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.

Everyday Habits That Are Hurting Your Vision

The eyes are major organs and they need proper care and attention. However, often people take their vision for granted – they do things that might be damaging their vision. As one of the top eye hospitals in Kolkata, we discuss with you a few everyday habits that can hurt your vision and cause eye discomfort, pain, and even eye infection. 

Everyday Habits That Are Hurting Your Vision

Habit 1: Rubbing your eyes: 

  • This may seem like a harmless thing to do, but rubbing your eyes vigorously can actually affect your eye health.
  • When you rub your eyes, there is a chance of keratoconus – which can weaken the structure of the cornea. 
  • Every day your hands come in contact with many bacteria and germs. When you rub your hands with dirty hands, you increase the risk of transferring the germs into your eyes, thus increasing the risk of eye infection.

Habit 2: Too much screen time:

  • Staring at digital screens all day can cause eye discomfort.
  • During the  Covid-19 pandemic, the digital screen timings have increased as education, work and entertainment have moved online.
  • According to a study, nearly 23% of the Indian population saw their eyesight weakening due to the increased screen time during the pandemic. The study found that in 2020, the average Indian spent around 6 hours 36 minutes staring at a digital screen. 
  • When you are spending too much time on TV, browsing the internet, or staring at your phone, you’re less likely to blink, which means your eyes can get dry, red and itchy. 
  • To avoid dry and itchy eyes, follow the 20-20-20 rule. Every 20 minutes look at something 20 feet away for 20 seconds. 

Habit 3: Not wearing sunglasses outside

  • Extensive exposure to UV rays damages the retina, putting the eyes at the risk for eye conditions such as cataracts, macular degeneration, pterygium, and photokeratitis. 
  • Always buy sunglasses with UV protection.

Habit 4: Wearing old contact lenses or not storing them properly 

  • Wearing old contact lenses increases one’s risk of suffering from eye infections. 
  • Other reasons for eye infections include sharing contacts with others, sleeping in your contacts, and wearing ill-fitting contact lenses.
  • Store and keep your contact lenses in a hygienic way. Keep the case clean and replace the case every 3 months. 
  • Wearing contact lenses while showering or swimming can cause eye infections.

Habit 5: Using expired eye makeup

  • Discard expired eye makeup. Using expired or old eye makeup can lead to eye irritation and infection. 
  • Before applying an eye makeup product, always check its expiry date.

Habit 6: Skipping regular eye exams

  • Regular eye checkups can help in the early detection of eye conditions. Some eye conditions do not show any early signs and they can be detected only through comprehensive eye exams.

Note: If you are looking for a top eye hospital in Kolkata for an eye check-up, visit or book an online appointment with Disha Eye Hospitals.

Habit 7: Uncontrolled smoking

  • Smoking is injurious to health. It can cause health problems such as cancer or lung disease and can also harm your eye health. 
  • A few of the eye conditions related to smoking are glaucoma, cataracts, dry eye, and macular degeneration. Gradually quitting smoking can help save your vision as well as your overall physical health.

A useful guide on LASIK

A type of refractive eye surgery, LASIK stands for laser-assisted in situ keratomileusis. The procedure can correct refractive errors — nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. As the surgery has a good track record, it is often chosen by many patients. The procedure is safe and quickly restores the vision.

A useful guide on LASIK

Requirements for a good LASIK surgery candidate:

1. Candidate’s eyes should be healthy: The eyes should be healthy. If there’s any active eye infection or abrasions, they must be treated before the surgery.

2. The eye condition is within range: LASIK eye procedures treat a wide range of eye conditions, including hyperopia, myopia, astigmatism. An eye doctor is the best person to tell whether LASIK is the best treatment for a particular eye condition or not.

3. The vision should be stable: Stable vision reduces the risk of regression and the need for a touch-up procedure. 

4. The candidate should be an adult: The patient has to be at least 18 years old to undergo LASIK surgery.

What is the procedure for LASIK?

Before a LASIK procedure, the eye surgeon will/may:

  • Assess the overall health of the eye. 
  • Prescribe mild medication a few days before the procedure. 
  • Put numbing drops in the eyes before the operation starts.

