The Visual Field of Low Tension Glaucoma and Shock-Induced Optic Neuropathy

Abstract

• 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. (Arch Ophthalmol 95:1359-1361, 1977)
