    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

    Optic Neuritis: An Inflamed Optic Nerve

    Your optic nerve works like a sight highway. Signals move from the eye to the brain down this path, and it’s that movement that helps you to see clearly. Swelling in the optic nerve can slow or even block those messages.

    Optic neuritis is closely related to multiple sclerosis . This condition causes nerves all around the body to swell, and researchers say about a third of people with MS do not know they have the condition until they develop optic neuritis.

    It’s also been associated with risks such as:

    • Infections. Lyme disease, syphilis, cat-scratch fever, and bacterial invasions can all cause the optic nerve to swell.
    • Viruses. Herpes, mumps, and measles can cause optic neuritis.
    • Medications. Some types of antibiotics and the drug quinine can cause swelling in the optic nerve.

    Optic neuritis usually attacks one eye while leaving the other intact, says Mayo Clinic. You might notice:

    • Vision loss. Some people develop a slight blurring or dimming of vision, while other people can’t see anything at all. Some people retain clear central vision, but can’t see anything to the side.
    • Visual hallucinations. You may see flashing or flickering lights. Colors might seem dim or dull.
    • Eye pain. You might develop a headache, and it can get worse when you move your eyes.

    Loss Of Peripheral Vision: Risks And Complications

    Living without peripheral vision is not only very annoying, but can be a safety hazard. Without good peripheral vision, it is harder to notice dangers that could be right in front of you. Driving a car is out of the question when you have tunnel vision, as the risk of injury to yourself or others is just too high. The same goes for riding a bicycle.

    If you have lost peripheral vision, it is safest to have a friend or family member come with you when you are out doing errands. A companion can serve as a second pair of eyes so you are safe when walking. Also, it may be disheartening but necessary to suspend some of your hobbies while your vision problem is being addressed.

    It is unfortunate, but there are situations where peripheral vision loss is caused by vision-threatening or life-threating conditions, such as cancer.

    Even in situations where symptoms seem mild, getting professional care is important so that you can avoid complications. Those complications could include permanent loss of vision or blindness, brain damage, or unconsciousness.

    Preventing Loss Of Peripheral Vision

    Peripheral Visual Fields

    There are no easy prevention tips for loss of peripheral vision, but you can control some of the conditions that may put you at a higher risk for vision loss. For instance, getting a complete eye exam every two to four years, beginning at the age of 40, will allow your eye specialist to catch any abnormalities early so that they dont progress to the point where you are permanently visually impaired.

    Those who enjoy sports and other physical activities can protect their eyes by wearing glasses or goggles. A lot of people dont realize it, but eye injuries can lead to glaucoma.

    It is also worth noting that many studies have shown that regular exercise can help your eye health. As it turns out, being physically active can reduce eye pressure, which is the main cause of glaucoma. Exercise can also lower high blood pressureanother risk factor for vision problems.

    We can all agree that our eyes are precious, yet a lot of people take them for granted. Getting regular check-ups and protecting the eyes is important. It is equally important to pay attention to the signs of peripheral vision loss and see a health care professional if you notice symptoms.
