- Real-world retrospective comparison of 0.19 mg fluocinolone acetonide and 0.7 mg dexamethasone intravitreal implants for the treatment of diabetic macular edema in vitrectomized eyesPublication . Coelho, João; Malheiro, Luisa; Melo Beirão, João; Meireles, Angelina; Pessoa, BernardetePurpose: The aim of this study was to evaluate the long-term real-world effectiveness of FAc and DEX implants in vitrectomized DME eyes in a real-world setting. Methods: This was a non-interventional, retrospective, comparative study of 46 vitrectomized eyes in 33 patients with persistent or recurrent DME quantified best-corrected visual acuity (BCVA), central foveal thickness (CFT) and intraocular pressure (IOP) over up to 37 months. Results: Both FAc and DEX treatment led to statistically and clinically significant improvements in BCVA and CFT. FAc >10-letter improvement on the Early Treatment Diabetic Retinopathy Study [ETDRS] chart over months 3-24 and a sustained ~200 µm CFT reduction over months 1-24; DEX: >5-letter improvement on the ETDRS chart at months 1 and 3 and >100 µm CFT reduction at month 1. FAc demonstrated sustained, stable and predictable effects on BCVA and CFT over 24 months and also improved BCVA and decreased CFT in a cohort of DME eyes that was refractory to DEX over 6 months. Conclusion: This real-world study demonstrates long-term effectiveness of FAc in vitrectomized DME eyes and sustained effectiveness in DME eyes that did not respond to DEX therapy.
- Fluocinolone Acetonide 0.19 mg Implant in Patients with Cystoid Macular Edema Due To Irvine–Gass SyndromePublication . Marques, Joao Heitor; Abreu, Ana Carolina; Silva, Nisa; Meireles, Angelina; Pessoa, Bernardete; Beirão, JoãoBackground: Cystoid macular edema (CME) due to Irvine-Gass syndrome (IGS) is one of the common causes of painless visual impairment post-cataract extraction. The treatment of recurrent cases remains unstandardized. Objective: To evaluate the effectiveness and safety of fluocinolone acetonide intravitreal implant (0.2 µg/day; ILUVIEN®) in the off-label treatment of recurrent CME due to IGS. Methods: Retrospective 36-month case series in the Ophthalmology Department of Centro Hospitalar Universitário do Porto, Portugal. Consecutive eyes of patients with recurrent cystoid macular edema due to Irvine-Gass syndrome who underwent a single intravitreal injection of fluocinolone acetonide intravitreal implant were included. Best-corrected visual acuity (logMAR), central macular thickness (µm) and safety (intraocular pressure, mmHg) at baseline and at 6, 12, 24 and 36 months post-administration of the fluocinolone acetonide intravitreal implant were recorded. Results: Five eyes from three patients were included. The duration of cystoid macular edema was 67.8±25.9 months and all five eyes received more than 2 intravitreal injections of a corticosteroid (triamcinolone and/or dexamethasone implant) prior to fluocinolone acetonide intravitreal implantation. At baseline (median - interquartile range), best-corrected visual acuity was 0.3-0.3; central macular thickness was 492.0-38.0; and intraocular pressure was 16.0-0. By Month 36, best-corrected visual acuity was 0.4 -0.3; central macular thickness was reduced to 369.0-324.0 and intraocular pressure was 17.0-3.0. Four of five eyes had increased intraocular pressure and were managed with intraocular pressure-lowering eye drops. Conclusion: We report improved functional and anatomical outcomes after treatment with fluocinolone acetonide intravitreal implant, indicating its use as a therapeutic alternative in recurrent cases of cystoid macular edema due to Irvine-Gass syndrome. Additionally, in eyes with suboptimal response to intravitreal therapies, fluocinolone acetonide intravitreal implant may provide longer recurrence-free periods with reduced treatment burden.
