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. Age-related macular degeneration (AMD) is regarded as the leading cause of vision loss for people over the age. Oftentimes the storage protein for iron, ferritin, can reach the eye instead of the mineral itself. In hhcs, components of ferritin accumulate in the eye lens and crystalize disrupting the light transmission which enables a person to see. 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.
