Omega-3s improve vision in AMD
by Newsletter Editor
Age-related macular degeneration (AMD), which gradually reduces eyesight in the center of the field of vision, is the most common form of age-related blindness. Dry AMD, affecting 90 percent of those with AMD, is the most common type. In dry AMD, the layer of pigment cells that helps protect light-sensitive cells in the eye wears thin and breaks down.
A small pilot study of those with dry AMD who took omega-3s was recently conducted. Participants took 3,400 mg of EPA per day or 1,600 mg of DHA per day, with no placebo group. This was a six-month trial, but by the middle of the fourth month, all participants in both omega-3 groups had significant improvements in visual acuity, seeing clearly at least one additional line in standard vision tests.
Doctors said these results are striking because there is no existing treatment for dry AMD and believe that the positive findings may be partly due to the higher dosage of omega-3s compared to prior AMD studies.
