In the cases reported here, in which there were cupping of the atrophic optic disk and low ocular tension, the changes in the visual fields were not common to glaucoma and remained stationary in their course for a long time. To study this phase, in which they also differ from the course in cases of the usual type of glaucoma, I endeavored to follow up the cases which were reported in an article on "Association of Sclerosis of the Cerebral Basal Vessels with Optic Atrophy and Cupping," presented before the American Ophthalmological Society in 1932, and I am now ready to report on the subsequent histories of those which are available and of several which have been added since that date, making 11 cases in all.
In this series a group of cases can be distinguished in which the changes in the visual field are altitudinal. The condition in such
