Can Cataract affect children?

Cataracts are often associated with ageing. Most people start getting cataracts around age 40 and symptoms appear as they age. Although very rare, children can get cataracts too. It is either present at the time of their birth or can happen due to some medical conditions.

Cataracts in children can be:

  • Unilateral – Affect one eye
  • Bilateral – Affect both eyes

First, let us understand what cataracts are.

  • What are cataracts?

The clouding of the natural lens of the human eye is known as cataract. Seeing through cloudy lenses leads to blurry, unclear vision. For the eyes to see, the light rays pass through the lens and focus on the retina. With cataract, the eye lens becomes foggy, for which it cannot focus on the light in the same way.

 

  • Can cataracts affect children?

Yes, cataracts can affect children. Although it is very rare, some are born with cataracts. They can also develop cataracts at a very young age, which are known as childhood cataracts. 

  1. Congenital cataracts: Some children are born with cataracts, or may get them in childhood. This type of cataract mostly happens in both eyes and can affect the child’s vision. 
  2. Secondary cataracts: These cataracts form due to some other medical conditions. For instance, other eye problems, diabetes or even due to medicines. 
  3. Traumatic cataracts: Some cataracts happen due to eye injuries. A child may get cataracts directly after hurting the eye or can occur many years later.
  4. Radiation cataracts: Sometimes a child may get cataracts due to their exposure to some types of radiation.
  • What are the causes of cataracts in a child?

Some of the causes of cataracts in a child are:

  • Genetic fault inherited from parents
  • Certain genetic conditions 
  • Infections picked up by the mother during pregnancy
  • Eye injury after birth

 

  • What are the symptoms of cataracts in children?

Here are a few symptoms of cataracts in children: 

  • Misaligned eyes
  • A pupil that appears to be white when a flashlight is shined ito it
  • Eye movements that cannot be controlled
  • Blurry vision
  • Trouble seeing
  • Seeing a halo around an object

 

  • How is cataract treated in children?

  • Age
  • Symptoms 
  • Health condition
  • The severity of the condition

The eye care doctor of the child will decide upon what treatment should be given to them. They may prescribe the child to:

  • Wear glasses or contact lenses

Paediatric Refractive Errors: what you need to know as parents?

If you notice your child having trouble reading or sitting too close to the television, you should consider taking him or her to an eye doctor. These along with eye rubbing, squinting and lack of interest in school are often seen in children with refractive errors. Poor vision in one or both eyes during childhood can lead to the condition known as lazy eye that can cause long-term problems with your child’s vision. Here are some important things that you as parents should know about pediatric refractive errors and how they can be corrected:

Importance of healthy eyes for children 

Healthy eyes and vision are extremely crucial for children. Good vision not only aids in reading, but is equally important for performance in co-curricular activities in school.

What are refractive errors?

A type of vision problem, refractive errors cause blurred vision in children as the shape of the eyes keep the light from focusing images on the retina. The most common type of refractive errors are: 

  • Farsightedness (hyperopia)
  • Nearsightedness (myopia)
  • Astigmatism

If these conditions are not corrected, they can have harmful consequences for your children.

Here we discuss in detail the common refractive errors:

Farsightedness or hyperopia

Children with hyperopia find it difficult to focus on objects close to them. However, they can clearly see faraway objects.

Symptoms: 

  • Trouble seeing objects up close 
  • Squinting the eyes a lot

Nearsightedness or myopia

Children with myopia cannot focus clearly on distant objects. Nearsightedness is the most common refractive error that is seen in children. Parents should know that young children may not be able to tell that they cannot see properly or may be they are unaware.  It is therefore important for parents to observe children and take them to an eye doctor if they are sitting too close to the TV or holding books up close in the face. 

Symptoms

  • Rubbing eyes
  • Sitting too close to the TV
  • Excess watering of eyes
  • Squinting

Causes

The length of the eyeball grows longer than usual. 

  • The cornea is too curved. 

Astigmatism

Astigmatism causes blurred distance and near vision.  In many cases, astigmatism begins in early childhood.

Symptoms 

  • Distorted vision
  • Eye strain
  • Difficulty with night vision
  • Eye rubbing
  • Trouble reading

Causes

  • Astigmatism occurs when the cornea or the lens of the eyes have an irregular curve.

How to correct the refractive errors?

Treatment for refractive errors include 

  • Prescription eyeglasses 
  • Prescription contact lenses
  • Refractive laser eye surgery

Your eyesight: 12 common vision myths

You may have heard all sorts of things about what is good and bad for your eyes. From walking on the green grass to eating carrots for better eyesight, there are many things that people. But is there any truth in these?  

