REtinal Vein OccLUsion Treatment With Scatter Laser Guided by UWFA in combiNAtion With Ranibizumab Study

Completed · Phase 2

Conditions studied: Macular Edema, Branch Retinal Vein Occlusion

In brief

Branch retinal vein occlusion is a leading cause of vision loss. Treatment with ranibizumab (vascular endothelial growth factor (VEGF) inhibitor) on a monthly basis has been associated with improved vision results. There is a subgroup of patients with peripheral nonperfusion on ultrawidefield angiography that appears to be more dependent on anti-VEGF treatment. In this trial the investigators compare the gold standard of monthly ranibizumab injections with ranibizumab + peripheral scatter laser to the areas of nonperfusion on angiography. Each group will have monthly injections for the first six months, then as needed by either visual acuity decrease or increased retinal thickness for the subsequent six months. The primary outcome is visual acuity. Secondary outcomes are reduction in optical coherence tomography, and number of ranibizumab injections

You may qualify if…

• Subjects will be eligible if the following criteria are met:

• Age > 18 years
• Disease related considerations:
• Study eye with macular edema secondary to branch retinal vein occlusion characterized by:
• Fovea-involved macular edema of less than 12 months peripheral nonperfusion defined as at least 5 disc areas of contiguous nonperfusion on ultra-widefield fluorescein angiography absence of macular traction on clinical exam, UWFA, and OCT.
• Study eye with best corrected visual acuity between 20/40 (≤ 73 letters on ETDRS chart) and 20/320 (≥ 19 letters on ETDRS chart)
• Other considerations
• Patient able to complete all study visits

You may not qualify if…

• Subjects who meet any of the following criteria will be excluded from this study:
• Pregnancy (positive pregnancy test) or lactation. Premenopausal women not using adequate contraception. The following are considered effective means of contraception: surgical sterilization or use of oral contraceptives, barrier contraception with either a condom or diaphragm in conjunction with spermicidal gel, an IUD, or contraceptive hormone implant or patch.
• Prior 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
• Therapy with intravitreal triamcinolone, pegaptanib, ranibizumab, or bevacizumab within the previous 3 months
• Previous macular or panretinal scatter laser photocoagulation
• Previous pars plana vitrectomy
• Visually-significant significant cataracts as primary reason for vision loss
• Myocardial infarction or cerebrovascular accident within 6 months
