Inclusion Criteria

2. Diagnosis of diabetes mellitus (type 1 or type 2) as defined by the World Health Organization/International Diabetes Federation (Report of a WHO/IDF consultation, 2006)
- Fasting plasma glucose level = 7.0 mmol/L (126 mg/dL) or
- Plasma glucose = 11.1 mmol/L (200 mg/dL) 2 hours after a 75 g oral glucose load as in a glucose tolerance test.

3. Presence of macular edema associated with diabetic retinopathy defined as macular thickening by optical coherence tomography (OCT) assessed by the investigator in the study eye with the following characteristics:
- involving the center of the macula (fovea)
- VA decrease attributable to macular edema

4. BCVA score = 34 and = 70 letters (approximately 20/200 to 20/40 on the Snellen scale) using the Early Treatment Diabetic Retinopathy Study (ETDRS) method in the study eye at the screening visit.

5. Study eye mean retinal thickness by spectral domain OCT in the 1 mm central macular subfield of = 300 µm with Spectralis (Heidelberg) or 275 µm with Cirrus (Zeiss) as determined by the investigator at the screening visit.

6. (Both Eyes) Media clarity, pupillary dilation, and patient cooperation sufficient for all study procedures.

7. Written informed consent has been obtained in accordance with state and country privacy requirements, where applicable.

Exclusion Criteria

Systemic conditions or treatments
1. History of disease, metabolic dysfunction, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of the investigational drug, might affect the interpretation of study results or render the patient at high risk from treatment complications.

2. HbA1c (glycated hemoglobin) >12% at baseline.

3. Untreated diabetes mellitus or initiation of oral anti-diabetic medication or insulin within 4 months prior to baseline or anticipated change of anti-diabetic medications during the 1-year study participation.

4. Renal failure requiring hemodialysis or peritoneal dialysis within 6 months prior to baseline or anticipated need for hemodialysis or peritoneal dialysis at any time during the study or adjusted glomerular filtration rate < 50 mL/min.

5. Use of systemic (eg, oral, intravenous, intramuscular, epidural, rectal, or extensive dermal) corticosteroids within 1 month prior to screening.

6. Uncontrolled systemic disease

Ocular concomitant conditions/disease
7. Any current or history of ocular disease in the study eye, other than DME that in the opinion of the investigator may confound assessment of the macula or affect central vision (for example: exudative age-related macular degeneration [AMD], geographic atrophy, macular edema due to retinal vein occlusion, uveitis, angioid streaks, histoplasmosis, active or inactive cytomegalovirus, pathological myopia, retinal detachment, macular traction, macular fibrosis or scarring, macular hole, significant cataract).

8. Increased intraocular pressure (IOP = 22 mmHg) at screening or day 1, or diagnosis of glaucoma.

9. Any active ocular inflammation or ocular infection (ie, bacterial, viral, parasitic, or fungal) in either eye at the screening visit.

10. Aphakia in the study eye or break in the posterior capsule in the study eye, unless it is a small break resulted from a YAG laser posterior capsulotomy in association with prior posterior intraocular lens implantation

11. Anticipated need for ocular surgery in the study eye during the 1-year study participation.

12. Active proliferative diabetic retinopathy and/or rubeosis.

13. BCVA score < 34 letters in fellow eye.

Ocular treatment
14. Laser photocoagulation to the study eye within 3 months prior to screening.

15. Use of anti-VEGF treatment in study eye within 3 months prior to screening or use of systemic anti-VEGF within 6 months prior to screening
16. Use of intravitreal triamcinolone within 6 months prior to screening.

17. Use of topical intraocular, intravitreal (except triamcinolone, see above) or periocular corticosteroids within 3 months prior to screening in the study eye or ocular conditions in the study eye that require chronic concomitant therapy with topical, local ocular or systemically administered corticosteroids.
