The retina lines the inner surface of the eye, and is responsible for receiving visual images. The macula is the central part of the retina where the sharpest central vision is achievable. Macular edema refers to abnormal accumulation of fluid in the macula. As the macula swells, it produces blurry or distorted images. Because the macula is rich in photoreceptor cells responsible for color vision, perception of colors may also be impaired. These symptoms, however, may not be noticeable if only one eye is affected, because the good eye can often compensate for the diseased eye.
Macular edema occurs when damaged blood vessels of the retina leak blood or fluid into the macula. Any condition that affects blood vessels in the eye can cause macular edema. Common causes include:
– Diabetic retinopathy, a complication of diabetes;
– Age-related macular degeneration, in which abnormal blood vessels grow in the macula;
– Retinal vein occlusion, when drainage of blood is blocked, causing it to accumulate and leak;
– Inflammatory eye diseases, such as uveitis, where inflammation causes the macula to swell;
– and injuries to the eye
Macular edema may also occur as a complication of eye surgery, but in this case, it is usually mild and can be readily treated with anti-inflammatory eye drops.
Diagnosis can be made with a comprehensive dilated eye exam. Various imaging techniques can be performed to better visualize the retina.
The Amsler grid is a simple tool to check the acuity of central vision. Patients simply look at the grid, with one eye at a time. While a healthy eye sees all straight lines, an eye with macular edema will see wavy lines, missing part of the grid, or even dark spots. The larger the affected area, the more extensive the macular damage. The test is sensitive enough to detect even small changes in central vision.
Treatment of macular edema is directed at the underlying cause.
Medications known as “Anti-VEGF” are typically injected into the vitreous to stop the abnormal growth of blood vessels.
Several laser treatments are available to seal off leaky blood vessels or to shrink them.
Steroid medications in the form of eye drops, pills or injections, are used to treat inflammation.
Vitrectomy, a surgical procedure in which the vitreous is removed and replaced with a new fluid, can be performed if the condition is caused by the vitreous pulling on the retina.
