Possible causes

  • Macular edema

    Macular edema is the buildup of fluid in the macula, the area in your retina responsible for central vision. Macular edema occurs when there is fluid leading to swelling in the macula. This buildup of fluid will lead to blurring of vision and vision loss in severe cases. Macular edema can be commonly caused by a blockage in your retinal arteries or veins as well as diabetes.

  • Cataracts

    Degeneration of the lens inside the eye, causing it to become opaque. As a result, lights appear glaring and vision becomes blurred. In the elderly, cataracts are usually caused by aging, In children however, it may be due to genetic conditions, drugs, or viral infections while in the womb.

  • Diabetic macular edema (DME)

    Diabetic macular edema is caused by the condition when tiny bulges (microaneurysms) protrude from the vessel walls, leaking or oozing fluid and blood into the retina. This fluid can cause swelling (edema) in the central part of the retina (macula) and it may cause vision problems or blindness.

  • Pathologic myopia

  • Branch retinal vein occlusion
  • Candidiasis (oral, hands and feet)
  • Acromegaly
