Peripheral vision refers to the outer edges of a person's encompassed field of vision, in effect allowing one to see things and movement outside of one's direct line of vision. Peripheral vision is that part of our vision working during activities like driving, walking, and dodging—all the time. One's view of the world becomes greatly limited with the loss of peripheral vision; simple tasks become challenging and sometimes dangerous.
Causes of Peripheral Vision Loss
There are several concomitants to peripheral vision loss. Some of the common ones include:
- Glaucoma
This is an eye disease that causes damage to the optic nerve and mostly causes the loss of peripheral vision. Glaucoma mostly relates to increased pressure inside the eye, which may gradually damage from the hardening of the optic nerve fibers carrying peripheral vision.
- Retinitis Pigmentosa
A hereditary degenerative disease of the retina that might result in progressive blindness. The symptom appears during early childhood or teenage years and will take many years to progressively cause loss of peripheral vision.
- Stroke
Stroke to the ventral pathways of the brain from the occipital cortex may result in defective peripheral vision. This could be permanent and, depending on the magnitude and location of the stroke, it might remain transient.
- Brain Injuries
There is some amount of violence to the head that can result in damage to the brain, especially areas responsible for your ability to see. These are usually caused by accidents, falling, and sometimes even sports injuries, which may involve one or both sides of your field of vision.
- Retinal Detachment
A condition where the retina peels off from the layer of the supporting tissue. If not checked on time, it brings about severe and permanent loss of vision.
Symptoms of Peripheral Vision Loss
The first treatment for possible peripheral vision loss is to be able to first identify its symptoms. Symptoms of peripheral vision loss include:
- Problems with low-light viewing
Difficulty viewing in dark places tends to be one of its common symptoms. It can pose another danger with activities like driving at night or even walking in poorly lit places.
- Frequent Tripping or Bumping
Due to this eye disease, people with narrowed peripheral vision are likely to engage in accidents because they do not notice the obstruction that leads to it. A loss in peripheral vision will often see a person bumping into furniture and items that fall outside a narrowed field of vision.
- Tunnel vision
Constriction of the peripheral field of vision is only clear in the center. This could result in a sensation of tunnel vision wherein things are seen to be viewed down some tube or are only in focus at the center and, on the sides, blurry or out of focus.

Diagnosing Peripheral Vision Loss
Peripheral vision loss has to be diagnosed early to handle the situation. An eye-care professional has many tests which will first assess the degree of your vision loss and then pin-point its cause:
- Visual Field Test
You are supposed to identify the area of your peripheral vision. You would have to face straight ahead while lights or other objects move just in front of you in various visual fields.
- Optical Coherence Tomography
It is the scanning of the retina for any abnormality. OCTs produce images of the layers of the retina, and hence they easily detect problems like glaucoma or retinal detachment.
- Electroretinography
It is the electrical response resulting from the light stimulation of the retina. This test will confirm whether the problem relates to diseases of the retina, for instance, retinitis pigmentosa.
Treatment for Loss of Side Vision
Treatment depends on the cause of the problem. Common options include:
- Medications
As a way to treat glaucoma, the doctor may prescribe medication to try and reduce the pressure within the eye. By giving prescriptions trying to slow the progressive development of the ailment and maybe retaining an amount of vision that has remained, a doctor would recommend using eye drops or oral medication.
- Vision Therapy
The visual skills may be improved with training and various exercises, which may further add to the compensation of the vision loss. Exercises may involve those that will enhance the coordination of the eyes, focusing abilities, and peripheral awareness.
- Laser Therapy
This is more common in diseases like diabetic retinopathy or glaucoma, which can help seal leaking blood vessels, reduce intraocular pressure, or prevent further damage to the retina.
- Lifestyle Changes
To some extent, the onset of the effect due to loss of peripheral vision can be delayed by keeping diabetes and blood pressure, etc. in control. The nutrition should be healthy with a fair amount of exercise and without smoking.
Living with Peripheral Vision Loss
Along with peripheral vision loss, you have to make some lifestyle adjustments and hopefully support it with the use of adaptive instruments. Some tips are presented herewith for the same:
Home modifications
Set up furniture to prevent bumping into things, and improve lighting to decrease falls. Remove rug ways from your place and take away the tripping hazards to make a safer living space. Improve the lighting to reduce falls.
Mobility training
Learn some walk-around techniques with the help of someone, safely. Consider also the orientation and mobility training to move around confidently and safely with the help of a specialist in this area.
Support Groups
These can provide emotional and general tips on how to cope. Having others who have gone through similar incidents can be very supportive.
Preventing Peripheral Vision Loss
While one's good health cannot prevent all occurrences of peripheral vision loss, it may help to reduce risks. Ways in which include:
Routine Eye Exams
Eye problems can be prevented, or at least slowed down to a point if detected early. This regular checkup can, therefore, guarantee the timely identification and treatment of problems with their vision.
Healthy Living
The right diet and regular exercise besides not smoking will cut the chances of getting chronic diseases like diabetes and hypertension, which might in turn cause blindness.
Proper Protection to the Eyes
Wear dark glasses to protect your eyes from ultraviolet rays. Safety glasses help protect your eyes from damage. Keep your eyes safe in case you are involved in something that may hurt your eyes.
Conclusion
It means that it's an exacting situation to be losing peripheral vision; however, knowing the causes, symptoms, and treatments can help in its management. Peripheral vision eye checks alone cannot substitute for a healthy lifestyle, which is important for good health in vision. Consultation with an eye care professional in case of peripheral vision change is very necessary. Early intervention turns out to make a difference in saving vision and improving the quality of life.
