Diabetic Retinopathy Causes Early Symptoms and Risk Factors

Diabetic retinopathy is an eye disease linked to diabetes.
It affects the retina which is the light sensitive part at the back of the eye.
High blood sugar can damage small blood vessels in the retina.
If not treated early it can lead to vision loss.
Early detection helps protect eyesight.
What Is Diabetic Retinopathy
Diabetic retinopathy happens when diabetes damages the blood vessels in the retina.
These blood vessels may:

• Leak fluid
  
• Swelling may occur
  
• Bleeding can happen
  
• New weak vessels may grow
  

Damage to the retina affects clear vision.
Causes of Diabetic Retinopathy
The main cause is uncontrolled blood sugar.

• High blood sugar over time damages blood vessels.
  
• Long term diabetes increases risk.
  
• High blood pressure can worsen damage.
  
• High cholesterol can also affect blood vessels.

Proper diabetes control reduces risk.
Early Symptoms of Diabetic Retinopathy
Early stages may not show strong symptoms.

• Mild blurred vision

Many people do not notice symptoms early.
Regular eye exams are very important.
