This study evaluates long-term safety in patients with macular edema due to Retinal Vein Occlusion (RVO) originally enrolled in the BRAVO & CRUISE trials and subsequently followed in the HORIZON extension trial.

Primary Outcome Measures:
  • Incidence of Serious Adverse Events. [ Time Frame: 24 mos ] [ Designated as safety issue: Yes ]
    Record the serious adverse events, both ocular and non-ocular to gather long-term safety data.

Secondary Outcome Measures:
  • Mean Changes in Visual Acuity [ Time Frame: 24 mos from study baseline ] [ Designated as safety issue: No ]
    Mean changes in visual acuity. Visual acuity is measured using standard ETDRS (Early Treatment Diabetic Retinopathy Study) charts which measure visual acuity in terms of letters( ETDRS Letters) read at a distance of 4 meters away from the chart. The ETDRS letters Score can be from 0 to 100, with 0 representing poor vision and 100 representing best vision.

  • Mean Change in Retinal Thickness [ Time Frame: 24 mos from study baseline ] [ Designated as safety issue: No ]
    Mean change in retinal thickness as measured by OCT (Optical Coherence Tomography).

Enrollment: 66

Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ranibizumab as needed
Intravitreal ranibizumab, .5mg dose, PRN but not less than 21 days apart; with optional peripheral laser to areas of non-perfusion.
Drug: ranibizumab
Intravitreal ranibizumab, .5mg dose, PRN but not less than 21 days apart.
Other Name: RBZ, lucentis
Other: Peripheral Laser
Areas of nonperfusion identified on wide field angiograms will receive laser, if the patient is continuing to require ranibizumab injections.
Other Name: Laser

Detailed Description:
There is strong evidence that ranibizumab provides benefit in subjects with macular edema due to RVO; however, some subjects required continued injections for years to maintain those benefits. It is likely that such subjects have continued production of VEGF (Vascular Endothelial Growth Factor) from areas of nonperfused retina in the periphery. One strategy is to perform scatter photocoagulation to areas of nonperfusion to reduce continued production of VEGF, but it is important to know if visual benefits are maintained when this is done, because if it is not, it would be better to continue intermittent injections of ranibizumab.
