its development. But how can the bodys storage sites for iron be full without iron overflowing into other organs? 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. 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. In hhcs, components of ferritin accumulate in the eye lens and crystalize disrupting the light transmission which enables a person to see. People with hhcs typically have normal tibc and TS test results but elevated serum ferritin levels (. Iron accumulates in the body with age because we continue to absorb it from our diets, but we excrete very little, Dunaief said. This means that ferritin is constantly being made no matter whether iron levels are high or low. Iron may accumulate to even higher levels in diseased retinas because low oxygen levels (hypoxia) or inflammation can cause cells to retain iron. Right now, the only known treatment for hhcs is cataract surgery. An ophthalmologist confirms diagnosis of hhcs. 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. The answer is that a genetic mutation has turned off the bodys ability to make ferritin in response to changing iron levels. Attachment, posted on Mon, June 20, 2016 by Kayla Wiles. Age-related macular degeneration (AMD) is regarded as the leading cause of vision loss for people over the age. Hyperferritinemia means high ferritin in the blood). 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. 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. 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. Oftentimes the storage protein for iron, ferritin, can reach the eye instead of the mineral itself. Iron is a necessary mineral for many of the bodys functions, including vision.
