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 different causes may be inter-related. Cystoid macular edema (CME) involves fluid accumulation in the outer plexiform
Edema person lie down in bed or sit with the feet propped up on cushions. Intermittent pneumatic compression can be used to pressurize tissue in a limb, forcing fluids – both blood and lymph – to flow out of the pressurized area. Treatment of persistent edemas, such as idiopathic bilateral lymphedema, may also use manual lymphatic drainage, a low-pressure massage technique designed to pump lymphatic fluid by a similar mechanism. Edema Edema, also spelled oedema or œdema, is an abnormal accumulation of fluid in the interstitium, located beneath the skin and in the cavities of the body, which can cause severe
