Diabetic retinopathy
According to research done by the National Eye Institute, prompt treatment of diabetic macular edema with the drug Lucentis, with or without laser treatment, resulted in better vision than laser treatment alone, or steroid injections. When injected into the eye, Lucentis, and two other similar drugs, Avastin or Aylea, reduce fluid leakage and interfere with the growth of new blood vessels in the retina.
