The answer is that a genetic mutation has turned off the bodys ability to make ferritin in response to changing iron levels. A liver biopsy will show that the patient does not have iron overload. 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. Iron contributes to the leading causes of vision loss. Oftentimes the storage protein for iron, ferritin, can reach the eye instead of the mineral itself. But how can the bodys storage sites for iron be full without iron overflowing into other organs?
Age-related macular degeneration (AMD) is regarded as the leading cause of vision loss for people over the age. Iron may accumulate to even higher levels in diseased retinas because low oxygen levels (hypoxia) or inflammation can cause cells to retain iron. 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. 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. 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. Home / Iron Blog, iron contributes to the leading causes of vision loss. People with hhcs typically have normal tibc and TS test results but elevated serum ferritin levels (. 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 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. 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. Joshua Dunaief, professor of ophthalmology at the University of Pennsylvania School of Medicine. 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 is a necessary mineral for many of the bodys functions, including vision. 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.
