The Kaplan–Meier method was used to compare visual prognostic survival according to they cumulative duration of the presence of subretinal fluid (< 6 months or > 6 months). The red line indicates the < 6 months group, whereas the blue line indicates the > 6 months group. (a) Percentage of patients with visual acuity loss of ≥ 0 logMAR (p < 0.0001). (b) Percentage of patients with visual acuity loss of ≥ 0.1 logMAR (p < 0.0001). (c) Percentage of patients whose visual acuity decreases by ≥ 0.2 logMAR (p = 0.0041). (d) Visual acuity change of ≥ 0.3 logMAR (p < 0.0001). For both visual acuity criteria, a significant difference was observed between the cumulative duration of the presence of subretinal fluid at < 6 and > 6 months. logMAR logarithm of the minimum visual angle.
