Loss of Peripheral Vision

Loss of peripheral vision, commonly known as “tunnel vision,” occurs when the centre of the visual field functions but peripheral vision is absent. Glaucoma and retinitis pigmentosa are common causes of this type of blindness. People with limited peripheral vision may need to stand directly in front of something or turn their head in order to see it. They can experience difficulty navigating through the built environment.
