRs of 0.64 (95% CI, 0.460.89; P = .008) and 1.26 (95% CI, 0.911.75; P = .17) for the lowest and highest quintiles of dietary lutein/zeaxanthin, respectively. A healthy, nutritious and varied diet, consisting of substantial amounts of fruit and vegetables, as well as nuts, seeds, fish and meat will, without a shadow of a doubt, help you to maintain not just healthy eyes, but general health as well. In the absence of any consensus about the importance of specific micronutrients, several controlled clinical trials have tested whether selected micronutrients with antioxidant characteristics or multivitamins affect cataract development.1117 Because of variable results, no clear treatment recommendation has resulted from the trials conducted to date.
