Loss of Peripheral Vision

In this section, we will show you the reasons for peripheral vision loss.

A common cause of loss of peripheral vision is optic nerve damage from glaucoma. Eye strokes that block normal blood flow to the eyes internal structures, including the optic nerve, also can lead to loss of peripheral vision. In addition, a stroke or injury may also damage portions of the brain where images are processed, leading to blind sport in the visual field.

Of course, apart from the above reasons, peripheral vision loss can also be caused by the following reasons: glaucoma, retinitis pigmentosa, eye strokes or occlusions, detached retina, brain damage from stroke, neurological damage such as from optic neuritis, compressed optic nerve head, concussions, and so on.

So, if you have suffered peripheral vision loss, you can check the above reasons. However, you may ask how to treat the loss of peripheral vision.

Peripheral Vision Loss Can Indicate Several Issues

You may be used to managing your central vision with glasses and contact lenses, but your peripheral vision is very important too. Unfortunately, you may not notice if you begin losing peripheral vision until you have lost a significant amount of your ability to see movement, objects, or colors in that area.

Advanced peripheral vision loss leads to tunnel vision, which is defined as 90 degrees around your vision when you look straight ahead. The average, healthy eye has a range of 160 degrees around your central viewpoint. With tunnel vision, you may feel like you view the world through a narrow tunnel. Some severe forms of eye disease can limit vision so much that you have only 5 degrees around your central point of view.

There are several potential causes of peripheral vision loss. Some are acute and temporary, and others are chronic diseases. Sometimes, peripheral vision loss indicates a medical emergency.

Pearls And Other Issues

The first and most important management step in a patient with TVL is a thorough evaluation. Education of the public and the medical fraternity regarding a thorough evaluation of a patient with TVL will go a long way in reducing the risk of life-threatening vascular episodes like strokes, myocardial infarction, etc. Awareness should be increased that even though the symptoms are transient in nature but they may herald a serious underlying condition.

    What Conditions Cause Poor Peripheral Vision

    In most cases, peripheral vision loss is a side effect of an underlying health condition. The most common conditions that cause poor peripheral vision are glaucoma and retinitis pigmentosa.

    Glaucoma is a disease in which fluid builds up within the eye and creates pressure. Over time, this pressure can damage the optic nerve, which is the nerve that sends visual information from the eye to the brain. The more damaged the optic nerve becomes, the greater damage to peripheral vision. If left untreated, glaucoma can cause a complete loss of vision. Treating glaucoma early is the best way to protect eyesight.

    Retinitis pigmentosa is a genetic disorder that causes damage to the retina. The retina is the portion of the eye that is responsible for sensing light. As a result, those with retinitis pigmentosa may have difficulty seeing at night and differentiating between colors. The symptoms of retinitis pigmentosa generally begin in early adulthood and leaves most with this condition legally blind by the time they reach their 40s.

    Other conditions that can cause problems with peripheral vision include:

    • Optic nerve damage

    Diabetic Retinopathy And Peripheral Vision Loss

    Diabetes can harm the retinas tiny blood vessels, which supply it. Blood vessels can become leaky as a result of the injury, similar to a water hose with holes in it. Non-proliferative retinopathy is the name for this condition. Fluid escapes from blood vessels into the retinal tissue, potentially causing vision issues. The retina thickens, as a result, resulting in blurred vision.

    Blood arteries injured by hyperglycemia close in another process, triggering a chain of events. When retinal tissue is starved for oxygen it grows, resulting in the formation of new blood vessels on the retinas surface. This is called neovascularization. Proliferative retinopathy is a condition in which new blood vessels grow in the retina.

    These newly formed blood vessels are fragile and prone to rupturing and bleeding. This causes scar tissue to form on the back wall of the eye, stretching the retina and finally detaching it from the back wall. Retinal detachment is the medical term for this disorder, which can occur suddenly or gradually over time.

    In cases that involve glaucoma, it is vital that a person takes their glaucoma medication to control high eye pressure. Without it, the risk of permanent optic nerve damage and blind spots is very high. Left untreated glaucoma can lead to blindness.

    There is also treatment available for blind spots that develop as a result of brain damage. Researchers in New York recently discovered a therapy to help people regain some visual field loss linked to the brains primary visual cortex. Interestingly, there are techniques taught by sports vision specialists that can train the eye to have a better field of view as well.

    Those who have permanent peripheral vision loss should see a low vision specialist who can provide guidance on optical devices to help with mobility issues caused by the vision loss.

    Peripheral Vision Loss Signs And Symptoms

    The primary symptom of peripheral vision loss is tunnel vision. When this symptom occurs, you are only able to see a small circle straight ahead. You may also have difficulty seeing in low light and have trouble walking.

    Peripheral vision loss does not always occur rapidly. As a result, many sufferers do not immediately realize they are experiencing a loss of peripheral vision, and do not receive diagnosis until examined by an eye care professional.

    Treatments For Peripheral Vision Loss

    Glaucoma

    Unfortunately, there are no easy vision correction options such as conventional eyeglasses or contact lenses that can correct permanent loss of peripheral vision. A type of lens known as a prism sometimes can be added to your eyeglasses prescription to expand your field of view if you have certain types of peripheral vision loss.

    If you have glaucoma, the best “cure” for tunnel vision is prevention. If eye drops are prescribed, you absolutely must take your glaucoma medication regularly to control high eye pressure, or you risk permanent optic nerve damage and development of blind spots in your visual field. Left untreated, glaucoma can lead to permanent loss of peripheral vision and even blindness.

    Therapy also may be available for blind spots created by brain damage. University of Rochester Eye Institute researchers in New York recently discovered that specific vision therapy techniques may help people regain at least some visual field loss linked to damage in the brain’s primary visual cortex.

    Even if you have normal vision, you might use some techniques such as those taught by sports vision specialists to train yourself to see better in the peripheral parts of your field of view. These methods can be helpful particularly if you need to hone your peripheral vision skills for sports such as football and cricket.

    Peripheral Vision Is Important

    Stare straight ahead of you. Now, without moving your head or eyes, be aware of the things existing in your field of vision to the left and right. Being able to see things outside of your direct field of vision is peripheral vision. While central field of vision is obviously the most important, research has found that peripheral vision is essential as well – and for surprising reasons. Studies found that peripheral vision was the sense most closely associated with giving your brain the information it needs to break down what type of scene you’re looking at. For example, peripheral vision is important in helping your brain determine whether you’re looking at a beach, a mountain, traffic, or a field.

    Diagnosis Of Peripheral Vision Loss

    There are obviously many causes of peripheral vision loss problems. Regular visits to your eye doctor are important to prevent peripheral vision loss. Diagnosing eye conditions in the early stages is key to maintaining good peripheral sight. Dilated eye exams, visual field tests, and cardiovascular tests all help to determine the underlying causes of peripheral vision loss.

    Many conditions that cause vision can be diagnosed with a visit to your primary care doctor. A healthy diet and lifestyles are so important for not only your body but your eye health also.
