* BCVA ETDRS letter score ≥ 34 in the fellow eye
Exclusion Criteria:
* Macular edema due to causes other than DME in the study eye
* Concurrent disease in the study eye, other than DME, that could require medical or surgical intervention during the study period or could confound interpretation of the results
