  Purpose

Angiogenesis plays a key role in the development of choroidal neovascularizations (CNV) in age-related macular degeneration. Vascular endothelial growth factor (VEGF) is the most important factor involved in this angiogenetic processes in the eye. This forms the basis for new therapeutic interventions in exudative AMD. Currently two drugs have been approved by the FDA and one drug is used off-label. All these drugs are administered intravitreally. The present study aims to directly compare the effects ranibizumab and bevacizumab in a randomized controlled study in patients with neovascular AMD.

  Eligibility

Ages Eligible for Study:   50 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Age ≥ 50 years
  • Active primary or recurrent subfoveal lesion with CNV secondary to AMD

Exclusion Criteria:

Prior treatment with any intravitreal drug in the study eye

  • Prior treatment with verteporfin photodynamic therapy in the study eye
  • Prior treatment with systemic bevacizumab
  • Prior treatment with any intravitreal durg or verteprofin photodynamic therapy in the nonstudy eye within the 3 moths before the study entry
  • Laser photocoagulation within 1 month before study entry in the study eye
  • Previous participation in any clinical trial within 1 month before the entry of the study
  • Subfoveal fibrosis or atrophy in the study eye
  • CNV in either of the two eye due to causes other than AMD such as histoplasmosis or pathologica myopia
  • Retinal pigment epithelial tear involving the macula in the study eye
  • Any concurrent intraocular condition in the study eye that could either require medical or surgical intervention during the 12 month study period or that could contribute to a loss of best corrected visual acuity over the 12 months study period (e.g. diabetic retinopathy, cataract, uncontrolled glaucoma). The decision on exclusion is to be based on the opinion of the local principal investigator.
  • Active intraocular inflammation
  • Vitreous hemorrhage in the study eye
