What is tunnel vision?

If you suffer from tunnel vision, also known as tubular vision, your visual field is restricted. Your peripheral vision will be impaired, limiting your visual field to a tunnel that becomes smaller and smaller. As a result, you will only be able to see part of your surroundings and will have to turn your head and move your eyes to see everything around you.

What Causes Tunnel Vision?

Tubular vision can be caused by Retinitis Pigmentosa and Glaucoma, two eye conditions. The eye contain light-sensitive cells, which are also known as rods and cones. The rods are located in the outer part of the retina, while the cones are situated in the middle. With tunnel vision, the rods in the eye die off, causing your peripheral vision to deteriorate. Initial symptoms may include seeing black or blurry spots. As the rods continue to die off, the black spots will become larger and your visual field will get smaller. Ultimately, only a small part of your visual field will be left, making it feel as if you are looking through a tunnel. The cones are responsible for central vision and let us see sharply, for instance.

Tunnel vision treatment

Whether or not tunnel vision can be treated depends on what caused it. If it is caused by Glaucoma, an eye condition, medication, laser treatment or surgical treatment is possible in an attempt to limit damage to the optic nerve by reducing eye pressure. The most common cause, however, is Retinitis Pigmentosa, for which no treatment is currently known. Support, however, is always necessary, as loss of vision also has a significant impact on personal safety. Due to your diminished visual field, you might not see things coming or walk into things, for example. We offer support to help keep patients function in society for as long as possible.

Diet and nutritional supplements to combat Tunnel vision

The same applies as to all other eye conditions: ‘a healthy lifestyle is very important’.
The best steps you can take are refraining from smoking, consuming little to now alcohol, and eating nutritious meals. Our eyes need nutrients to stay healthy, most importantly: Antioxidants, Alpha-lipoic acid, Omega 3 fatty acids, Vitamin A, C and zinc. Lutein and Zeaxanthin are also very important, but seeing as our bodies are incapable of producing these pigments, we have to depend on food or supplements. Food that contains these nutrients is very good for your eyes, but you can also take nutritional supplements in addition to your daily diet. Always make sure to consult with your doctor before you start taking supplements with your medication.
