Three-year results from the Retro-IDEAL study: Real-world data from diabetic macular edema (DME) patients treated with ILUVIEN ? (0.19?mg fluocinolone acetonide implant)

摘要

Introduction: The Retro-IDEAL (ILUVIEN Implant for chronic DiabEtic MAcuLar edema) study is a retrospective study designed to assess real-world outcomes achieved with the ILUVIEN? (0.19 mg fluocinolone acetonide (FAc)) in patients with chronic diabetic macular edema (DME) in clinical practices in Germany. Methods: This study was conducted across 16 sites in Germany and involved 81 eyes (63 patients) with persistent or recurrent DME and a prior suboptimal response to a first-line intravitreal therapy (primarily anti-VEGF intravitreal therapies). Results: Patients were followed-up for 30.8?±?11.3?months (mean?±?standard deviation) and had a mean age of 68.0?±?10.4 years. Best-recorded visual acuity (BRVA) improved by +5.5 letters at month 9 (P???0.005, n=56; from a baseline of 49 letters) and this was maintained through to month 30 (P???0.05, n?=?42). There was a concurrent improvement in central macular thickness with a reduction from 502?μm at baseline to 338?μm at year 1 (P???0.0001, n?=?43). This effect was sustained to year 3 (i.e. 318?μm; P???0.0001, n?=?29). Mean intraocular pressure (IOP) remained constant between baseline and year 3 with a peak change of 1.9?mm?Hg occurring at year 1. Elevated IOP was observed in a similar percentage of patients prior to (22.2% of cases) and following (27.2%) treatment with the FAc implant. In the majority of cases, these elevations were managed effectively with IOP medications. Conclusions: Despite substantial amounts of prior intravitreal treatments – primarily with anti–vascular endothelial growth factor (VEGF) drugs – this real-world study showed that sustained structural and functional improvements can last for up to 3?years with a single FAc implant.