LASIK treatment:

LASIK surgery can be performed with Excimer Laser as well as Femtosecond laser. While the former uses a blade during the procedure, the latter is a bladeless procedure.

The laser physically corrects the glass prescription by reshaping the cornea during the surgery. Thus, correcting myopia, hypermetropia or astigmatism using this technology.

The LASIK surgery usually requires less than 30 minutes of operating room time. The laser is for less than a minute on each eye. However,  preoperative preparation and post-operative observation may take hours.

LASIK with Excimer Laser

The procedure involves two steps:

  • Creation of thin-film or flap on the surface of the cornea by a precision flap-making instrument
  • Reshaping the cornea with excimer laser by removing tissue from the middle layer of the cornea

The procedure in detail:

  • After numbing the eyes, the patient is asked to relax on the treatment bed. The eyelids of the patient are held open with a precision flap making instrument, microkeratome. It is an extremely fine instrument with precise delicate gears.
  • The patient is then asked to focus on a special fixation light. The eye surgeon uses a precision instrument. The instrument folds away a corneal flap within seconds, revealing the middle layer of the cornea.
  • During the creation of the flap, the pressure in the patient’s eye rises and their vision may grey out.
  • The cornea is reshaped using an excimer laser. 
  • After this, the flap is returned to cover the exposed area. And the treatment is completed.
  • Eye drops are put in the eye and a shield will be placed to keep the eye protected.

LASIK with Femtosecond Laser

The following steps are followed on the day of surgery: 

  • The patient is brought to a procedure room and is asked to lie on their back under the laser system and a computer screen.
  • Numbing drops are put into the patient’s eyes. 
  • The patient’s eyelids are kept open during the procedure using a machine called eye speculum.
  • A suction ring is centered over the pupil and suction is applied. A glass lens holds the globe of the eye steady and flattens the cornea.
  • The laser is used to create a flap in the surface of the cornea and suction is released.
  • The cornea is reshaped as required.
  • The flap is replaced once reshaping is complete. 
  • The flap will heal without stitches.

Note: If you are looking for the best eye hospital in Kolkata for bladeless, femtosecond LASIK surgery, you can visit us. We, at Disha Eye Hospitals, are committed to providing our patients with the highest possible standard of ophthalmic care in an affordable manner. Along with LASIK surgery, a few of our other services include cataract surgery, glaucoma treatment, diagnostic and imaging services.

Although each of the LASIK procedures has its own features and benefits, there are a few advantages of femtosecond laser LASIK:

  • Puts patients at greater ease as no blade is used during the process
  • The decreased potential risk of corneal abrasion
  • Helps surgeons to customize LASIK procedure
  • Creates corneal flap with edges, enabling it to fit securely in place after the LASIK procedure, decreasing the risk of dislocation of flap post-surgery

What to do after LASIK surgery?

After LASIK surgery:

  • The patient should avoid rubbing or squeezing their eyes for the first week. 
  • They should take care of the eye to ensure that they do not displace the flap.

Why are dry eyes an increasing problem?

If you’ve ever experienced irritation, itching, or scratching sensation in your eyes,  you are not alone. These are the symptoms of dry eyes. Dry eyes is an eye syndrome that occurs when tears fail to provide adequate lubrication to the eyes. 

Why are dry eyes an increasing problem

Dry eyes may sting or burn. In some cases, dry eyes are uncomfortable, disrupting day-to-day activities. Dry eye syndrome is on the rise, affecting around 344 million people across the globe. 

Note: We, at Disha Eye Hospitals, are equipped with state-of-the-art diagnostic equipment to help diagnose and treat dry eye syndrome. We have some of the best doctors, ophthalmologists, and eye surgeons in Kolkata on board .

Causes of dry eye: 

  • Weather conditions: Different weather conditions, such as cold climate and exposure to winds can result in tears evaporating too quickly, further leading to dryness in the eyes. Dry air can also lead to dry eyes. 

 

  • Air conditioning: Today, air conditioners have become a part of homes and offices, especially in areas with high humidity. While air-conditioned homes and offices make your indoor environment more pleasant, it also drains the humidity from the air, resulting in loss of moisture in the eyes. This can result in dry eyes. 

