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. 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. Right now, the only known treatment for hhcs is cataract surgery. 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. This means that ferritin is constantly being made no matter whether iron levels are high or low. But how can the bodys storage sites for iron be full without iron overflowing into other organs?
