What Causes Peripheral Vision Loss?
This loss of vision in the peripheral visual field (peripheral field deficit) can be linked to optic nerve damage caused by glaucoma, high internal eye pressure and other conditions. Eye “strokes” (occlusions) that block normal blood flow to the eye’s internal structures, including the optic nerve, can lead to sometimes permanent eye damage and loss of peripheral or central vision. A stroke or injury also may damage portions of the brain where images are processed, leading to blind spots in the visual field. Basic causes of peripheral vision loss include: • Glaucoma • Eye strokes or occlusions • Detached retina • Brain damage from stroke, disease or injury • Neurological damage such as from optic neuritis • Compressed optic nerve head (papilledema) • Concussions (head injuries)* If you suspect you have lost peripheral vision, you may need to undergo visual field testing to identify where blind spots (scotomas) have occurred, to help your eye doctor with a diagnosis.