 

 

Extended screen time: One of the noticeable and recent effects on eye health is extended screen time. Blinking helps in keeping the eyes lubricated. When people look at a screen for extended periods, they tend to blink less. This causes faster evaporation of the film of tears that protects the surface of the eye, leading to dry eyes. 

 

Wearing contact lenses: Contact lenses can also put one at risk of dry eyes. Wearing contact lenses for more than the recommended hours per day can increase the risk of developing dry eyes.   Not handling contact lenses properly can result in dry eye issues and can also exacerbate dry eye symptoms for those who are already suffering from the condition.

Things to know about an eye strain headache

People often experience eye strain. The term is often used by people to describe symptoms such as mild pain or discomfort in the eye. Usually, eye strain occurs when your eyes get tired due to overuse, such as driving for a long period of time or staring at the computer or mobile screen for too long. This can cause discomfort.  Eye strain is also known as asthenopia or ocular fatigue. Eye strain can sometimes also trigger headaches, the severity of which depends on the cause. They are known as eyestrain headaches. 

eye strain headache

Eye strain headaches are basically the pain behind one’s eyes. Below we share a few signs of eye strain headache:

What are the signs of eye strain headache?

  • Dry eyes
  • Sensitivity to light
  • Blurry vision
  • Sour eyes
  • Watery eyes
  • Neck, shoulder or back pain

What causes eye strain?

  • Continuous use of the digital screen: Staring at a digital screen for a long period of time is the most common cause of eye strain. 

When you focus on the screen, you blink less often, which can lead to dry eyes and cause irritation  

  • Prolonged focus on a single task: Your eyes get tired when you continually focus on a single activity for a long time, for instance, driving, reading a book or even drawing.

 

  • Vision problems:  You may experience eye strain if you have vision problems. When you have problems such as nearsightedness or farsightedness, your eyes work harder to see things, making the eyes tired and leading to an eyestrain headache. 

 

 

  • Bright or dim lights: If the light is too bright or too dim, it is difficult to see clearly. Trying to focus in such situations is tough, making your eyes tired and strained.  

How to prevent eye strain?

  • Follow the 20-20-20 rule:  Try to take frequent breaks when using digital screens. According to this rule, look at something at least 20 feet away for around 20 seconds every 20 minutes.
  • Avoid using digital screens in the dark: Your eyes need to do extra work when you stare at a digital screen in the dark, making your eyes tired sooner than they should. Therefore, avoid using a digital screen in the dark.
  • Blink often: Blink more than you do now.  Blinking moisten your eyes, keeping the risk of dry eyes away.
  • Keep your screen at a distance: Always  your screen at least 25 inches away from your eyes and position it slightly below eye level.
  • Do not wear eye contact lenses for a longer period of time: Wearing contact lenses for a long time can cause eye irritation and strain your eyes. 
  • Adjust the brightness of your digital screen: Make sure that your screen is bright enough to not have shadows, and also not too bright that it’s hard to discern contrast.
  • Keep your surroundings clean: Keep your surroundings free from dust, which can disturb your tear ducts and lead to dry eyes.
  • Get enough sleep: Try to get around 6-8  hours of sleep. Stay hydrated and drink up liquids to avoid dry eye discomfort.
  • Wear anti-reflective lenses: The best way to save your sensitive eyes from eye strain from digital screens is to wear anti-reflective glasses. 
  • Get regular eye checkups: Weak vision can cause headaches, eye strain and blurred vision. So, even if you don’t have any eye problems, you should visit an eye specialist and have your eyes examined at least once a year.

Cataract Surgery And Your Options

Cataract surgery is one of the most common and safest surgeries performed around the world. Approximately, 10 million cataract operations are performed each year in the world with a high success rate.

What is cataract surgery?

Cataract surgery is the procedure of replacing the lens of your eyes with an artificial lens. A cataract is clouding of the natural lens of the eye. The surgery is carried out to remove the damaged lens and replace it with an artificial lens. It is usually performed under local anaesthesia  where the patient will be awake but will not feel any pain during the procedure. 

