Macular edema eye can result in improved visual outcomes for patients with chronic or refractory diabetic macular edema. Macular edema Macular edema occurs when fluid and protein deposits collect on or under the macula of the eye (a yellow central area of the retina) and causes it to thicken and swell (edema). The swelling may distort a person's central vision, because the macula holds tightly packed cones that provide sharp, clear, central vision to enable a person to see detail, form, and color that is directly in the centre of the field of view. The causes of macular edema are numerous and
Tissue culture growth of cells from a tissue from a multicellular organism "in vitro". These cells may be cells isolated from a donor organism, "primary cells", or an immortalised cell line. The cells are bathed in a culture medium, which contains essential nutrients and energy sources necessary for the cells' survival. The term tissue culture is often used interchangeably with cell culture The literal meaning of tissue culture refers to the culturing of tissue pieces, i.e. explant culture. Tissue culture is an important tool for the study of the biology of cells from multicellular organisms. It provides an "in vitro" model of
