Everything You Need to Know about Sunglasses

Not everyone knows, but macular edema is the swelling or thickening of the macula of the eye, the part responsible for central and detailed vision.The macula is a very small area in the center of the retina.Edema arises when retinal blood vessels leak fluid because the macula does not function properly as it is damaged.

When edema appears in the macula, loss of vision may be mild or severe, however, in many cases, peripheral vision remains healthy.

Why does macular edema appear?

It is a complication of diabetic retinopathy. It is the most common form of vision loss among diabetics, especially if it is not treated in time. There are several causes of macular edema, and it is often associated with diabetes, which causes damaged blood vessels in the retina to lose fluid, including small amounts of blood. Here at BEST-MEDICAL-SCHOOLS you can get more different sunglasses  models and styles.

Occasionally, there may also be leaking fat deposits inside the retina, which causes the macula to become even more inflamed. Among the risk factors for macular edema are cataract surgery, which may increase the risk of developing macular edema due to irritation of the blood vessels.

Symptoms of macular edema

In addition to the aforementioned causes, there are other factors that may contribute to the onset of edema:

  • Age-related macular degeneration
  • Obstruction of small veins of the retina
  • Eye injuries
  • Side effects of certain medicines
  • Some tumors of the eye
  • Certain genetic disorders

Edema in the macula is relatively painless and may show few symptoms when it arises.However, when symptoms do occur, they are a sign that the blood vessels in the eyes may leak dangerously.

If you have symptoms of edema, consult an ophthalmologist immediately.When not treated properly, edema can cause vision loss and even lead to blindness.
