2023年8月21日 · Macular edema happens when the macula swells. Read on to learn more about what symptoms of macular edema to watch out for, what the most common causes of macular edema are, and how...

2024年11月29日 · Macular edema is the buildup of fluid in the macula, an area at the back of the eye. This fluid causes the macula to swell and thicken, which distorts vision. Learn about the causes and symptoms of macular edema, how it’s diagnosed and treated, and what research is …

2024年9月23日 · Macular edema happens when fluid builds up in the macula, causing swelling. This can distort vision, making things look blurry and colors look washed out. Without treatment, macular edema can even lead to permanent vision loss. Macular edema is caused by pockets of fluid (usually leakage from damaged blood vessels) swelling up in the macula.

2024年10月26日 · Macular edema is swelling or fluid retention in a specialized part of the retina called the macula. The macula is located in the back of the eye and provides us with clear, central vision. It is the part of the retina we use when we "aim" our vision to look at a target. Fluid can build up in the macula from abnormal, leaking blood vessels.

2024年9月2日 · Macular edema is a condition where fluid accumulates in the macula, causing blurred or distorted vision. Causes of macular edema include diabetes, age-related macular degeneration, and retinal vein occlusion.

2024年7月5日 · Macular edema occurs when fluid or blood leaks into the retina. This builds up and causes swelling, resulting in changes in a person’s vision. The cells of the retina...

Macular edema is typically caused by increased leakage from damaged retinal blood vessels or growth of abnormal blood vessels in the deep retina. New vessels (neovascularization or NV) do not have normal “tight junctions” and almost always result in abnormal leakage of fluid (serum from the bloodstream) into the retina.

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).

2022年1月14日 · The primary underlying causes of macular edema are increased leakage from damaged retinal blood vessels, the growth of abnormal blood vessels in the deep retina, and the breakdown of the blood-retinal barrier. New blood vessels lacking normal tight junctions lead to abnormal serum leakage from the bloodstream into the retina.

2023年3月7日 · Macular edema is often caused by leakage of fluid from damaged or abnormal blood vessels in the retina. It can also be caused by leakage of fluid from the layer underneath the retina (the choroid), from the optic nerve (the connection from the eye to the brain), or the gelatinous contents of the eye (the vitreous humor).