12 common vision myths

Here we debunk the most common vision myths:

Myth 1: Wearing glasses all the time can do more harm than good

Fact: Contrary to popular belief, wearing eyeglasses does not damage your eyes. There are eye conditions such as nearsightedness which may get worse over time but it has nothing to do with wearing glasses all the time.

Myth 2: Staring at the computer screen all day can damage the eyes

Fact: Just working on a computer and staring at the screen does not damage the eyes. However, working long hours on the computers and not blinking can make the eyes feel tired. A combination of factors such as poor lighting, poor posture, and viewing a computer at the wrong distance and angle can contribute to eye strain. Therefore, it is important to give rest to the eyes every 20 minutes while working on a computer. It is recommended to sit up straight and keep the computer at arm’s length.

Myth 3: Walking on green grass with bare feet benefits eyes

Fact:  It is believed by many people that walking barefoot on green grass is beneficial for the eyes. But there is no scientific evidence to back this statement. It neither benefits nor harms the eyes. 

Myth 4: Carrots help improve eyesight

Fact: Any discussion on health seems incomplete without carrots. Yes, carrots are loaded with Vitamin A which is an essential nutrient for eye health. But it doesn’t necessarily give you the entire amount of Vitamin A needed by your body. Therefore, eating only carrots will not help. Consume other foods which are high in Vitamin A such as milk, egg yolks, oily fish, leafy greens for proper intake of Vitamin A. 

Myth 5: Not everyone gets cataracts.

Fact: Though cataracts are a part of the aging process, they can occur at any age. 

Myth 6: Eyes are fully grown at birth.

Fact:  It takes up to two years for a baby’s eyesight to fully develop. In fact, the eyes continue to grow over the course of a lifetime. 

Myth 7: Eye exams are unnecessary unless there is an eye problem.

Fact: This is the most dangerous myth that restricts people from going for regular eye checkups. There are eye issues that get revealed only during a routine examination. No matter how old or young you are, conditions such as glaucoma can only be detected and managed properly, if you sign for an eye check-up at least once a year. 

Looking for the best eye doctor in Kolkata?

At Disha Eye Hospitals, you can consult the best eye doctors in Kolkata. We offer laser treatment, refractive surgery, glaucoma treatment, cataract surgery, and many other services to help you get through your eye issues. 

Myth 8: Faulty movements can give crossed eyes

Fact: This is yet another misconception. Crossed eyes are a result of nerve damage. Since our eyes are designed to move in all directions,  do not be scared the next time you pull a funny face. 

Myth 9: Sungazing can improve eye health

Fact: Looking at the sun even for a short time can be harmful to your eyes. It can damage the retina permanently and even cause blindness.

Myth 10:  Losing vision is an inevitable part of ageing.

Fact: If detected earlier, many vision problems could be treated successfully. The key here is to have regular eye exams.  

Myth 11: People with diabetes will eventually lose eyesight

Fact: People with can prevent vision loss by keeping blood sugar levels under control. 

Myth 12: Vision Loss is genetic

Fact: It is commonly believed that if the parents never had an eye problem, the children are immune to vision issues. In reality, there is no guarantee of assured vision immunity. Vision problems may happen to anyone.

Difference between an Ophthalmologist, Optometrist and Optician

 

If you ever had to search for an eye care provider, there are chances that you stumbled upon three words: Ophthalmologist, Optometrist and Optician. Each of these eye care practitioners plays a significant role in maintaining your eye health. However, you must understand their individual significance before deciding whom to approach and when.

As a leading eye hospital, we have listed down the difference between the three types of eye care providers:

Difference between an Ophthalmologist, Optometrist and Optician

1.Ophthalmologist: An ophthalmologist is a medical doctor who provides complete eye and vision care services. The services include diagnosis and treatment of eye problems due to other health conditions, medical and surgical eye care, and plastic surgery near the eye area. What makes an ophthalmologist different from an optometrist and optician is their level of training. As a medical doctor, an ophthalmologist undergoes extensive training and is authorised to practise medicine and surgery. They can also prescribe and fit eyeglasses and contact lenses to correct a patient’s vision problems.

Here are some suggestions for questions you can ask your ophthalmologist during an eye examination:

  • Can you let me know what eye tests should be done?
  • What is the cause of my vision loss?
  • Do I have peripheral field loss?
  • How is my eye condition? Is it stable? 

Why would you be referred to an ophthalmologist?

