What Is Macular Edema? Macular edema is swelling or thickening of the eye's macula, the part of your eye responsible for detailed, central vision. The macula is a very small area at the center of the retinaâa thin layer of light-sensitive tissue that lines the back of the eye.
What is perception? The process by which individuals select, organize, and interpret the input from their senses (vision, hearing, touch, smell, and taste) to give meaning and order to their environment. Through perception, people try to make sense of their environment and the objects.
There are two types of perception; the way you see yourself and your world and the way others see you and their world. The only perception you have control over is your own. It is just not possible to control the perception of others. For example, consider the temperature of a room. You perceive a room as being comfortable while someone else thinks itâs too cold.
