  Purpose

The purpose of this study is to compare ranibizumab injection to hemodilution at the early phase of Central Retinal Vein Occlusion (CRVO) and to determine if the combination of both treatments may have a synergic effect.

Primary Outcome Measures:
  • Change in visual acuity [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    Change in best-corrected visual acuity (ETDRS chart) between baseline and 6 months


Secondary Outcome Measures:
  • Gain in visual acuity of 2 ETDRS-lines or more [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Number of patients who gained 2 lines or more between baseline and the 6-month visit


Estimated Enrollment: 45
Study Start Date: January 2010
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: ranibizumab
patients in this arm receive 3 monthly injection of ranibizumab
Drug: ranibizumab
3 monthly intravitreous injection as soon as possible after the inclusion
Other Name: Lucentis
Active Comparator: Hemodilution
hemodilution using erythrocytapheresis is performed as early as possible after inclusion, in order to lessen hematocrit level (target hematocrit of 35%)
Procedure: hemodilution
hemodilution using erythrocytapheresis - target hematocrit: 35% - as soon as possible after the inclusion
Active Comparator: ranibizumab and hemodilution
patients receive both treatments
Drug: ranibizumab
3 monthly intravitreous injection as soon as possible after the inclusion
Other Name: Lucentis
Procedure: hemodilution
hemodilution using erythrocytapheresis - target hematocrit: 35% - as soon as possible after the inclusion

Detailed Description:

Patients with recent-onset CRVO (lasting for less than 1 month)are randomly assigned to one of 3 groups: hemodilution using erythrocytapheresis alone, 3 monthly injection of ranibizumab alone, or both.

Patients are followed monthly during the 6-month study.

  Eligibility

Ages Eligible for Study:   18 Years to 75 Years
