RESUMO
OBJECTIVE: Fluocinolone acetonide is a valid alternative treatment for patients with chronic diabetic macular edema (DME) with poor response to anti-vascular endothelial growth factor (VEGF) therapy. The purpose of this study is to report the efficacy and safety of ILUVIEN® implant in pseudophakic eyes with persistent DME. PATIENTS AND METHODS: This is a single-centre pilot-study of 8 patients with persistent DME treated with the ILUVIEN implant, despite previous anti-vascular endothelial growth factor and/or steroid treatment. Best-corrected visual acuity (BCVA), optical coherence tomography (OCT) central retinal thickness, intraocular pressure (IOP) and microperimetric data were evaluated at baseline and month 1, 3 and 6 post treatment. RESULTS: All data are presented as mean and standard deviation. At baseline, 1, 3 and 6 months, we had BCVA of 0.26±0.22, 0.38±0.27, 0.48±0.27 and 0.46±0.24; IOP of 15.00±2.67, 15.50±3.16, 14.88±2.42 and 15.63±2.67 mmHg; macular thickness of 652±231, 487±278, 475±287 and 413±211 µm; macular sensitivity of 6.83±4.20, 6.13±3.72, 7.68±3.40 and 7.71±3.33 dB; bivariate contour elliptic area (BCEA) 95.4% 3.8±3.42, 6.06±10.06, 3.05±2.46 and 2.59±2.19°2. CONCLUSIONS: According to the results of our study, fluocinolone acetonide (FAc) is a valid therapy option despite some limitations. It has been evidenced that FAc is more effective in patients with mild central macular thickening, while in those with modest to severe central macular thickness (CMT), different therapy strategies should be considered.