You will be referred to an ophthalmologist if the optometrist who did your eye examination finds signs of any eye condition. He or she will refer you to an ophthalmologist who specializes in eye conditions and diseases.
Note: If you are looking for the best eye doctor in Kolkata, visit our Disha Eye Hospitals. Our eye specialists specialize in diagnosing and treating several eye conditions such as glaucoma, corneal diseases, retinal conditions, cataract, and many other conditions.

2.Optometrist: An optometrist is a primary eye care professional who is trained to examine the eyes, detect any defects, provide low-vision aids and therapy, and prescribe and fit eyeglasses and contact lenses. They focus on the regular vision care of the eyes. 

Here are some suggestions for questions you can ask your optometrist:

  • What eye tests will you be running?
  • What do my symptoms mean? Is there any eye condition?
  • How do I maintain and monitor my eye health?
  • What are the treatments for my eye condition?

What can an optometrist diagnose?

An optometrist can find out about your health problems by examining your eyes. Along with diagnosing the eye problem, he or she can also treat the eye condition caused due to conditions such as diabetes, hypertension and others.

3.Optician: An optician is a trained technician to design, verify and fit your eyeglasses and contact lenses to correct your eyesight. They are not doctors, they follow the prescription given by your ophthalmologist or optometrist. The optician is not permitted to carry out eye tests or to diagnose and treat your eyes.

Here are some suggestions for questions you can ask an optician:

  • What kind of tests are involved in the eye exam I am prescribed?
  • Where do I find information about eye health?
  • Am I safe to drive?
  • What are the treatments available for my eye condition?

What does an optician look for?

An optician tests the eyes on the grounds of their ability to focus, coordinate, and see depth and colours accurately.

 

FAQs On Eye Treatment in Kolkata

Our eye specialists are often asked questions such as why an annual eye examination is important or how diabetes affects eye health or how to avail the best eye treatment in kolkata. Here we have answered some of the most frequently asked questions on eye treatment that you might find useful:

  • Why are annual eye examinations important? Eye conditions such as cataracts, diabetic retinopathy and glaucoma do not show any early symptoms. During a comprehensive annual eye exam, an eye doctor evaluates the health and condition of the eyes, giving you a better chance at getting the treatment at the right time. Certain conditions cannot be reversed but their progress can be slowed down with the right treatment. People suffering from diabetes and high blood pressure are often recommended to undergo frequent eye tests.
  • What is the most common eye treatment for refractive errors? Refractive errors are the most common type of vision problem. Refractive errors such as nearsightedness, farsightedness and presbyopia occur when there is a problem with the shape of the cornea and it cannot focus light accurately on the retina. Eyeglasses are the simplest and safest way to correct refractive errors. Some people also get refractive surgery like LASIK surgery done to change the shape of the cornea and reduce dependence on eyeglasses or contact lenses.
  • What is diabetic eye damage and can it be reversed? High blood sugar levels are not good for your overall health and your eyes are no exception. High blood sugar can lead to eye conditions such as blurry vision, cataracts, glaucoma and diabetic retinopathy. According to a study, diabetes is the primary cause of blindness in adults. Diabetes damages the blood vessels in the retina. The damage cannot be reversed but by seeking timely treatment the condition can be slowed down.
  • How to prevent diabetic eye conditions? If you are diabetic, get a comprehensive dilated eye examination at least once a year. Control your blood sugar, blood pressure and cholesterol levels. Try to quit smoking. If you smoke, your risk of diabetes-related eye diseases is higher. Exercising regularly is good for your eyes as it helps you keep your blood sugar, blood pressure and cholesterol levels in check.
  • How often should a child get his/her eyes tested? Infants should have their first eye exam at six months. Young children should have their eye tests latest by age three. Here’s a useful guide for parents on scheduling paediatric eye exams. In our Kolkata branch and other branches in West Bengal, we have highly experienced paediatric ophthalmologists who can help you ensure that your child’s eyes are developing normally.
  • What are cataracts and is surgery the best treatment option? Cataract forms when the proteins in the eyes clump together causing them to cloud the lens of the eye. As the condition advances, you may have problems with reading and driving at night. Cataract surgery is the best way to remove cataracts. During the surgery, the damaged lens is replaced by an artificial one.
  • Is there a treatment for glaucoma? Glaucoma is a condition that damages the eye’s optic nerve due to increased eye pressure. The condition worsens over time and can even lead to loss of vision. Though the damage caused can’t be reversed, treatment such as prescription eye drops, oral medications, laser treatment and surgery can help slow or prevent vision loss, particularly when the condition is detected in its early stages.

If you have any doubts or concerns about your eye health, get in touch with our eye specialists at Disha Eye Hospitals. They can help you maintain good eye health by advising you the right eye treatment plan.

