Abstract
PURPOSE: To evaluate the management and long-term outcomes of patients with diabetic macular oedema (DMO) and good initial visual acuity in real-world settings. METHODS: We reviewed 122 eyes of 100 patients with treatment-naive DMO and initial best-corrected visual acuity (BCVA) of 20/25 or better. We assessed clinical characteristics, logMAR BCVA, central subfield thickness (CST), cumulative intravitreal injections and laser treatments at yearly intervals, and characteristics at time of initial treatment. Linear mixed effects models were used to identify predictors of visual outcomes. RESULTS: At presentation, mean BCVA was 0.057 ± 0.048 logMAR (Snellen 20/23) and mean CST was 288 ± 57 μm. After a median follow-up of 3 years, 51% of eyes underwent treatment. More eyes underwent intravitreal injection as initial treatment (54%), but lasers were initiated at an earlier time and at better BCVA. Final BCVA was associated with better BCVA (P < 0.001) and earlier timing (P = 0.017) at initial treatment, but not CST at first treatment (P = 0.634) or cumulative number of injections or lasers (P = 0.441-0.606). CONCLUSION: DMO with good initial visual acuity should be monitored closely, as delay in treatment initiation is associated with worse visual outcomes. BCVA at time of initial treatment is the strongest determinant of final visual acuity.
