What Is Tunnel Vision? Symptoms

Tunnel vision is a disorder where your field of vision narrows down to such an extent that it would be impossible to see what’s happening on either side of you. This is why it is called ‘tunnel vision syndrome’ or ‘peripheral vision loss, the lack of ability to view what’s happening towards the side of your visual field. An individual can either suffer from this disorder temporarily or may become a victim of it permanently.

This article explains tunnel vision syndrome and explains some of the significant symptoms and causes and the best action for treating it.

The Symptoms And Causes

One can lose their peripheral vision due to several reasons; some of the primary reasons include.

Cataract

This is an eye disorder that is due to the clumping of protein that makes up your eye. It can lead to the clouding of your lens and affects vision. There is also a particular kind of cataract that develops in the center of the lens. This condition is also known as a nuclear cataract. In numerous cases where individuals suffer from this condition, their lenses are damaged from the edge, which causes peripheral vision problems.

Some symptoms can include seeing two images of a single item, blurry vision, problem seeing objects at night, seeing colored objects as yellowing or faded, and extra sensitivity to light. Although different kinds of surgery solutions for cataracts are available, the best thing is probably to resort to natural ways that can help you prevent cataracts.

Glaucoma 

Glaucoma has been declared as the second-leading cause of blindness in the U.S. by the American Optometric Association. This condition is from a rise in pressure inside of the eye. However, there can be other causes behind the increase in pressure. It eventually damages the optic nerve in your eye and is also when individuals who suffer from this condition start to see blind spots appearing in their field of vision.

Retinal Detachment

As you might have guessed, the retina attached to the back of the eye is detached in this condition. The symptoms of this disease include floaters and flashes in the peripheral vision. This condition is a vision-threatening emergency. If you observe any symptoms or signs relating to retinal detachment, you should consult a medical professional immediately.

Retinitis Pigmentosa

This is a progressive eye disorder that targets and damages the cells sensitive to light in your retina, called ‘rods and cones, and is responsible for collecting visual information transmitted to the brain. The disorder often begins with peripheral vision loss. Regrettably, this condition’s pinpoint cause is yet to be known, although many associates it with genetic malfunctioning, and there is also currently no cure present for this condition.

Stroke And Concussion

Someone in the U.S. suffers from a stroke every 40 seconds, and every 4 minutes, someone dies from a stroke. According to a report in 2020 by The Centers for Disease Control and Prevention. Blood flow to the brain is disrupted due to stroke, leading to the brain’s deprivation of essential nutrients and oxygen. A stroke can cause confusing feelings, dizziness, as well as peripheral vision loss. Concussion also causes similar symptoms.

Ocular Migraines 

These are not the same as the migraine headaches either you or someone you know might experience. Ocular migraine remains painless for most people, but individuals suffering from this disorder experience a somewhat scintillating shimmer in their visual field; peripheral vision loss and halos may also appear around objects. Fortunately, the symptoms subside within a few minutes and are harmless.

Choroideremia

This is a rare genetic condition that primarily affects the male segment of the population. The victims of this genetic disorder continue to suffer from eye diseases over the years, leading to the complete loss of peripheral vision.

Alcohol-Induced Intoxication 

Consumption of alcohol in excess can similarly affect your vision, sometimes even damaging the peripheral vision to the level of tunnel vision syndrome.

Injury Induced Blood Loss

Under certain conditions, blood loss caused due to injuries can also cause tunnel vision.

Medication

Peripheral vision issues are not limited to hallucinogenic drugs and excessive alcohol. Still, they are also associated with the side effects of medicinal drugs such as brimonidine, scopolamine, nitroglycerin, along with several other medicines. Peripheral vision loss is also one of the most common side effects of the drugs mentioned above. Hence, you should consult with a medical professional first before taking any medicine.

Treating Tunnel Vision

Suffering from Tunnel vision is more than likely to affect you in various ways in your life; it takes away the convenience you once previously had and takes away the independence and ability to see things correctly.

Tunnel vision syndrome affects people; differently, it can be either temporary or permanent, regardless of the duration, it degrades the quality of life. Conditions such as a concussion or alcohol abuse can temporarily lose peripheral vision, whereas conditions like glaucoma can cause permanent loss of peripheral vision. Additionally, there are no viable treatments in incase you lose side sight due to retinal disintegration. Low vision aids are available, which can work along with appropriate visual rehabilitation can significantly help augment your receded vision.

Conclusion

Tunnel vision can be either permanent or temporary, depending on the cause. However, it will still negatively influence how you can live your life. This is also why Ophthalmologists recommend that you take good care of your eyes.
