What causes loss of the visual field?
Glaucoma, vascular disease, tumors, retinal illness, genetic disease, optic neuritis and other inflammatory processes, nutritional deficiencies, toxins, and medicines are just a few of the many conditions that can result in visual field abnormalities. Some visual field loss patterns can be used to identify a potential underlying cause.
What's the visual field normally?
An island of vision that is 90 degrees temporally to the center of fixation, 50 degrees superiorly and nasally, and 60 degrees inferiorly makes up a normal visual field. Moving from movement discrimination in the extreme periphery to better than 20/20 in the center of vision, visual acuity improves.
