eye and degrade the macula. A liver biopsy will show that the patient does not have iron overload. 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. Oftentimes the storage protein for iron, ferritin, can reach the eye instead of the mineral itself. Attachment, posted on Mon, June 20, 2016 by Kayla Wiles.
