Fluocinolone acetonide (0.19 mg) intravitreal implant reduces treatment burden and improves practice resource utilisation for patients with diabetic macular oedema

Abstract

ObjectivePatients with diabetic macular oedema (DME) are known to have significantly greater medical treatment burden than patients with non-DME. Frequent injections and office visits can have a substantial impact on patient adherence and quality of life. This analysis assesses the impact of the 0.19 mg fluocinolone acetonide (FAc) implant (or injection) on treatment burden and practice resource utilisation in patients with DME.Methods and analysisThis study is a single-centre retrospective chart review of 30 eyes (23 patients) that received a single FAc implant. Data was collected for a 12-month period pre-injection and post-injection of the FAc implant. Primary outcomes included the frequency of injections and ophthalmology office visits. Secondary outcomes included visual acuity (VA), intraocular pressure (IOP) and central subfield thickness (CSFT).ResultsThe injection frequency significantly decreased from one injection every 2.6 months pre-injection to one injection every 8.8 months post-injection of the FAc implant (p<0.001). Sixty-three percent of the subjects did not require additional injections post-FAc implant. The mean number of ophthalmology office visits significantly decreased from 12.7 visits pre-FAc to 9.3 visits post-FAc implant (p<0.001). The mean VA (p=0.24) and CSFT (p=0.39) showed a mild numerical improvement that was not statistically significant. Thirty-seven percent of the eyes required additional IOP lowering drops. No eyes required incisional glaucoma surgeries.ConclusionsThe FAc implant significantly decreased the treatment burden and improved practice resource utilisation while maintaining or improving VA and CSFT. IOP events were mostly well-controlled with drops and no eyes required incisional glaucoma surgery.
