5 Key Takeaways

1

The DRCR Retina Network was established in 2002 to conduct large clinical trials on diabetic retinopathy and diabetic macular edema.
2

Intravitreal anti-VEGF injections were shown to be more effective than laser treatment for diabetic macular edema in early DRCR studies.
3

The network has expanded its focus to include all retinal diseases, applying successful collaborative research strategies.
4

Recent studies indicate that anti-VEGF treatments can improve diabetic retinopathy severity and visual outcomes.
5

The ongoing Protocol AF aims to evaluate the effects of fenofibrate on preventing worsening of diabetic retinopathy.
