(A) Bland-Altman plot reporting the near visual acuity (NVA) differences between the web-based test and the conventional ETDRS test. N = 85 eyes. The y-axis represents the differences between both measurements of one eye, the x-axis the mean of these measurements. Each circle represents one eye. 95% Limits of Agreement: -0.34 to 0.59 LogMAR, or -17 to 29.5 letters. (B) Distribution histogram summarizing the data shown in panel A. DVA: Distance visual acuity. LogMAR: logarithm of the minimum angle of resolution. 0.15 LogMAR = 7.5 letters
