Figure 1
A schematic illustrating the VF series inclusion criteria and method for calculating rates of MD loss (dB/year) for three example eyes detected in 2001 (a), 2003 (b), and 2006 (c). Eyes were excluded for o5 VF examinations or o4 years of follow-up. The first VF in each series was omitted to account for perimetric learning effects. Rate was calculated from linear regression of the baseline VF and the series of exams that fell within a 4-year period after it (white window). So, for example, for series (a) the sixth and seventh recorded VFs fall outside this window and are not used in the calculation. This ensures that all rates are estimated with equivalent precision, allowing for comparisons over time. A minimum of three VFs were required to be in this 4-year window. This rate was then assigned to the date of the baseline exam.
