Table 4. Best-corrected visual acuity of the treated eye and composite Visual Function Questionnaire scores throughout the study period.
| Baseline (197 patients, 214 eyes) | 3 Months Follow-up (187 patients, 202 eyes) | 12 Months Follow-up (n = 171 patients, 186 eyes) | |
| BCVA of the treated eye, median (IQR), ETDRS letters | 59 (48–70) | 62 (48–72) | 62 (47–72) |
| Composite VFQ Scores, median (IQR)a | 84 (67–91) | 85 (68–92)b | 83 (65–90)c |
Abbreviations used: BCVA = best-corrected visual acuity, IQR = interquartile range, ETDRS = Early Treatment Diabetic Retinopathy Study, VFQ = Visual Function Questionnaire.
a
Significant change throughout the study period, p<0.001 in Friedman's two-way analysis of variance by ranks.
b
Significant change between baseline and 3 months follow-up, p = 0.004 in Wilcoxon signed rank test.
c
Significant change between 3 and 12 months follow-up, p<0.001 in Wilcoxon signed rank test.
