Macular edema
Macular Edema
Macular edema (pronounced: mack-yoo-lar eh-dee-muh) is a medical condition characterized by swelling or thickening of the macula, the part of the retina responsible for detailed, central vision.
Etymology
The term "macular edema" is derived from the Latin word "macula," meaning spot, and the Greek word "oídēma," meaning swelling.
Definition
Macular edema occurs when fluid and proteins collect on or under the macula of the eye causing it to thicken and swell (edema). This may distort a person's central vision, as the macula is near the center of the retina at the back of the eyeball.
Symptoms
Symptoms of macular edema can include blurred or wavy central vision, or colors appear washed out or changed. If you are experiencing any of these symptoms, it is important to see an ophthalmologist immediately.
Causes
Macular edema is often a complication of diabetic retinopathy, a condition that can occur in people with diabetes. Other conditions that can cause macular edema include retinal vein occlusion, age-related macular degeneration, and uveitis.
Treatment
Treatment for macular edema usually involves the use of corticosteroids or anti-VEGF drugs, which can be injected into the eye. In some cases, laser surgery may be required.
