Tunnel Vision

Tunnel vision is the loss of your peripheral vision. There are lots of different causes, some more serious than others. Book an appointment straight away so we can help you get the help you may need. Choose from our range of eye care packages.

Tunnel vision can be temporary and tends to be a result of emotional stresses, such as panic, or anger. Alcohol and drugs can also affect your vision in this way and normally your vision returns once you are no longer in a heightened state.

Damage to your retina

Retinitis pigmentosa is a group of eye diseases that affect the retina. The condition causes the photoreceptors cells to deteriorate resulting in a loss of peripheral vision initially. This normally happens from the age of 10 years or during adolescence. The rods (one of the two types of photoreceptors that captures the images we see) are normally the first to be affected by the condition; they capture the light and are located on the periphery of the retina. You may therefore begin by having difficulty seeing at night, and as the condition worsens your peripheral vision is deteriorates, giving you the impression you are looking through a tunnel.

A family and medical history will help us assess your risks and ophthalmoscopy (when we look into the back of your eye), will enable us to screen for the condition’s presence within your retina.

Should pigmentosa retinitis be suspected, we will refer you to an ophthalmologist who will undertake further examinations including genetic screening and electroretinogram (ERG). During this test, different-coloured lights are flashed into the eyes as you look at a large reflective globe. Should the diagnosis be confirmed you will have access to a team of people and resources to help you.

Should you be on one of our eye care packages we will undertake a series of tests to establish a detailed work- up for the consultant, which will contribute to the establishment of a comprehensive baseline from which to monitor your vision. This will help in managing the symptoms such as the introduction of tints to enhance contrast. Should you have been on our package for some time, historical data will be useful to advise your ophthalmologist of how your vision has changed over time.

Damage to the optic nerve

The optic nerve carries the information from the eyes to the brain. Injury or disease to the optic nerve can cause tunnel vision. Glaucoma is a fairly common disease, particularly in those over 40 years. It is slow-moving and affects the peripheral vision. It is caused by an increase in pressure within the eye that restricts and damages the optic nerve.

Examination of your optic discs and visual field, along with your pressure, will enable an initial conclusion to be made within our standard eye examination and so offer a referral for further tests under the NHS.

Should you choose one of our packages, further tests will be undertaken to determine the extent and nature of a potential condition using Gonioscopy, advanced visual fields and OCT of the cornea, as well as Volk lens examination on the slit lamp. This detailed report will enable a referral (should it be necessary), to be considered a verified referral.

Systemic cause

Migraine

Migraine is a type of headache that can result in peripheral vision loss that is temporary.