 

 

 

 

Angle Recession Glaucoma: check out these insights curated by some of the best doctors in Kolkata

 

Angle Recession Glaucoma develops after an injury or trauma to the eye. In this type of glaucoma, the tissue in the eye’s angle is damaged, resulting in elevated pressure within the eye. This elevated eye pressure eventually damages the optic nerve resulting in angle recession glaucoma. Though this condition cannot be cured, there are many treatment options available to prevent loss of vision, if the condition is diagnosed early. Glaucoma can cause irreversible damage to your vision. Here are useful insights curated by some of the best eye doctors in Kolkata on angle recession glaucoma and what can be done to treat the condition: 

Glaucoma

 

Insight 1: An eye injury can lead to angle recession glaucoma 

When the eyes are healthy, clear fluid in them flows around the front part and drains through tiny canals near the outer edge of the iris. This spot is called the ‘drainage angle’. This continuous drainage of fluid keeps the pressure inside your eye at a healthy level. However, an eye injury can cause the fluid to build up – as a result, there is an increase in pressure inside the eye. This increasing pressure can damage the optic nerve causing blurry vision and light sensitivity.  However, not every injury leads to angle recession glaucoma. 

Insight 2: A blunt trauma is the most common cause of angle recession glaucoma 

A blunt trauma is the most common cause of angle recession glaucoma. Some of the most common types are: 

  • Sports injuries such as getting punched or elbowed in the eye or hit with an object in the eye
  • Car accidents that cause facial trauma
  • Physical assault
  • Severe falls
  • Industrial injuries

Insight 3: There may not be early warning signs 

There are no early signs of glaucoma. And, it is the same with angle recession glaucoma. The high eye pressure slowly damages the fibres in the optic nerve. By the time you will notice any change in vision, the condition would have worsened. Loss of peripheral vision is one of the most common symptoms of angle recession glaucoma. 

Angle recession glaucoma can develop even years after the injury. Some people even forget about the injury by the time glaucoma develops. It is, therefore, important to schedule annual eye exams with an ophthalmologist. This is all the more important if you have suffered an eye injury. You will be screened for angle recession and timely treatment can be started to protect your vision.  

Insight 4: For diagnosis, eye pressure and drainage angle needs to be checked 

The two most common tests that your ophthalmologist will conduct to check for glaucoma are — tonometry and gonioscopy. Tonometry is done to determine the pressure inside the eye while gonioscopy helps to check the drainage angle of the eye. The eye doctor may also ask you to get 

a visual field test to check the peripheral vision for losses you may not have noticed yourself. 

Insight 5: Glaucoma damage cannot be reversed but more vision loss can be prevented

The damage caused by glaucoma cannot be reversed. However, by seeking  timely treatment, further damage can be slowed. The severity of the eye injury will decide the course of treatment. Some of the treatment options are: 

  • Medication: Prescription eye drops medications lowers the amount of fluid and, thus, lower eye pressure. Usually, eye doctors prescribe the medications and monitor the eye pressure every month. 
  • Laser treatment: Laser treatment may be recommended when the medications are not effective at lowering excessive eye pressure. 
  • Surgery: In some cases, surgery may be suggested. During the surgery, a new opening in the white of your eye is created. This opening allows fluid to drain and this reduces eye pressure. 

Insight 6: To prevent angle recession glaucoma, protect your eyes from injuries 

Angle recession glaucoma may not be entirely preventable in every case. But you can reduce the risk by taking certain precautions such as wearing safety glasses when working with tools or when you play sports. 

 

What are pinguecula and pterygium? Important insights curated by a leading eye hospital

Different parts of the body often develop benign growths and eyes are no exception. Pinguecula (plural pingueculae) and pterygium (plural: pterygia) are harmless, non-cancerous growths that develop on the eye’s conjunctiva, the connective tissue that covers the white part of the eyes. While the two may appear similar and have similar symptoms and causes, they are actually quite different. 

As a leading eye hospital, we share with you some important insights on pinguecula and pterygium – 

  • Pinguecula is a non-cancerous lump 

A pinguecula is a non-cancerous lump on the white part of the eye. Overexposure to the sun and ultraviolet radiation are the most common reason for the development of pinguecula. The yellow lump typically grows on the side of your eyeball closest to the nose. Made of protein, calcium and fats,  the lump can either be round or triangular in shape. Pingueculae can cause discomfort but doesn’t affect the vision: 

  • Pingueculae part of normal ageing 

Though Pingueculae can develop at any age, it is common among middle-aged and elderly people. It is in fact a normal part of ageing. 

