Primary Outcome Measures:
  • The change in visual acuity (number of ETDRS letters). [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    The measure the change in ETDRS letters for each treatment group from baseline to 6 months.

  • The change in central foveal thickness (microns on high resolution OCT). [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    The measure the change in central foveal thickness for each treatment group from baseline to 6 months.


Secondary Outcome Measures:
  • The change in macular leakage on fluorescein angiography from baseline [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    To qualitatively assess the change in macular leakage on fluorescein angiography from baseline to 6 months for each treatment arm.

  • The change in mean macular sensitivity on microperimetry from baseline [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    To assess the change in macular sensitivity on microperimetry from baseline to 6 months for each treatment arm.

  • The change in mean central amplitude on multi-focal ERG from baseline. [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    To assess the change in mean central amplitude on multi-focal ERG from baseline to 6 months for each treatment arm.

Detailed Description:

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Presence of NPDR or PDR as confirmed by fluorescein angiography
  • Prior treatment with >= 2 intravitreal anti-VEGF injections but no treatment in last 4 weeks
  • < 0.1 LogOCT decrease in macular edema on high resolution OCT between initial visit and following treatment with >= 2 intravitreal anti-VEGF injections
  • Age 18 years or older
  • ETDRS Visual acuity between 3 and 78 letters (approximate Snellen equivalent of 20/25 to 20/800)
  • Ability to provide written informed consent
  • Capable of complying with study protocol.

Exclusion Criteria:

  • Intraocular injection of steroid medication within prior 3 months
  • Evidence of significant geographic atrophy on fluorescein angiography in the opinion of the treating physician
  • Concurrent ocular disease (wet AMD, significant ERM, etc) that would limit visual acuity in the opinion of the treating physician
  • Prior vitrectomy surgery
  • Use of systemic steroids (eg, oral, intravenous, intramuscular, epidural, rectal, or extensive dermal) within 1 month prior to day 1.
  • Known history of IOP elevation in response to steroid treatment in either eye that resulted in any of the following: a) = 10 mm Hg increase in IOP in response to steroid injection, or b) IOP = 25 mm Hg and required 2 or more anti-glaucoma medications to keep IOP below 21 mm Hg.
  • Patients who are pregnant.
  • Unwilling or unable to follow or comply with all study related procedures
