      The relation between elevated IOP and glaucomatous cupping is worryingly uncertain. Total population studies suggest an increasing incidence with increasing IOP, but the rise for each unit of IOP increase only becomes dramatic above 30 mm Hg.1Additionally, a significant proportion of patients with chronic glaucoma will have an IOP within the normal range.1 2 The susceptibility of an eye to a particular IOP level clearly varies, patient A being more susceptible to a particular IOP …
