Nearly half of patients with glaucoma-related mild central visual loss had defects in the far peripheral inferotemporal visual field, often in the form of temporal wedge or sector defects correlated with damage to the superior nasal optic disc nerve fiber bundles.

“We believe finding visual loss in the far peripheral field with OCT correlation could affect treatment decisions for glaucoma patients,” Michael Wall, MD, from the departments of ophthalmology and neurology at University of Iowa, College of Medicine, Iowa, and colleagues wrote in their study.