Cataract surgery and your options

Benefits of cataract surgery 

1. Improves vision

2. Helps in seeing things in focus

3. Improves the quality of life

4. Protected eye health

Here we have shared a few things you should consider while opting for cataract surgery:

 

  • Deciding on the time for surgery: Cataracts are removed when it makes it difficult for the person to carry out normal activities, such as driving or reading. An ophthalmologist is the best person to suggest the best time for surgery.
  • Pre-operative assessment: An eye doctor carries out a pre-operative assessment before the surgery.

1. The general health evaluation of the patient includes checking the patient’s blood pressure levels, current medication, allergies, and other medical conditions. 

2. The doctor will further check the visual acuity of the patient. The refractive errors, dioptric error, and intraocular pressure of the eye are also measured before the surgery. 

 

  • Choosing the type of intraocular lens: Another option you need to consider for your cataract surgery is the type of intraocular lens (IOL). The doctor will remove your natural lens and replace it with any of these types of IOLs:

 

 

1. Monifocal lens

2. Multifocal or accommodative lens

3. Toric lens

What you should know about care after glaucoma surgery?

Glaucoma is a condition that occurs when the pressure in the optic nerve is abnormally high. The increased pressure in the eye can damage the optic nerve. If left untreated for ling, glaucoma can cause permanent vision loss. Glaucoma surgery is done to reduce the ocular pressure by creating a separate pathway and allowing fluid to drain more easily. As the eyes are delicate organs, they need extra care, especially after a surgical operation such as glaucoma surgery.

eye specialist

Here our eye specialists share with you some useful insights on glaucoma surgery:

What to Expect After Glaucoma Surgery?

A patient is likely to experience mild discomfort after glaucoma surgery. However, the overall health of the patient plays an important role in the recovery process. The full recovery from the surgery takes around a period of one month. It is common for a patient to experience blurred vision or minor discomfort. It may also cause poor eyesight that can last a few days. However, it is important to consult the concerned eye specialist, if someone experiences any sudden loss of eyesight during this time. Loss of vision can be a sign of a complication that may have occurred as a result of surgery.

 

Things you should know about care after glaucoma surgery

  • Do not drive: It is advisable to not drive while recovering from glaucoma surgery. It is important to ensure that the patient has someone to drive home after surgery. This goes with the follow-up check-ups as well. 
  • Take proper rest: Take plenty of time to relax and heal while recovering. Do not participate in any sort of strenuous exercise. It is recommended to take some time off work if the job involves physical labour. 
  • Take time off from eye-intensive jobs: Any intricate tasks such as reading, writing, or typing should also be avoided in the process of healing. This will prevent the eyes from extra stress. 
  • Follow doctor’s instructions: A successful recovery from any surgery depends on proper post-operative care. The eye surgeon may ask the patient to wear padding to protect the eyes. It is important to keep it on until the doctor’s next instruction. Moreover, to ensure a successful recovery, eye drops should be taken properly. 
  • Follow-up appointments: The follow-up appointments will determine if the healing is happening properly. It will also detect if there are any signs of infection. The patient also may need to have new corrective glasses as recommended by the doctor. 
  • No rubbing of eyes: It’s important not to rub or touch your eyes if there is any discomfort in the eyes. It can have damaging effects on the eyes. 
  • Wash your hands before using eye drops: It is important to wash hands with soap and warm water before using eye drops. Moreover, there will be strict instructions from the doctor on when the patient will be able to shower. 
  • Wear protective eyewear if recommended: The doctors may advise using protective eyewear. Especially during summer, it is important to wear protective gear to prevent the damaging effects of the sun’s rays.

Though there is no cure for glaucoma, it can be managed effectively. Disha Eye Hospitals provide quality eye care  with a team of best eye specialists on board, specialized in treating eye conditions such as glaucoma, cataracts, diabetic retinopathy, and corneal diseases.

What is retinal artery occlusion?

A very rare eye condition, retinal artery occlusion (RAO) is an ophthalmic emergency, which often results in acute vision loss. In the United States, the incidence of vision loss due to retinal artery occlusion is 1 to 2 cases per 100 000 per year. The patient with RAO requires prompt medical attention and should be transferred to a stroke centre. Retinal artery occlusion refers to the obstruction or blockage of blood to the retina of one eye, causing vision loss.

