Macular edema is the accumulation of fluid in the macula, the part of your retina responsible for central vision. It occurs when fluid leads to swelling in the macula, causing blurred vision and vision loss in severe cases. Common causes of macular edema include blockages in retinal arteries or veins and diabetes.
Degeneration of the lens inside the eye causes it to become opaque. As a result, lights appear glaring and vision becomes blurred. In older adults, cataracts are usually caused by aging. In children, however, they may be due to genetic conditions, drugs, or viral infections while in the womb.
Diabetic macular edema (DME)
Diabetic macular edema occurs when tiny bulges (microaneurysms) protrude from the vessel walls, leaking fluid and blood into the retina. This fluid can cause swelling (edema) in the central part of the retina (macula) and may lead to vision problems or blindness.
Pathologic myopia
Low blood sugar levels. This can be fatal as the brain depends on sugar for energy. It is usually caused by diabetes medications, but can also be caused by hormone disorders and insulin overproduction.
