But too much iron or problems with utilizing, storing, or transporting iron properly can lead to vision loss in the form of conditions such as age-related macular degeneration and hyperferritinemia syndrome, according to recent research findings. Iron contributes to the leading causes of vision loss. Deferiprone can protect the retinas of mice by entering the retina and removing iron from it, said Dunaief, whose lab is currently testing additional drugs to prevent iron accumulation in the eye. Iron accumulates in the body with age because we continue to absorb it from our diets, but we excrete very little, Dunaief said. In hhcs, components of ferritin accumulate in the eye lens and crystalize disrupting the light transmission which enables a person to see.
