Totally free dating sites xxx dateThe 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. 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. Hyperferritinemia means high ferritin in the blood). The answer is that a genetic mutation has turned off the bodys ability to make ferritin in response to changing iron levels. 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.

But how can the bodys storage sites for iron be full without iron overflowing into other organs? 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. People with hhcs typically have normal tibc and TS test results but elevated serum ferritin levels (. A liver biopsy will show that the patient does not have iron overload. Iron is a necessary mineral for many of the bodys functions, including vision.
