To report functional and morphologic outcomes, based on diabetic macular edema (DME) chronicity and baseline best-corrected visual acuity (BCVA), from a subanalysis of the fluocinolone acetonide for macular edema (FAME) trials.Patients were categorized by DME duration (nonchronic [ncDME] or chronic [cDME] DME) and three nonexclusive baseline vision strata. Anatomic and visual acuity VA outcomes of these cohorts were compared with treatment assignment.For all patients with ncDME and cDME who received sham control, 27.8% and 13.4%, respectively, gained ≥15 BCVA letters, whereas 22.3% and 34.0% of 0.2 μg/day fluocinolone acetonide (FAc)-treated patients, respectively, gained ≥15 BCVA letters. Among patients with ncDME who received sham control, as baseline vision decreased, the percentage gaining ≥15 BCVA letters increased; however, among those with cDME, the percentage gaining ≥15 BCVA letters did not change as baseline vision decreased. Conversely, among 0.2 μg/day FAc-treated patients, the percentage gaining ≥15 BCVA letters increased with decreasing baseline vision, regardless of DME chronicity. Anatomical outcomes were similar within treatment arms, regardless of the DME duration.Patients with cDME and poor baseline vision who were exposed to low-dose FAc experienced BCVA improvements that were not observed in a similar group from the sham-control arm. These data support the multifactorial pathogenesis of cDME.
