Causes of Diabetic Retinopathy
The elevated blood glucose levels (hyperglycemia) in a patient with diabetes results in:
- Retinal blood capillary leakage & occlusion
- Retinal & macular edema
- Formation of new blood vessels & fibrous tissue – in proliferative diabetic retinopathy
Signs and symptoms
Early diabetic retinopathy is usually asymptomatic. As disease progresses, you may notice:
- Having a dark or empty spot in the center of your vision
- Distortion of shapes
- Reduced central vision
- Severe loss of vision
Diabetic Retinopathy Treatment
- Laser treatment to seal leaking blood vessels or to halt new blood vessels from forming
- Vitrectomy (surgical procedure) to remove and replace the gel-like fluid in the back of the eye, called the vitreous. This may be needed in patients with proliferative diabetic retinopathy.
