E-ETDRS = electronic Early Treatment Diabetic Retinopathy Study. SD-OCT = Spectral Domain optical coherence tomography. IOP = intraocular pressure. FA = Fluorescein angiogram. TAE=Treat and Extend. Bev=bevacizumab. Afl=aflibercept. Dex=Dexamethasone.

*

Includes both a dilated fundus examination and a slit-lamp examination.

Injection treatment between Months 1 and 5 is Bev or Afl, depending on initial randomization assignment. Good responders continue Bev or Afl on monthly or TAE schedule between Months 7 and 11 according to secondary randomization. Dex provided at Month 6 and PRN at Month 9, 10 or Month 11 in Poor or Marginal Responders initially randomized to Afl. Afl provided at Months 6, 7, 8 and TAE in Poor or Marginal Responders initially randomized to Bev.
