Lutein plus vitamin A may slow vision loss

Lutein plus vitamin A may slow vision loss: Study: "A daily supplement of lutein in combination with vitamin A may slow vision loss associated with retinitis pigmentosa, according to the results of a randomized, controlled, double-blind trial.
Writing in the Archives of Ophthalmology, American scientists report that a daily supplement containing 12 milligrams of lutein in combination with 15,000 International Units of vitamin A (retinyl palmitate) was associated with a preservation of mid-peripheral vision.

Rentinitis pigmentosa is a group of inherited eye diseases that affect the retina. It causes the degeneration of photoreceptor cells in the retina, bringing progressive vision loss to about one in 4,000 people worldwide. Previous studies had found that taking vitamin A slows the decline in retinal function and vision loss."
