Abstract
Aims
To assess time to, cumulative incidence of, and functional benefit of achieving sustained ≥2-step Diabetic Retinopathy Severity Scale (DRSS) improvement in diabetic macular oedema (DMO).
Methods
Post hoc analysis of VISTA/VIVID including eyes with DMO treated with intravitreal aflibercept injections (IAI), 2 mg q4 weeks (2q4, n = 250) or q8 weeks after 5 monthly doses (2q8, n = 249), or laser control (n = 249). Changes from baseline in best-corrected visual acuity (BCVA) and central subfield thickness (CST) were evaluated in sustained (≥2 consecutive visits) DRSS subgroups (≥1-step worsening, no change, ≥2-step improvement).
Results
Time to sustained ≥2-step DRSS improvement was shorter for both the IAI 2q4 and IAI 2q8 groups versus laser (both log-rank p < 0.001). Cumulative incidences of sustained ≥2-step DRSS improvement with IAI 2q4 and IAI 2q8 versus laser were 40.0% and 42.8% versus 15.5% (both p < 0.001) through week 100. Mean differences (95% CI) in BCVA gains from baseline at weeks 52 and 100 between eyes with sustained ≥2-step DRSS improvement versus sustained ≥1-step DRSS worsening were –3.0 (–8.9, 2.9) and 6.2 (0.2, 12.2) letters with laser, and 4.2 (0.8, 7.6) and 4.9 (1.3, 8.4) letters with IAI combined, respectively. Difference (95% CI) in CST reduction was significantly greater only with IAI combined at week 100 (–83.0 [–140.8, –25.3]). Correlations between BCVA and CST changes were weak.
Conclusions
DMO eyes treated with IAI achieved sustained ≥2-step DRSS improvement significantly earlier and more frequently versus laser. This improvement was associated with greater BCVA gains, independent of CST reductions.
