Early visual field disturbances in glaucoma
E. B. Werner and S. M. Drance
Twenty-two eyes of 22 patients with initially normaly visual fields
developed glaucomatous field defects. In 13 of these, the development of
the definitive field defect was preceded by a localized minor disturbance
in the area where the defect appeared subsequently. In a control group of
22 ocular hypertensives without field defects, six eyes had localized
disturbances similar to those that preceded the field defects in the study
group. This type of minor localized disturbance may represent an early
glaucomatous visual change detectable before the appearance of definitive
scotomas.
