8 Causes of Peripheral Vision Loss

Peripheral vision loss is the loss of side vision. Peripheral vision helps you see the surrounding objects without turning your head or moving your eyes. It also helps you sense motion and lets you carry various activities such as running, walking, and driving without crashing into anything. To understand more about peripheral vision, let us first give you a brief insight on the retina. 

8 Causes of Peripheral Vision Loss

2 types of cells in the retina 

There are 2 types of light-sensitive cells in the retina: rods and cones. The cones help us see colour and are concentrated in a small central area of the retina called the macula. Rods are responsible for peripheral and night vision. Loss of peripheral vision or tunnel vision typically results from eye conditions that inhibit the normal functioning of the rods. 

Symptoms of peripheral vision loss – when to see an eye specialist? 

When people suffer from moderate to severe peripheral vision loss, they feel as if they are looking down a narrow tube. Some of the other symptoms of peripheral vision loss include: 

  1. Poor night vision
  2. Blind spots
  3. Eye pain
  4. Headaches 
  5. Nausea
  6. Increased or decreased light sensitivity
  7. Change in the size of the pupils 
  8. Seeing glare around lights

If you are noticing any of these symptoms, book an appointment with an eye doctor in Kolkata

What causes peripheral vision loss?

Loss of peripheral vision may be the result of:

  1. Glaucoma: It is one of the most common causes of peripheral vision loss. Glaucoma causes elevated intraocular pressure (IOP). Extremely high IOP results in optic nerve damage, which leads to a loss of side vision. People suffering from diabetes are at an increased risk of suffering from Glaucoma. Hence, it is important for Diabetics to visit their eye doctors regularly. If you are a diabetic and searching for the best eye doctor in Kolkata,  check our list of eye doctors – they are some of the best names in Kolkata. From reputed eye surgeons to the best retina specialist doctors in Kolkata, we have some of the leading names in our team. 
  2. Eye Stroke or Retinal Artery Occlusion: Eye strokes are caused by clots or narrowing of your retina’s blood vessels. When the blood flow to the retina is interrupted, it can result in various vision problems, including peripheral vision loss and even total vision loss. 
  3. Retinitis pigmentosa: It refers to a group of rare eye conditions caused by genetic mutations. These conditions are inherited genetically and affect the retina, resulting in night blindness, tunnel vision, and other vision problems.
  4. Cataracts:  It is a buildup of proteins in the lens, forming protein clumps. In many cases, cataract starts damaging the lens from the edges leading to peripheral vision loss. 
  5. Optic Nerve Atrophy: When the optic nerve is damaged it can affect your central vision, peripheral vision, and color vision. 
  6. Retinal Detachment: It is a painless yet serious condition that occurs when the retina separates from the back of your eye. It can be caused by tears or holes in the retina, an inflammatory disorder, Coats’ disease, or the contraction of scar tissue on the retina’s surface. Over time a detached retina can cause loss of peripheral vision. 
  7. Ocular Migraine: They happen when the blood flow to the eye is restricted. Someone who is suffering from ocular migraines can experience peripheral vision loss and other visual disturbances for a short period of time. 
  8. Papilledema: Swelling of the optic disc, called papilledema, can lead to vision problems including loss of side vision. 

How to test peripheral vision? 

Your eye doctor will perform a visual field test to check how much you can see out of the corners of your eyes. This is a simple, painless, and non-invasive procedure.

13 Eye Health Related FAQs

Have doubts about eye health? Check out the FAQs below:

1) How do cataracts develop and what are the treatment options?

There are two risk factors for the development of cataracts; age and exposure to ultraviolet rays.

Age-related cataracts occur when proteins in the eyes form clumps and restrict the amount of light that enters the retina. Prolonged exposure to ultraviolet rays is another cause of cataracts. Other causes of cataracts include eye diseases and eye injuries.

Cataracts can be treated with an eye surgery in which the surgeon replaces the cloudy lens with a clear, artificial lens. But the surgery should be done from the best eye hospital in West Bengal.

