PREVENTING AMD WITH OMEGA-3 AND FISH. A total of 38,022 women, who were not diagnosed with AMD and had an average age of 55, completed food-frequency questionnaires. A 10-year follow-up revealed 235 cases of AMD. Women with the highest intake of EPA and DHA omega-3s had a 38% lower risk of AMD than those with the lowest intake. In addition, women who consumed one or more servings of fish per week had lower risk of AMD compared to those who consumed less than one serving per month.

VEGETARIANISM AND CATARACT RISK. Previous studies of diet and cataract risk have focused on specific nutrients or healthy eating indexes but not on identifiable dietary groups such as vegetarians. This study investigated the association between diet and cataract risk in 27,670 self-reported, non-diabetic participants aged 40 and above in Britain who have a wide range of diets, including a high proportion of vegetarians. It was concluded that vegetarians were at lower risk of cataract than meat eaters.

ORDER OF IOP MEASUREMENTS. A total of 105 healthy volunteers at Washington University were randomized into two groups: one had three sets of two intraocular pressure (IOP) measurements per eye, starting with the right eye, and the other group started with the left eye. After two weeks, the measurement order was reversed. IOP measured in the first eye, whether right or left, was higher than IOP measured in the next eye; this maybe partially due to ocular squeezing. It was concluded that multiple IOP measurements at multiple visits are necessary to accurately diagnose and treat patients.

WEARING SWIMMING GOGGLES LIMITS CL BACTERIA. Some of the 23 subjects wearing silicone hydrogel or hydrogel contact lenses were given goggles to wear while swimming for 30 minutes in two sessions in a salt water pool in Sydney, Australia. At the end of each session, lenses were collected for microbial analysis. Consistently, fewer bacterial colonies were found on the goggled contact lens, suggesting goggles offer some protection against bacteria in contact lenses while swimming.

ANTIOXIDANTS IN GOJI BERRY BENEFIT VISION. This double-masked, randomized, placebo-controlled trial evaluated effects of daily supplementation with a milk-based formulation of goji berry (Lacto-Wolfberry) in healthy elderly subjects aged 65 to 70. Subjects received 13.7 grams a day of Lacto-Wolfberry or placebo for 90 days. Overall, supplementation with goji berry increased plasma zeaxanthin and antioxidant levels as well as protected from hypopigmentation and soft drusen accumulation in the macula.
