Plasma cortisol suppression eight to nine hours after administration of 0.75 mg of dexamethasone was significantly greater in 85 patients with primary openangle glaucoma than in 77 normal subjects. The presence or absence of a visual field defect was not a meaningful factor. Plasma cortisol values after placebo administration increased significantly with age in glaucomatous patients but not in normals.
