- Current regular use of insulin for the treatment of diabetes mellitus OR
- Current regular use of oral anti-hyperglycemia agents for the treatment of diabetes OR
- Documented diabetes by WHO criteria
- Patients must have ETDRS best corrected visual acuity of 69 to 24 letters (20/40 to 20/320 Snellen Equivalent) in the study eye.
- Patients must have a mean retinal thickness on OCT ≥ 250 microns in the central subfield.
Exclusion
- Patients with a history of chronic renal failure requiring dialysis or kidney transplant.
- A condition that, in the opinion of the investigator, would preclude participation in the study (e.g., unstable medical status including blood pressure and glycemic control), including:
- Patients in poor glycemic control who, within the last 4 months, initiated intensive insulin treatment (a pump or multiple daily injections) or plan to do so in the next 4 months should not be enrolled.
- Patients with HbA1C \> 10%OR
- Patients with systolic blood pressure greater than 170 mmHg and/or diastolic blood pressure greater than 100 mmHg (Note: If blood pressure is brought below 170/100 mmHg by anti-hypertensive treatment, patient can become eligible).
- Past panretinal photocoagulation (PRP) for diabetes within 12 weeks of screening or PRP expected to be needed in the next three months in the study eye.
- Focal laser therapy to the retina of the study eye within 12 weeks of screening.
- Any intraocular surgery or ocular laser procedures in the study eye within 12 weeks of screening.
- Participation in an investigational trial within 30 days of study entry that involved treatment with any drug that has not received regulatory approval at the time of study entry.
