Summary
The primary objective of the study is to assess the ocular and systemic adverse events of ranibizumab (Lucentis)for DME (diabetic macular edema) following previous treatment with intravitreal bevacizumab (Avastin).

- Panretinal photocoagulation treatment within 3 months of study entry in the study eye.
- Prior vitrectomy in the study eye
- History of retinal detachment in the study eye
- Prior trabeculectomy or other filtration surgery in the study eye
- Active intraocular inflammation in either eye
- Active ocular or periocular infection in either eye
- Active scleritis or episcleritis in either eye
- History of any other retinal vascular disease (e.g., retinal vein occlusion, retinal artery occlusion) in the study eye.
- Coexistent retinal disease other than diabetic retinopathy (e.g., AMD (age related macular degeneration), inherited retinal disease) in the study eye.
- Intraocular surgery within 3 months of study entry in the study eye.
- History of corneal transplant or corneal dystrophy in the study eye.
- Significant media opacities in study eye which may interfere with visual acuity in the study eye.
- Participation as a subject in any clinical study within 3 months of study entry.
- History of allergy to topical iodine
- Any other condition that the investigator believes would pose a significant hazard to the subject if the investigational therapy were initiated
- Participation in another simultaneous medical investigation or trial
