Summary 62 yo WM presents sent from optometrist for fundus appearance of BRVO 5-6 months after sudden blurred vision overnight OS. BCVA 20/30 initially, 20/25 15 days later. Represents a chronic superotemporal BRVO with retinal ischemia and vascular collaterlization OS.
Branch Retinal Vein Occlusion Turbulence in vein caused by atherosclerosis in crossing artery Thrombus formation at arteriovenous crossing point Varying severity of intraretinal hemorrhage, retinal edema, dilated and tortuous veins, +/- CW spots Most often superotemporal
Branch Retinal Vein Occlusion Photo Examples http://www.eye.uci.edu/retinavitreous.html http://en.wikipedia.org/wiki/branch_retinal_vein_occlusion
Risk Factors Described by The Eye Disease Case-Control Study Group, 1993 Hypertension Cardiovascular disease Open angle glaucoma High body mass index NOT diabetes mellitus
2014 Almost 500,000 enrollees, 2283 with BRVOs Increased hazard of developing BRVO in pts with: HTN alone HTN and metabolic syndrome components DM, HLD DM with END-ORGAN DAMAGE Hx of CVA
Branch Retinal Vein Occlusion Grid & Scatter Laser Pars plana vitrectomy Intravitreal Steroids Intravitreal anti-vegf Treatment Options
Branch Vein Occlusion Study (BVOS) Started data 1977, published in 1984, 1986 Argon grid laser photocoagulation improved visual outcome significantly in eyes with BRVO with decreased VA to 20/40 20/200 due to macular edema not macular ischemia Scatter argon laser photocoagulation decreased risk of neovascularization from 22% to 12% in eyes with recent BRVO involving at least 5 DD of retinal non-perfusion Scatter laser also decreased risk of vitreous hemorrhage from 60% to 30% in recent BRVO eyes with neovascularization
Branch Vein Occlusion Study (BVOS) Vision Outcomes Eyes treated with macular laser more likely to be 20/40 or better at 3 years follow-up Mean VA improved 1.3 ETDRS lines (vs. 0.2 lines) Mean treated VA: 20/30 20/50 Mean untreated VA: 20/70
Branch Retinal Vein Occlusion Treatment justification for this patient: No macular ischemia with VA 20/25 Macular edema, mostly temporally with VA 20/25 No neovascularization Therefore observed at this point Any other treatment options recommended?
Branch Retinal Vein Occlusion Current Treatment Options Intravitreal steroids: SCORE study (2009) Intravitreal dexamethasone implant: OZURDEX GENEVA study Pars plana vitrectomy for non-resolving VH or for RD
Branch Retinal Vein Occlusion SCORE Study Standard Care Vs Corticosteroid for Retinal Vein Occlusion (2009) Intravitreal triamcinolone for treatment of macular edema in BRVO/CRVO BRVO arm: 1 mg vs 4 mg vs grid laser 26%, 27%, 29% respectively gained 3+ lines
Branch Retinal Vein Occlusion OZURDEX GENEVA Study (2010) Intravitreal dexamethasone implant for treatment of macular edema in BRVO/CRVO 0.7 mg vs 0.35 mg vs sham 26% vs 19% vs 17% respectively of 15+ letter gain
Branch Retinal Vein Occlusion BRAVO Study Branch Retinal Vein Occlusion Study (2010) Ranibizumab to eyes with macular edema 0.5 mg vs 0.3 mg vs sham 61.1%, 55.2%, and 28.8% respectively gained 15+ ETDRS letters at 6 months
Branch Retinal Vein Occlusion Prognosis Related to extent of capillary damage and retinal ischemia in macula Can try to assess with FA Integrity of parafoveal capillaries is the important prognostic factor for VA Macular edema, retinal hemorrhage, or perifoveal retinal capillary occlusion can reduce vision 50-60% of pts w/all types of BRVO maintain VA 20/40 or better after 1 year
2014 Retrospective chart review looked at what people are doing 885 BRVO pts treated with bevacizumab also looked at CRVO & DME pts Too few ranibizumab-treated pts for meaningful analysis 42% of BRVO pts received additional laser or IVTA therapy Patients treated with bevacizumab were monitored less frequently and received fewer injections than patients in major clinical trials of ranibizumab.
