Abstract:
The variability of the visual acuity in repeating testing using the whole-line method corresponds to three standardized optotype lines. A significant change of the visual acuity represents at least a doubling of the minimal angle of resolution. From the practical point of view the use of the interpolation method of Ferris is recommended. The mean variability of this method amounts only to 1.3 optotype lines and its realization is based on simple mathematical operations.