As a leading eye hospital in Kolkata, we share with you insights on this rare eye disease.

eye hospital

What are the risk factors?

Anyone who is old or has other medical conditions such as diabetes, glaucoma, high blood pressure are at higher risk to have RAO. Here we have listed down a few of the risk factors:

  • Old age
  • High cholesterol 
  • Male 
  • Heart disease
  • Smoking
  • Damage from radiation treatments 
  • Birth control pills
  • Hypertension
  • Obesity
  • Cardiovascular disease

Symptoms of retinal artery occlusion:

One of the main symptoms of eye stroke or retinal artery occlusion is a sudden painless change in vision. It often happens in only one eye. 

Apart from a sudden change in vision, one may notice the following signs or symptoms:

  • Blurry or distorted vision
  • Blind spots
  • Sudden blindness of one eye

How is the eye condition diagnosed?

  1. The condition is diagnosed by a dilated eye examination. 
  2. The retinal artery occlusion is an area with retinal whitening along the blocked blood vessel. This whitening lasts for around 4 to 6 weeks before it starts fading away.
  3. Fluorescein angiography is employed to record the blood flow in the retina. It shows a delay in filling the retinal arteries.  
  4. Optical coherence tomography gives detailed images of the central retina. It shows the swelling in the inner layers of the affected area. 
  5. The eye doctor may check the other medical conditions of the patient that are related to retinal artery occlusion.

Treatment for retinal artery occlusion:

Retinal artery occlusion has no clinically proven treatment. However, several therapies are used to treat RAO, including:

  1. Hyperventilation— In this therapy, the patient is made to inhale carbogen — a mixture of oxygen (95%) and carbon dioxide (5%). Through this, the eye doctors attempt to dilate the retinal arteries and make the blood clot move.
  2. Paracentesis: In this procedure, fluid is removed from the front of the eye using a small-gauge needle. It is done to lower the intraocular pressure to further dislodge the blood clot.
  3. Using different medications to lower the intraocular pressure.
  4. Giving an ocular massage with a thumb to move the embolus.

26 Insights curated by a leading eye hospital in West Bengal

Eyes are one of the most vulnerable and complex parts of the human body. Healthy sight lets us see the world, yet many of us take it for granted. It is estimated that  half a million blinding injuries occur every year across the world. Exposure to chemicals, dust, rust, and debris can cause eye injuries, and unfortunately some result in permanent blindness. 

leading eye hospital in West Bengal

As one of the leading eye hospitals in West Bengal, we have curated a list of 26 insightful tips on eye protection:

People working in factories:

1.If you are working in a factory, wear the right protective eye equipment (PPE).

2.There are four primary types of eye protectors: general safety glasses, laser safety glasses, chemical splash goggles, and impact goggles. You should know which ones to use when and how to wear the protectors properly.

Gardening:

1.Never spray insecticides or pesticides when there is a breeze blowing. These chemicals can go into your eyes and cause eye problems that can lead to blindness. 

2.Wear eye-protective goggles while doing any kind of gardening job. Always wear polycarbonate goggles or safety spectacles, which are lightweight, durable, and offer better clarity of vision.

People spending a lot of time under the sun:

3.Always wear sunglasses with ultraviolet protection as UV radiation can damage the structure of the eye.

4,Try to stay in the shade when the UV rays of the sun are at their strongest, usually between 10 am and 4 pm.

5.Always apply sunscreen near your eye area 15-30 minutes before heading out in the sun.

6.Always try to protect your eyes from all angles. Wear sunglasses that wrap all the way around the eye temples.

Working in offices:

7.Your desktop or laptop screen should provide a clear and sharp image.

8.The font size should be suitable for reading.

9.The distance between your eyes and the computer screen should be around 350 – 600 mm for comfortable viewing.

10.The computer screen should be adjustable to tilt according to your needs.

11.Keep blinking intentionally to keep your eyes moisturised.

12.The keyboard should be detachable, so that you can keep changing your postures frequently and also work from a distance.