  • Pingueculae and pterygia are not the same thing 

A Pinguecula should not be confused with a pterygium . Pterygia occur when a Pingueculae grows and turns into a pterygium, a benign fibrous growth. Pterygia are more likely to interfere with normal sight. A pterygium is more noticeable than pinguecula. When pterygium extends onto the cornea far enough it can cause blurred vision as the curvature of the cornea is changed. Pterygium may also disrupt the distribution of tears across the surface of the eye, creating a feeling of dryness. 

  • The main symptom of  Pingueculae is yellow bump 

Besides the yellow bump, people who develop Pingueculae experience mild symptoms such as:  

 pinguecula

  1. Irritation
  2. Dry eyes
  3. Redness
  4. Swelling around the eyes
  5. Burning sensation
  6. Foreign body sensation
  7. Blurry vision
  8. Discomfort when wearing contacts
  • Pingueculae can lead to astigmatism 

Pingueculae changes the natural curve of the eyeball – which  can lead to astigmatism, a refractive error.  Astigmatism can be corrected with specialised contact lenses or laser eye surgery.

  • Overexposure to the sun causes Pingueculae and pterygia

Overexposure to the sun’s UV rays are likely the cause of pingueculae and pterygia. According to 2019 study, Pingueculae are more common in people who live in countries near the equator, where the sun’s rays are strongest. Besides the sun exposure, Pingueculae may also develop due to regular irritation from wind, dust or other airborne particles. 

  • Pingueculae may not require treatment 

In most cases, pingueculae do not usually require treatment. OTC or prescription medications often help people get relief from symptoms such as itchiness, irritation and dryness. Surgery is usually reserved for cases where severe eye irritation is noticed. However, some people wish to get their pingueculae or pterygia removed surgically for cosmetic reasons.  

  • To avoid Pingueculae protect eyes from the sun 

As sunlight and UV rays are among risk factors for developing pingueculae, you should take care of your eyes when stepping out. Wear the right sunglasses when out in the sun. Choose sunglasses that block both UVA and UVB rays. Wear a wide-brimmed hat to keep the sun’s rays off the face and eyes. If you spend a lot of time outdoors or in a dusty area, wear protective eyewear to prevent irritants from entering your eyes.

If you experience any eye problems, see an eye doctor immediately. At Disha Eye Hospitals, we are committed to providing quality eye care at affordable cost to people from all walks of life. From vision correction surgery to cataract surgery, we offer a wide range of services. 

Retina FAQ: A guide curated by some of the best retina specialists in Kolkata

The retina is an essential part of your vision as it’s responsible for turning light rays into images through signals to the brain. When there’s a problem with the retina, you run the risk of having vision problems. Our retina specialists in Kolkata, who specialize in diagnosing and treating retinal conditions such as diabetic retinopathy, age-related macular degeneration, and retinal detachment, answer some of the frequently asked questions on the retina:  

1.What is the retina? 

 

The retina is a layer of cells at the back of the eye. The job of the retina is to receive light, convert that light into a neural signal, and send the signal via the optic nerve to the brain. The brain interprets these signals and creates an image.

2.What are the different parts of the retina? 

The retina is nearly 0.5 mm thick and lines the back of the eye. It contains 200 million neurons and different parts of the retina are responsible for various vision functions. The macula is the most important part of the retina as it allows you to controls your central vision. It is the macula that allows you to see fine details, color, recognize faces and read.  and more.

3.What are the different types of retinal conditions? 

Some of the common retinal conditions are 

  • Macular degeneration
  • Diabetic retinopathy
  • Retinal detachment
  • Retinal tear.

There are other medical conditions that can occur, but these are some of the most common ones.

4.What is retinal detachment and what are the different types? 

Retinal detachment is a medical emergency. It occurs when the retina detaches and pulls away from its normal position. A detached retina doesn’t hurt but it may cause the sudden appearance of flashes of light and floaters. If immediate treatment is not sought, retinal detachment can result in permanent loss of vision. There are three different types of retinal detachment: 

  • Rhegmatogenous: This is the most common type of retinal detachment.  A tear in the retina causes the fluid to accumulate. The fluid pulls the retina away. The detached portions lose their blood supply, which results in loss of vision. 
  • Tractional: This type of detachment happens when the scar tissue grows on the retina’s surface. This type of retinal detachment is seen more commonly in people with uncontrolled diabetes. 
  • Exudative: In this type of retinal detachment, fluid accumulates below the retina, but there are no holes in the retina. Age-related macular degeneration, an injury to the eye or tumors are some of the causes of this type of retinal detachment. 

5.Is retinal detachment different from retinal tear? Both retinal tear and retinal detachment have similar symptoms. The retina could tear before it detaches.
