Reporting Groups
  Description
Sham Injection/Ranibizumab 0.5 mg Patients received a sham intravitreal injection monthly for 24 months. Patients who had not discontinued treatment by Month 24 could choose to receive ranibizumab 0.5 mg monthly administered intravitreally for the subsequent 12 months. Patients who had not discontinued treatment by Month 36 could enter the open-label extension phase to receive ranibizumab 0.5 mg as needed (pro re nata [PRN]) for up to 24 additional months.
Ranibizumab 0.3 mg Patients received ranibizumab 0.3 mg monthly administered intravitreally for 36 months. Patients who had not discontinued treatment by Month 36 could enter the open-label extension phase to receive ranibizumab 0.5 mg as needed (pro re nata [PRN]) for up to 24 additional months.
Ranibizumab 0.5 mg Patients received ranibizumab 0.5 mg monthly administered intravitreally for 36 months. Patients who had not discontinued treatment by Month 36 could enter the open-label extension phase to receive ranibizumab 0.5 mg as needed (pro re nata [PRN]) for up to 24 additional months.
