The pattern electroretinogram was recorded in patients with initial stages of visual field defects due to open-angle glaucoma and in age-matched normal subjects. Both normal subjects and glaucoma patients had a visual acuity above 0.8. Counterphasing checkerboard patterns were used as visual stimuli

β¦ Synopsis
Fourteen patients with advanced open-angle glaucoma were evaluated prospectively by electroretinography and the results were compared with normal controls who were matched for age and sex. All glaucoma patients had visual acuity of 20/50 or better, cup4o-disc ratios of 0.7 or greater in at least one eye, and visual field loss consistent with advanced glaucoma. Numerous eleetroretinographic parameters were significantly abnormal when compared with the control group.

Systemic autonomic nerve function was assessed in 67 patients with open-angle glaucoma and 76 age-and sex-matched control subjects, using a series of well-established tests based upon cardiovascular reflex responses to standardised stimuli. Parasympathetic neuropathy was present in 37.3% of open-ang
## Purpose: To investigate possible associations between genetic markers and primary open-angle glaucoma (poag). ## Methods: A number of genetic markers were typed in 84 unrelated patients with poag and compared with a random sample of healthy individuals. the markers were transferrin, group spec
