into other organs? Dunaiefs research has shown that the oral iron chelator deferiprone may be a possible treatment for AMD if iron accumulation was one of the causes for its development. People with hhcs typically have normal tibc and TS test results but elevated serum ferritin levels (. Iron contributes to the leading causes of vision loss. Iron may accumulate to even higher levels in diseased retinas because low oxygen levels (hypoxia) or inflammation can cause cells to retain iron. Iron chelation therapy is the removal of excess iron from the body with special drugs.

This means that ferritin is constantly being made no matter whether iron levels are high or low. 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. Joshua Dunaief, professor of ophthalmology at the University of Pennsylvania School of Medicine.

The macula, a small portion of the retina which is responsible for sharp and detailed vision, deteriorates over time when the retinal pigment epithelium (RPE) surrounding the macula oxidizes triggering an inflammatory response. Normally the RPE has ways to prevent iron from xoxx video com blå film en video
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. The answer is that a genetic mutation has turned off the bodys ability to make ferritin in response to changing iron levels. The result is hereditary hyperferritinemia cataract syndrome (hhcs an inherited condition of early-onset cataracts which could be dangerously confused with hemochromatosis (iron overload) unless a person is diagnosed using the full iron panel : Hemoglobin : the iron-containing protein in the blood that carries iron. Hyperferritinemia means high ferritin in the blood).
