Diabetic Macular Edema; Definition, Causes, Symptoms, And treatment - Healthintimation

What is Diabetic Macular Edema?

Diabetic Macular edema: Inflammation of the retina in diabetes mellitus due to fluid leakage from the blood vessels within the macula. The macula is the central part of the retina, a small area rich in a cone, the special nerve ending detects the color and which depends on the day's vision.
Macular edema occurs when the fluid and the protopollocyte gather on or below the macula of the eye and it gets thick and swollen (Edima).

Diabetic Macular Edema is classified as Focal and Diffuse type. This is an important difference because there are two types of treatment different. Focal macular edema vascular abnormalities, mainly due to the foci of microaneurism, which leak fluid, while the diffuse macular edema is due to thin retinal capillaries in the retina.
Diabetic macular edema affects 30% of people who have diabetes for 20 years or more, and if untreated, then 20 to 30% of people who have experienced moderate visual impairment.

What're the causes of Diabetic Macular Edema?

DME is an eye condition in people with diabetes - both types 1 and types 2
When the fluid stays in your retina, it can cause diabetes mellitus edema. Leaking causes your retina to swell, which inhibits the function of your macula, a special, sensitive part that gives you sharp vision.
Due to the poor glucose control over time, high blood sugar can cause harm to the small blood vessels of the body, including the eye. Diabetic Retinopathy is a disease that damages blood vessels in the retina, which results in loss of vision. Left untreated, fluid can leak into the center of the macula, which is called fovea, where the eye part is fast, straight-forward vision. The fluid macula flows, the blur appears. This situation is called DME. It can occur at any stage of diabetic retinopathy, although this disease is more likely to increase.
High blood sugar weakens blood vessels in your eyes. It can be leakage or beyond the control of your eye, in the light-sensitive area in your retina. This is called diabetic retinopathy.

What are the symptoms of speckled edema of diabetes?

It is possible to have long-term diabetic retinopathy without having to note the symptoms until the damage is not done. Some patients may have a partial or total loss of vision. Some other symptoms include:/ Blurring or dual vision, difficulty reading, flats, pain in the region of vision, pain in the eye or pressure, and difficulty with color perception.

Those who have diabetes, are at risk of developing DME over time. The person with diabetes should check their vision yearly, or be directed by their eye doctor. Vision changes due to DME are:

  • Blurred vision
  • double vision
  • The Sudden increase in eyes floaters

How is Diabetic Macular Edema treated?

To treat diabetic macular edema, doctors can use medicines that are injected into your eyes to help prevent leakage,/ and slow down the development of new blood vessels. These drugs include: Aya, Illuvien, Lucentis (Renjumab), McGugen (Pegaptanib)

A doctor can leak blood vessels on your eye using a small laser. It is not usually painful, but when the laser touches you, you may feel a lightweight prick.
Sometimes steroid injections can help.
Another treatment is a surgery called Vitrectomy. This is usually caused by bleeding (not macular edema), and doctors take out the fluid that destroys your vision and changes it with a clear solution.
