Inclusion criteria

* Patient has diagnosis of Diabetes Mellitus, Type I or II. * Patient has experienced the development of macular edema following cataract surgery in at least one eye. * Patient has had cataract surgery within 90 days prior to the screening visit.

Exclusion criteria

* Patient has other significant ocular disease in study eye, including glaucoma. * Patient has any active infection in the study eye. * Patient has uncontrolled systemic illness (i.e., uncontrolled blood pressure, uncontrolled diabetes mellitus). * Patient has experienced a significant increase in intraocular pressure following a prior treatment with topical or intravitreal steroidal medication. * Patient has received the OZURDEX® implant before in the study eye.

Participants by arm

ArmCount
DEX IMPLANT ARM
Subects in the DEX implant arm received a single intravitreal administration of 0.7 mg OZURDEX in the study eye at the Day 0 appointment. In order to minimize subject discomfort, adequate local anesthesia was administered to the study eye prior to DEX implant injection. Immediately following DEX implant injection, the investigator performed indirect ophthalmic exam to assess for complications. In order to minimize risk of infection, a topical broad-spectrum antibiotic was placed in the study eye immediately prior to and following the injection, and the subject were provided a sample of a broad-spectrum antibiotic to use 4 times daily for 3 days following injection. The subject remained in the clinic for 15-30 minutes or until IOP \<28 mmHg.
26
Topical Steroid/NSAID ARM
Subjects randomized to receive the steroid/NSAID eye drop combination therapy began treatment at Day 0. The first administration occurred in clinic. Subjects was instructed how to instill eye drops properly and to instill each drop in the study eye four times per day every day until month 1 visit. At each monthly visit, subjects in this arm were assessed for the need to continue steroid/NSAID therapy.
