Right now, the only known treatment for hhcs is cataract surgery. 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. In hhcs, components of ferritin accumulate in the eye lens and crystalize disrupting the light transmission which enables a person to see. A liver biopsy will show that the patient does not have iron overload. The answer is that a genetic mutation has turned off the bodys ability to make ferritin in response to changing iron levels. 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. 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. Age-related macular degeneration (AMD) is regarded as the leading cause of vision loss for people over the age. This means that ferritin is constantly being made no matter whether iron levels are high or low. 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. Hyperferritinemia means high ferritin in the blood). 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 is a necessary mineral for many of the bodys functions, including vision. An ophthalmologist confirms diagnosis of hhcs.

|Cokin cokine schoten||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. Iron may accumulate to even higher levels in diseased retinas because low oxygen levels (hypoxia) or inflammation can cause cells to retain iron.
