Outcome Measures
Primary Outcomes (1)
Mean Change From Pre-PRP Best Corrected Visual Acuity (BCVA) at 3 Months as Expressed as an Early Treatment Diabetic Retinopathy Study (ETDRS) Score (Number of Letters Correctly Read.)
No outcome measures were obtained for this study. Study was terminated by Investigator/Sponsor due to low enrollment. The data was not formally analyzed but reviewed only on a case study basis.
March 2010
Secondary Outcomes (2)
Mean Change From Pre-PRP Optical Coherence Tomography (OCT) in Central Foveal Thickness and Macular Volume as Assessed by OCT at 1, 2 and 3 Months.
March 2010
Percentage of Patients That Maintain Pre-PRP Visual Acuity at the 3 Month Time Point

Study Arms (1)
Ranibizumab
EXPERIMENTALRanibizumab is being used off-label to test the safety and efficacy of its use in Diabetic Macular Edema post panretinal photocoagulation. Ranibizumab 0.5mg at baseline and then again at 30 days and/or 60 days after PRP as deemed appropriate by the Investigator.
Interventions
Ranibizumab 0.5mg at baseline and then again at 30 days and/or 60 days after PRP as deemed appropriate by the Investigator.
Eligibility Criteria
You may qualify if:
- Pre-PRP protocol refraction, fluorescein angiography, and optical coherence tomography AND 7-14 day post-PRP OCT
- Ability to provide written informed consent and comply with study assessments for the full duration of the study
- Age 21 years or older
- Previously untreated PDR patients with high risk characteristics who develop edema within 7-14 days post PRP therapy. This edema, determined by a masked investigator, will be characterized as either increased foveal thickness (\>10% increase from pre-PRP foveal thickness), and/or increased macular volume on OCT (\>10% increase from pre-PRP macular volume).
You may not qualify if:
- Pregnancy (positive pregnancy test) prior to enrollment in the study
- 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
- Pre-PRP clinically significant diabetic macular edema (CSME) that would make the patient eligible for macular laser prior to PRP
- Neovascularization of the iris or neovascular glaucoma
- Increased central foveal thickness for any other reason
- Concurrent macular diseases that could confound the results of this study
- Prior vitrectomy in the study eye
- Prior treatment with intravitreal injection including pegaptanib sodium, ranibizumab, bevacizumab or triamcinolone acetonide
