The visual field of low tension glaucoma and shock-induced optic neuropathy
S. M. Drance
The visual fields of patients with shock-induced optic neuropathy with
excavation, low tension glaucoma, and chronic simple glaucoma were
analyzed. True altitudinal defects are seldom found. The three disease
states showed identical field defects. Subtle defects can occur in all
three disease states. The preponderance of defects occurred in the upper
field. There are obvious differences from ischemic optic neuropathy.
