Vegetables are good for maintaining eye health
Feb 14, 2012
A new study finds that high dietary intake of nutrients with antioxidant properties reduces the risk of early AMD in those at high genetic risk. Therefore, clinicians should provide dietary advice to young susceptible individuals to postpone or prevent the vision-disabling consequences of AMD. The etiology of AMD is complex with both genetic...

A logMAR visual acuity chart
Feb 11, 2012
Lutein-only and zeaxanthin-only supplementation for 12 months each increased macular pigment optical density (MPOD) and improved visual function in men with mild to moderate age-related macular degeneration (AMD). Macular pigment is composed principally of 2 isomeric carotenoids, lutein (L), zeaxanthin (Zx), and the L metabolite meso-Zx (...

N-acetyl-cysteine (NAC) inhibited the development of laser-induced choroidal neovascularization (CNV) in mice, according to a new study. Chemically, N-acetyl-cysteine (NAC) is similar to the amino acid cysteine. Amino acids are the building blocks of proteins. NAC is a potent antioxidant and has many uses in medicine. NAC acts as a cysteine...

Retinal pigment epithelium
Jul 25, 2010
Acetylcysteine (NAC) may help protect the retinal pigment epithelium (RPE) from the effects of chronic oxygen stress, according to a new study. NAC is a pharmaceutical drug and nutritional supplement used primarily as a mucolytic agent and in the management of acetaminophen overdose. It has also been shown to have antiviral effects in patients...

Fruits such as mangos are rich in lutein
Mar 20, 2009
A study on mice finds that lutein decreases retinal cell damage during inflammation. Lutein is a carotenoid that is concentrated in the retina. It is found in green leafy vegetables such as spinach and kale, and is also found in egg yolks. It is thought that lutein may help protect the retina from oxidative stress (antioxidant effect) and...

Senior women
Feb 25, 2009
A recent study finds that women taking folic acid and B vitamins supplements have a lower risk of developing age-related macular degeneration (AMD). Recent studies indicate a direct association between homocysteine concentration in the blood and the risk of AMD, suggesting that homocysteine may be a modifiable risk factor for AMD. Homocysteine...

Amsler grid distortion signals AMD
Feb 9, 2009
In most patients, AMD progresses relentlessly over decades, from asymptomatic precursor signs such as fine drusen and mild pigment dispersion to a more severe non-exudative AMD such as evidenced by geographic atrophy and, in some 20% of patients, to exudative AMD. Doctors who follow these patients today are forced to make many decisions that...

Erythropoietin protects cultured retinal pigment epithelial (RPE) cells from oxidative damage, making it potentially useful in the treatment and prevention of dry age-related macular degeneration (AMD), according to a recently published research report. Although the exact cause of dry AMD is not fully understood, it is believed that oxidative...

Sun
Oct 15, 2008
A new European population-based study finds that sunlight exposure increases the risk of wet AMD in those people with low serum antioxidant levels. It has been suggested that high-energy blue light from sunlight may be damaging to the retina. However, this is the first study to find an adverse association of blue light exposure with...
