Study Summary

Laser photocoagulation and intravitreal anti-vascular growth factor injections are commonly used treatment options for individuals with diabetic macular edema. However, some patients continue to experience persistent diabetic macular edema and poor vision despite continued laser and/or anti-vegf therapy. Recent clinical trials suggest that due to inflammatory mediators dexamethasone intravitreal implant (0.7mg) may be a good alternative therapy for individuals unresponsive to laser photocoagulation or intravitreal anti-vascular growth factor injections. The purpose of this research study is to compare the effectiveness of using a dexamethasone steroid implant versus monthly intravitreal anti-VEGF injections for research participants with persistent diabetic macular edema (DME).

Primary Outcome

Mean change in central 1 mm sub-field thickness between baseline and 9 months as measured by Spectral Domain Optical Coherence Tomography (SDOCT).

Interventions

  • DRUG Dexamethasone intravitreal implant (0.7 mg)
  • DRUG Intravitreal anti-VEGF injection
