Vision loss reversed with new stem cell therapy

A Phase 1 Clinical study of an experimental stem cell treatment for the web form of macular degeneration has resulted in two people having their vision loss reversed and their vision improving to being able to read with reading glasses. The study was published in Nature Biotechnology. Doctors used a surgical tool specifically designed for […]

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 […]

Broccoli design offers clue to improve retinal implants

Researchers at the University of Oregon are currently exploring the possibility that retinal implants with a fractal design might provide the first viable therapy in treating people who have lost vision due to retinal diseases. Implants that are currently being used have not demonstrated the kind of vision restoration that doctors and patients were looking […]

New Treatment for Damaged Eyes

Researchers at the University of Washington have discovered a way to activate retinal cells in mice to turn into new neurons. This discovery could potentially lead to new a new treatment for human eyes that have suffered from trauma or disease. A viral gene-swapping technique was used in the study. A version of a particular […]

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 […]
