# Tunnel vision (peripheral vision loss)

Tunnel vision describes constriction of the visual field so that only central vision remains relatively intact. People feel as if looking through a narrow tube.

## Causes

Both ocular and neurological disorders can produce peripheral field loss.

- Advanced glaucoma and retinitis pigmentosa as common ocular causes
- Neurological conditions affecting visual pathways, such as stroke or pituitary tumours
- Functional or non-organic visual loss in some cases
- Formal visual field testing helps define extent and pattern

## Living with tunnel vision

Adaptations can improve safety and independence.

- Orientation and mobility training to scan effectively and avoid obstacles
- Prism or reverse telescopic lenses in selected patients
- Driving restrictions depending on legal field requirements
- Support from low-vision services and rehabilitation specialists
