Diabetic Retinopathy

People who have diabetes can have an eye disease called diabetic retinopathy. This is when high blood sugar levels cause damage to blood vessels in the retina.

Diabetic Retinopathy is classified into 2 types:

1. NPDR (Nonproliferative diabetic retinopathy):

It is an early stage of Diabetic Eye Diseases In which, the blood vessels can swell and leak. Many people having diabetes face this type of Diabetic Retinopathy.
Non-Proliferative Diabetic Retinopathy is a condition in which tiny blood vessels leak leading to the swelling in the macula of the retina which is called as Macular Edema. This is one of the most common reasons why people with diabetes lose their vision.

NPDR can also lead to a condition named as muscular ischemia which closes of the blood vessels in the retina i.e a condition in which the blood vessels cannot reach macula. This can be caused due to a collection of some tiny particles called exudates in the retina which affects the eye sight.

Nonproliferative Diabetic Retinopathy leads to blurry vision.

2. PDR(Proliferative Diabetic Retinopathy):

Proliferative Diabetic Retinopathy Is the most advance type of Diabetic Eye Disease and is a condition which retina starts growing new blood vessels also called as neovascularization. These new vessels are very fragile and thus very often bleed into the vitreous. A dark floater appears in this condition. If they only bleed a little, you might see a few dark floaters. If they bleed a lot, it might block all vision.

The new blood vessels can form scar tissue which can cause retina detachment or lead to problems in the macula.

As mentioned above Proliferative Diabetic Retinopathy is a very serious issue and can steal both your peripheral(Side) and central vision


The connection between Diabetes mellitus and Diabetic Retinopathy:

1. The severity of Diabetic Retinopathy and the duration of Diabetes Mellitus walk hand in hand.
2. A regular checkup must be taken up every 6 to 12 months can help detect early changes and prevent blindness

Symptoms of Diabetic Retinopathy:

There are no symptoms in the early stage of Diabetic Retinopathy, however as the condition progresses you may face the following signs and symptoms:

  • a) Dark Spots or Strings floating in your vision also known as floaters
  • b) Blurry Vision
  • c) Fluctuation in the Vision
  • d) Impaired Color Vision
  • e) Dark or Empty Areas in your Vision
  • d) Vision Loss

In most of the cases, diabetic retinopathy affects both the eyes.

2. Medication :

There is a medicine called Anti- VEGF which helps to reduce the swelling in the macula by slowing down the vision and gradually improving it.

3. Laser Treatment :

Lasers are used to seal the leaking blood vessels, which helps in reducing the swelling of the retina. It is also used to shrink the blood vessels and stop them from growing again.

4. Vitrectomy :

This Surgery is suggested by an ophthalmologist only when one faces Advance Proliferative Diabetic Retinopathy. During the surgery, Ophthalmologist vitreous gel and blood from leaking vessels in the back of your eye which allows light rays to focus properly on the retina again. Scar tissues might also be removed from the retina during this surgery for better vision.

5. anti-VEGF injections :

One type of medication is called “anti-VEGF” medication. This helps to reduce swelling of the macula, slowing vision loss and perhaps improving vision. This drug is given by injections (shots) in the eye. Steroid medicine is another option to reduce macular swelling. This is also given as injections in the eye. Your doctor will recommend how many medication injections you will need over time.