2) How is cataract diagnosed?

Cataract can be diagnosed through a comprehensive eye exam, including dilated eye exam and visual acuity test.

In a dilated eye exam, the doctor dilates the pupils using eye drops. By doing this, the doctor can determine cataracts’ opacity and impact on vision. The doctor is able to determine the extent of vision impairment through the visual acuity test.

3) Can I get a cataract surgery done during summers?

Yes. You can undergo a cataract surgery during summers. In fact, you can undergo a cataract surgery during any time of the year. Cataract surgery not being feasible during summers is just a myth.

4) What is diabetic retinopathy and what are its symptoms?

Diabetic retinopathy is a complication of diabetes; the eye condition is one of the leading causes of blindness. It occurs when high blood sugar levels damage the tiny blood vessels in the retina.

The early symptoms of diabetic retinopathy go almost undetected, but can gradually worsen over time, leading to vision loss. Some of the common symptoms of diabetic retinopathy include eye pain, double vision, eye floaters and spots, and blurred vision.

5) Who are at the risk of diabetic retinopathy?

People suffering from diabetes, both Type 1 and Type 2, stand at the risk of diabetic retinopathy. Pregnant women with diabetes are at the equal risk. Disha Eye Care Hospital is the best among the top ten hospitals for retina treatment in Kolkata.

6) Can diabetic retinopathy be prevented? If yes, how?

There are several steps to lowering the risk of diabetic retinopathy. Managing diabetes is the first step to minimising the risk of onset of the eye condition. Other steps involve regularly checking blood sugar levels, testing urine for ketone levels, and undergoing an annual comprehensive eye exam.

7) Can eye injuries affect vision?

Yes, but it totally depends upon the severity of the eye injuries. Minor injuries can cause eye pain and temporary blurred vision while major injuries can have serious implications such as eye infection and vision impairment.

8) How to protect the eyes from diseases?

There are several ways how you can lower the risk of development of eye diseases. First off, maintain a healthy diet by choosing fresh vegetables, fruits, eggs, meat, and fish over unhealthy food items such as deep-fried snacks and frozen meat items.

Exercise regularly, drink plenty of water, and get your eyes checked every year. These steps help you maintain an overall good health and keep the risks of eye diseases at bay.

9) What is glaucoma and what are its symptoms?

Glaucoma is a group of diseases that can cause vision loss by damaging the eyes’ optic nerve. The eye disease is linked to the build-up of pressure (intraocular pressure) inside the eyes

Some of the common symptoms of glaucoma include eye pain, narrowed vision, nausea, vomiting, eye redness, vision loss, and seeing halos around the light.

10) What are the treatment options for glaucoma?

Your doctor may plan the treatment depending upon the severity of the condition. Eye drops for Glaucoma can either increase fluid flow or reduce its formation in the eyes.

Laser surgery is another treatment option for glaucoma. This procedure can help increase fluid flow in the eye. A surgery known as Trabeculoplasty involves opening a new channel to drain the fluid and lower eye pressure.

11) Why is it not safe to wear contact lenses past expiry/recommended date?

Contact lenses (as the name suggest) get into direct contact with the eyes when worn. Therefore, it’s crucial that you follow safety precautions to avoid serious implications. Wearing contact lenses past their expiry date can increase the risk of eye infections, which, in turn, can worsen and cause vision impairment.

The same applies to the cleaning solution. Make sure that you replace it after reaching the expiry date.

12) Will reading in dim light damage my eyes?

Reading is a precision activity, and when you do it under dim lighting, you increase strain to your eyes. As a result, you can suffer from symptoms such as eye redness, itchiness, pain, and dryness. The best practice is to read under bright lighting.

13) How to avoid eye injuries?

Eye injuries cannot be completely avoided. However, you can take steps to drastically lower the risks. For example, wear a protective eyewear when working at the workshop or travelling outdoors.
