Statistical significance of various characteristics of patients with glaucoma, related to their likelihood of their developing visual field loss as observed in the Advanced Glaucoma Intervention Study (AGIS). The slope of the visual field (VF) refers to the rapidity with which the visual field is worsening in units of visual field loss/years. “AGIS VFS” indicates the amount of visual field loss according to the AGIS system of staging visual fields. IOP mean indicates the mean intraocular pressure in mmHg. IOP fluctuation refers to the fluctuation of intraocular pressure. Eye (right) refers to comparison of the IOP in the right eye versus the left eye. (Histogram created on the basis of data from citation 8.)
