What is Diabetic Retinopathy?
Diabetic Retinopathy is the leading cause of visual impairment among people of working age and has social consequences beyond sight loss. It has been also noted as the most frequent cause of blindness among adults aged 20 to 74 years old. Molecular and physiologic abnormalities found to develop in the retina for individuals with diabetes are consistent with inflammation.
Why is Diabetes linked to Retinopathy?
As of the worldwide statistics, diabetes mellitus affects 200 million people worldwide. As lifelong progressive disease and as result of the body's inability to produce insulin or use insulin through its full potential-characterized by high circulation glucose, diabetic retinopathy remained to be difficult to prevent and treat. As retinopathy involves all the major cell types of the retina and the same systemic cardiovascular risk factors which increases the risk of stroke, myocardial infarction, and renal failure.
What are the symptoms of Diabetic Retinopathy?
- Black spots or floaters in the field of vision.
- Cataract which is more common for diabetic patients.
- Reduced night vision.
- Patches or streaks due.
- Sudden vision loss due to large bleeds or hemorrhage.
- Retinal detachment/ Diabetic macular edema
What are the management options for Diabetic Retinopathy?
- LASER to seal leaking vessels, to decrease or prevent swelling and to improve blood circulation of the healthy retina.
- intraocular injection to help sealing leaking vessels to improve and preserve the retina.
- Surgery or Vitrectomy to restore the retina's condition.
- Cataract surgery for removal of cataract and intraocular lens.

Did You Know?
Most important factor in medical management of diabetic retinopathy is good glycemic control, which is associated with reduced risk of newly diagnosed retinopathy and of progression of existing retinopathy.
