High levels of amino acid may be linked to increased AMD risk
People who have elevated homocysteine in their blood, an amino acid that is a known biomarker for cardiovascular disease, may also be at an increased risk of developing age-related macular degeneration (AMD), according to a study in the January issue of the American Journal of Ophthalmology. This research was conducted at the Massachusetts Eye and Ear Infirmary and Devers Eye Institute in Portland, Ore.
In this largest study of the relationship of this amino acid and AMD, researchers measured the fasting plasma homocystein levels of 934 individuals who were participating in an ancillary study of the Age-Related Eye Disease Study. Five hundred and forty seven people with AMD and 387 control subjects were tested.
