Probability of becoming visually impaired before dying for the situation in which an individual rate of progression is known (patients with at least 5 years of perimetric follow-up), for men (a) and women (b). Patients with an age and current mean deviation combination that brings them above their individual rate of progression line have a probability of <5% of becoming visually impaired before dying; below this line, this probability is >5%. Visually impaired was defined as a mean deviation of −20 dB.
