• To assess the long-term safety and efficacy of the 0.19-mg fluocinolone acetonide (FAc) intravitreal implant (Iluvien; Alimera Sciences, Inc) in patients with diabetic macular edema (DME). Three-year, phase 4, nonrandomized, open-label observational study. Patients with DME who previously received corticosteroid treatment without a clinically significant rise in intraocular pressure (IOP; all eyes, n = 202 eyes of 159 patients; 36-month completion, n = 94 eyes). A prospective, observational study in which patients received a 0.19-mg FAc intravitreal implant at baseline and then were observed for safety-, visual-, anatomic-, and treatment burden-related outcomes for up to 36 months. Primary safety outcomes included changes in IOP and interventions to manage IOP elevations. Secondary outcomes included changes in best-corrected visual acuity (BCVA), central subfield thickness (CST), and adjunctive DME treatment frequency RESULTS: At 36 months after FAc implantation, study eyes showed a mean CST change of -60.69 μm (P < 0.0001) and a mean BCVA change of +3.61 letters (P = 0.0222) compared with baseline. Overall median treatment frequency decreased from 3.4 treatments/year in the 36 months before FAc implantation to 1 treatment/year in the 36 months after FAc implant, a treatment burden reduction of 70.5%. Furthermore, among the group that completed 36 months of treatment (n = 94 eyes), 25.53% of eyes remained rescue free through 36 months. Mean IOP remained stable throughout the study, and IOP increases to more than 30 mmHg occurred in 10.89% of eyes. Intraocular pressure-related procedures were infrequent, with a surgical rate of 2.97%, with 1.49% attributable to steroid use (vs. surgeries attributable primarily to neovascular glaucoma). In addition, an IOP response of < 25 mmHg after the steroid challenge predicted that 96.92% of eyes would have a similar outcome to 0.19-mg FAc implant at the last visit. Intraocular pressure increases that did occur were manageable with standard treatments (n = 202 eyes). In patients with DME, the 0.19-mg FAc implant provided improved visual outcomes and reduced treatment burden compared with previous treatments while maintaining a favorable safety profile.
