Megaloblastic Anemia (MGA), also known as Pernicious Anemia, is a rare blood disorder characterized by the presence of large, structurally and visually abnormal, immature red blood cells (megaloblasts). Decreased numbers and immaturity of white blood cells (leukocytes) and blood platelets (thrombocytes) may also occur.
6. Reflective Tissue: Deer have a layer of tissue in their eyes that reflect light back towards the photo-receptors. This tissue layer is called tapetum lucidum and helps deer see better during low light conditions (e.g, dusk and dawn) and makes their eyes appear to glow when reflecting light (e.g., headlights).Many other animals have this tissue layer as well.his tissue layer is called tapetum lucidum and helps deer see better during low light conditions (e.g, dusk and dawn) and makes their eyes appear to glow when reflecting light (e.g., headlights).

Itâs the tapetums cause the eerie glow that we see in a housecatâs eyes caught in a light or when our car headlights surprise a deer, or badger. The color of eyeshine varies from species to species.
