Researchers testing eye implant for macular degeneration

Researchers are testing a new therapy for treating macular degeneration that utilizes implanting a thin sheet of human embryonic stem cells into the eye. This eye implant would be used to treat patients suffering from the dry form of macular degeneration. University of Southern California researchers grew human embryonic stem cells in a sterile lab […]

Sex hormones affect eyes

A study published online in the Journal of Cellular Physiology suggests that fluctuations in sex steroid homeostatis may have a direct impact on eye physiology and on eye diseases such as age-related macular degeneration. Researchers from Temple University’s Sbarro Institute were looking to determine whether male gender can be considered a risk factor in developing age-related […]

Study compares Lucentis regimens for wet AMD

The treat-and-extend (TE) protocol of Lucentis (ranibizumab) is just as effective as a monthly regimen of ranibizumab when looking at increasing visual acuity in patients with neovascular age-related macular degeneration (AMD). The 12-month study was conducted in Portugal and led by Rufino Silvia, MD, PhD and involved 650 wet AMD patients aged 50 and older. […]

Fruit fly eyes helpful in understanding human blindness

Scientists have long understood that blue light will make fruit flies go blind but had been unable to determine why. A recent Purdue University study revealed how blue light kills cells in the eyes of the fruit fly and opens up the possibility of further understanding human eye diseases such as macular degeneration. Researchers compared […]

Women are #1 in Vision Problems

When it comes to problems with eyes and vision, more women than men are affected and the reason for this disparity is unknown. Worldwide statistics indicate that women account for two-thirds of the visually impaired or blind. In the United States, almost 2.7 million women over the age of 40 have low vision or are […]

BREAKTHROUGH – Blood test for Macular Degeneration?

Researchers at Massachusetts Eye and Ear have found that a particular set of metabolites in the blood are good markers for diagnosing AMD as well as indicating the severity of Macular Degeneration Metabolites, or breakdown products, are a result of both genes and environment. The “metabolome” — the set of metabolites present in an individual — […]

Effects of blue light exposure reduced with lutein and zeaxanthin

Benefits of lutein and zeaxanthin supplementation on blue-absorbing macular pigment, sleep quality and visual performance The results of the study were published in Foods. The macular carotenoids, lutein and zeaxanthin isomers, are known as high-energy blue light filters. Blue light penetrates deep into the eye and can cause the formation of free radicals. In the […]

New drug for Macular Degeneration

Genetech is currently studying a new drug, lampalizumab, to treat age-related macular degeneration. The drug is designed to slow the destruction of light-sensing cells in the retina. When those cells die, they are unable to regenerate, which causes permanent vision loss. 129 patients participated in the 18-month study and received monthly eye injections. The patients […]

Lutein levels in the eye linked to higher achievement in children

Two recent studies demonstrated that children who do better in school have higher lutein levels in the eye. Even after taking in consideration other factors including IQ, gender, body composition and physical fitness, children that had higher lutein levels did better on cognition tests and performed better academically. In the first study, researchers measured lutein […]

Optometrists more likely than ophthalmologists to recommend eye supplements

A recent study was conducted among Swedish optometrists and ophthalmologists that examined use of nutritional supplements, dietary advice, smoking and eye diseases and strength of evidence and the sources of information used for supplement recommendations. Optometrists responded at a much higher rate to the questionnaire used in the study at a rate of 40.3% compared […]
