Steroids and DME Scott E. Pautler, M.D. Associate Clinical Professor of Ophthalmology University of South Florida Tampa, FL Case Presentation • 71 year old woman with type 2 diabetes for 12 years with gradually decreasing vision OU • Visual acuity: R-20/50, L-20/125 • Slit lamp: 2+ nuclear sclerosis • IOP 18 OU • Fundus: DME OU; moderate NPDR OU 3/23/2009 Right Eye Treatments: Focal – 2 IVK – 10 CE/IOL Left Eye Treatments: Focal – 3 IVK – 13 CE/IOL VTX/ILM peel PRP -2 2/5/2014 Visual Acuity and OCT Outcomes Date Eye CSMT (µ) VA 3/23/2009 Right 398 20/50 Left 397 20/125 Right 267 20/20 Left 490 20/100 2/5/2014 Steroid Mechanism of Action • Decrease VEGF production • Widespread anti-inflammatory effects • More rapid onset and more profound initial effect on edema than anti-VEGF agents • Adverse effects: cataract, glaucoma Pre-injection IVTA 1 month later Steroid Agents Triamcinolone vs Focal/Grid Laser • DRCR Protocol B: 840 eyes • Three-year results • Problems: 79% of eyes were phakic and IVTA dosing interval was ≥ 4 months Treatment Mean BCVA gains Δ CSMT In microns Cataract Surgery Glaucoma Surgery Glaucoma Drops Focal/Grid +5 letters -158 0 0 3% IVTA 1 mg 0 letters -103 46% 0 2% IVTA 4 mg 0 letters -114 83% 4 (1.6%) 12% Combination IVTA + Focal/Grid Laser (FGL) • DRCR Protocol I: Pseudophakic eyes (206) – Two-year results Treatment Mean Δ BCVA (letters) Mean Δ CSMT (μ) IVTA 4 mg + FGL +8 -128 Sham + FGL +5 -145 IVR + Prompt FGL +5 -126 IVR + Deferred FGL +9 -148 Triamcinolone Options Triamcinolone FDA approve d Crystal Size Dissolution Cost Profile Pseudo Endophth Preserved No 18.86 μ Faster $9.32 ≤7% PreservativeFree Yes 11.51 μ Slower $157.58 ≤1% Dexamethasone Implant • Recently approved by FDA for DME Bio-erodible Duration ≤6 months • Ozurdex MEAD Study Group 2014: – 1048 eyes; 20/50-20/200; CRT ≥300μ; 3-year Mean CRT (μ) Cataract Glaucoma Surgery Sham injection 12% -42 20% 0% Dex 0.35 mg 18.4% -108 64% 0.3% Dex 0.70 mg 22.2% -112 68% 0.6% Treatment ≥15 letter improvement Dexamethasone Implant • BEVORDEX Study (AAO subspecialty meeting) – 1-year result of RCT – bevacizumab vs dexamethasone – Dexamethasone superior functional and anatomic outcomes in pseudophakic eyes – Mean number of injections: • 3.7 Dexamethasone injections • 8.6 bevacizumab injections Fluocinolone Implant • Recently approved by FDA for DME Non-responders; Duration ≤3 years • FAME Study 2012: – 953 eyes; failed FLT; 20/50-20/400; CRT ≥250μ; 3-year study Mean CRT (μ) Cataract Glaucoma Surgery Sham injection* 21% NG 51% 0.5% Fluo 0.2 μg/d 33% NG 82% 4.8% Fluo 0.5 μg/d 32% NG 89% 8.1% Treatment ≥15 letter improvement *Rescue treatment with focal laser and/or anti-VEGF occurred more often in Sham Steroids and IOP • Risk Factors: Glaucoma, OHT, steroid response, young age, higher loading dose Steroid Agent ≥10mm (values adjusted over by control group) baseline ≥25mm at any exam Any IOP meds Surgery For IOP Attrition by 3 years Triamcinolone 1 mg 18% (14%) - 2% (0%) 0% (0%) 64% Triamcinolone 4 mg 33% (29%) - 12% (9%) 4% (4%) 64% Dexamethasone Impl 0.70 mg 28% (24%) 32% (28%) 42% (33%) 1% (1%) 42% Fluocinolone Impl 0.19 mg 34% (24%) 20% (16%) 38% (24%) 5% (4%) 30% Case Selection • Pseudophakic, Non-Glaucoma/Suspect Eyes – AC IOL: consider avoiding an implant – Post vitrectomy: consider avoiding IVTA (storm) – Prior glaucoma surgery offers limited protection against steroid-IOP response Case Selection • DME resistant to anti-VEGF/laser* • Macula-threatening exudates (BEVORDEX) • One-time use for DME prior to surgery: – PRP laser – cataract surgery * Fluocinolone implant relatively more effective in chronic edema (>3yrs) Steroid Selection • Triamcinolone – Less expensive (Kenalog®) – More frequent injection – Greater peak/trough effect • Steroid implant – More expensive – Fewer injections – Better pharmacokinetics (Iluvien®>Ozurdex®) Thank you Scott E.
