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

    March 2010

Study Arms (1)

Ranibizumab

EXPERIMENTAL

Ranibizumab 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.

Drug: ranibizumab

Interventions

Ranibizumab 0.5mg at baseline and then again at 30 days and/or 60 days after PRP as deemed appropriate by the Investigator.

Also known as: Lucentis
Ranibizumab

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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
