may accumulate to even higher levels in diseased retinas because low oxygen levels (hypoxia) or inflammation can cause cells to retain iron. 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. In hhcs, components of ferritin accumulate in the eye lens and crystalize disrupting the light transmission which enables a person to see.

Normally the RPE has ways to prevent iron from entering the retina when iron levels are high, but if iron export from cells is unregulated, iron may accumulate in the eye and degrade the macula.
