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. 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.

Transferrin-iron saturation percentage (TS) : a measure of iron carried by the protein transferrin in the serum; represented by fasting serum iron divided by total iron binding capacity (tibc multiplied by 100. Oftentimes the storage protein for iron, ferritin, can reach the eye instead of the mineral itself. In hhcs, components of ferritin accumulate in the eye lens and crystalize disrupting the light transmission which enables a person to see. Iron is a necessary mineral for many of the bodys functions, including vision. People with hhcs typically have normal tibc and TS test results but elevated serum ferritin levels (.

An ophthalmologist confirms diagnosis of hhcs. Age-related macular degeneration (AMD) is regarded as the leading cause of vision loss for people over the age. Joshua Dunaief, professor of ophthalmology at the University of Pennsylvania School of Medicine. Iron contributes to the leading causes of vision loss. Iron chelation therapy is the removal of excess iron from the body with special drugs. If an hhcs patient is falsely diagnosed with hemochromatosis, phlebotomies used to remove excess iron from the body could make the person become iron deficient. Iron may accumulate to even higher levels in diseased retinas because low oxygen levels (hypoxia) or inflammation can cause cells to retain iron. Iron accumulates in the body with age because we continue to absorb it from our diets, but we excrete very little, Dunaief said. 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.

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. The answer is that a genetic mutation has turned off the bodys ability to make ferritin in response to changing iron levels. While smoking, poor diet, and lack of exercise typically contribute to oxidation of the retina, research has found that iron may also increase a persons risk of AMD, according. Home / Iron Blog, iron contributes to the leading causes of vision loss. This means that ferritin is constantly being made no matter whether iron levels are high or low. Hyperferritinemia means high ferritin in the blood). But how can the bodys storage sites for iron be full without iron overflowing 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.
