A recent study published in the journal “Archives of Ophthalmology” showed an inverse link between vitamin C and cataracts. This Indian study was a population-based cross-sectional analytic study measuring the plasma vitamin C levels in 5638 people 60 years of age or older. These people were checked for cataracts and type of cataracts.

Low levels of lutein, zeaxanthin, retinol and vitamin C all showed to be correlated to cataracts. However, low vitamin C levels had by far the strongest association and were also consistent by type of cataract.

The U.S. Food and Drug Administration recently announced that it has approved new technology that could help improve vision to people age 75 or older with end-stage, age-related macular degeneration.

The Implantable Miniature Telescope (IMT) just approved by the FDA is a first-of-its kind device, according to the manufacturer, VisionCare Ophthalmic Technologies.

New study found that medications that increase sensitivity to the sun,  including antidepressants, diuretics, antibiotics and the pain reliever naproxen sodium (commonly sold over-the-counter as Aleve) increase the risk of age-related cataract.

The results of this study will be in the publication in the August print issue of the Archives of Ophthalmology.

Editor’s Notes: The lens cells are similar to skin cells which may be why additional light sensitivity can contribute to or cause cataracts.

New research announced at Diabetes UK’s Annual Professional Conference links Diabetic retinopathy with poorer memory and diminished brain power in people with Type 2 diabetes. It has yet to be determined whether the advance of cerebral microvascular disease, as indexed by retinopathy, leads to cognitive decline or whether poorer mental acuity makes it more difficult to manage diabetes symptoms and leads to a worsening of the disease. According to Jie Ding from the University of Edinburgh, “It is also possible that a third unidentified factor is causing both diabetic retinopathy and the cognitive changes.” Source: http://www.medicalnewstoday.com/articles/181324.php

Researchers at Tennessee’s Oak Ridge National Laboratory have announced that they have developed a machine that allows early diagnosis and treatment of diabetic retinopathy.  The Telemedical Retinal Image Analysis and Diagnosis technology, known as TRIAD is meant to make it possible to screen for the disease at doctor’s offices.

Diabetes related blindness is largely preventable if patient and the medical team work together diligently. With timely treatment, 90 percent of those with advanced diabetic retinopathy can be saved from going blind.  Learn more at:http://www.naturaleyecare.com/diseases.asp?d_num=4

About 33 million Americans in all age groups experience varying degrees of dry eye symptoms. The symptoms may include dryness, grittiness, irritation, burning and even the seeming contradiction of excessive watering or tearing.

Dry eyes are a condition of the entire body, not just the eyes, and should be addressed as such, meaning that those who suffer from this condition should consider making changes to their diet and introducing nutritional supplements.  One of the most important aspects for people who suffer from dry eyes is the prohibition against sugar and/or artificial sweeteners. Sugar increases the risk for dry eyes.

In an analysis of the genes of more than 1,000 patients with age-related macular degeneration (AMD), an international team of scientists discovered a strong association between the vision problem and the presence of a new gene.

The new gene connection is with hepatic lipase gene LIPC, a critical enzyme in the metabolism of high-density lipoprotein (HDL). The study also noted strong associations between advanced AMD and other single nucleotide polymorphisms in the same lipid pathway, but the other finding showed a much stronger, genome-wide significance.

Study shows supplementing with zeaxanthin (a carotenoid in the lutein family) can raises macula pigment optical density (MP) and has unique visual benefits for patients with atrophic early AMD having visual symptoms.

Zeaxanthin can be found in dark, leafy greens (like turnip greens, collard greens, kale, spinach and romaine lettuce). Orange peppers are the highest source of zeaxanthin.

Many research studies show the value of supplementing with lutein and zeaxanthin in helping to preserve vision for those with macular degeneration. Additional studies show mesozeaxanthin (a member of the lutein family), as an essential nutrient for helping preserve vision for those with macular degeneration, used in the eyes as an antioxidant in the center of the macular where our detailed vision comes from.

The referenced study is one of 3 completed to date demonstrating the value of supplementing with this mesozeaxanthin.

A new study, known as Meso-zeaxanthin ocular supplementation trial (MOST), begins in late March 2010 and the clinical research team are currently recruiting suitable candidates. The specialists involved in the trial are research experts in this area of eye disease. The trial requires 60 patients who have been diagnosed with early AMD. After a complimentary eye screening by an IVR Ophthalmologist, suitable candidates will be enrolled into the trial and provided with a 12-month course of dietary supplements containing the macular pigments.

For further information on AMD or on the MOST trial being conducted at the Institute of Vision Research, please contact: Eithne Connolly, Clinical Research Technician, on 051 302153 or at eithneativr.ie

Editor’s Note: Recent studies have shown that mesozeaxanthin is another carotenoid in the family of lutein and zeaxanthin essential for macular degeneration, and is used as an antioxidant directly in the center of the retina. Hopefully this study will further confirm that this nutrient along with a family of other essential nutrients helps preserve vision for those with macular degeneration.
