A cataract is a dense, cloudy area that forms in the lens of the eye. A cataract begins when proteins in the eye form clumps that prevent the lens from sending clear images to the retina. The retina works by converting the light that comes through the lens into signals. It sends the signals to the optic nerve, which carries them to the brain. It develops slowly and eventually interferes with your vision. Cataracts are common in older people. There are different types of cataracts.

Red blood cells are produced in the bone marrow and have a life span of about days. The bone marrow is always making new red blood cells to replace old ones. Millions of new red blood cells enter the blood stream each day in a healthy person. You need certain nutrients in your diet to make and maintain red blood cells. Each red blood cell contains a protein called haemoglobin. This protein gives red blood cells their colour.

Megaloblastic anemias result most often from deficiencies of vitamin B12 and folate. Ineffective hematopoiesis affects all cell lines but particularly red blood cells. Diagnosis is usually based on a complete blood count and peripheral smear, which usually shows a macrocytic anemia with anisocytosis and poikilocytosis, large oval red blood cells macro-ovalocytes , Howell-Jolly bodies residual fragments of the nucleus , hypersegmented neutrophils, and reticulocytopenia. Treatment is directed at the underlying disorder. See also Overview of Decreased Erythropoiesis. Megaloblasts are large nucleated red blood cell RBC precursors with noncondensed chromatin due to impaired DNA synthesis. Macrocytic RBCs occur in a variety of clinical circumstances, many unrelated to megaloblastic maturation.

The association of dysphagia, superficial glossitis and anemia has been noted sufficiently frequently during the past few years to have become regarded as a clinical entity, and has often been referred to as the "Plummer-Vinson syndrome.
