Eligibility Criteria

Inclusion Criteria

  • Subjects will be eligible if the following criteria are met:
  • Age \> 18 years
  • Diagnosis of diabetes mellitus (type 1 or 2)
  • Residual edema as determined by mean foveal thickness on Spectralis OCT (optical coherence tomography) \> 300 microns and leakage seen on FA at baseline
  • Clinical evidence of retinal thickening due to macular edema involving the center of the macula, associated with diabetic retinopathy.
  • Previous history of at least 3-5 or more consecutive 1.25 mg of intravitreal bevacizumab injections for the treatment of diabetic macular edema (consecutive injections administered no more than 6 weeks apart).
  • BCVA of 20/32-20/400 using Early Treatment Diabetic Retinopathy Study (ETDRS)
  • Media clarity, pupillary dilation and patient cooperation sufficient to allow OCT testing and retinal photography

Exclusion Criteria

  • Pregnancy (positive pregnancy test) or known to be pregnant; also pre-menopausal women not using adequate contraception.
  • Participation in another ocular investigation or trial simultaneously.
  • Systemic use of anti-VEGF within 3 months prior to day
  • Blood pressure \> 180/110 (systolic above 180 OR diastolic above 110)
  • Any condition that, in the opinion of the investigator, would preclude participation in the study (e.g. chronic alcoholism, drug abuse).
  • Evidence of vitreoretinal interface abnormality after ocular exam or OCT that may be contributing to the macular edema.
  • An eye that, in the investigator's opinion, has no chance of improving in visual acuity following resolution of macular edema (e.g. presence of subretinal fibrosis, ischemic maculopathy or geographic atrophy).
  • Presence of another ocular condition that may affect the visual acuity or macular edema during the course of the study (e.g. Age-related Macular Degeneration, uveitis, Irvine-Gass).
  • Evidence of active neovascularization of the iris or retina.
  • Evidence of central atrophy or fibrosis in the study eye.

Arms & Interventions

Patients with 3-5 consecutive Avastin injections

These patients will receive 0.5 mg of intravitreal Ranibizumab monthly for 6 months.

Intervention: injection of 0.5 mg of Intravitreal Ranibizumab

Patients with 6 or more consecutive injections of Bevacizumab

Patients will receive 0.5 mg of intravitreal Ranibizumab during the first 6 months.

Intervention: injection of 0.5 mg of Intravitreal Ranibizumab

Outcomes

Primary Outcomes

Proportion of subjects with resolution of diabetic macular edema compared to baseline as determined by mean foveal thickness on Spectralis < 300 microns.

Time Frame: 6 months

Secondary Outcomes

  • Evaluate the main change in BCVA (best corrected visual acuity) score over time(6-12 months)
