A step to prevent blindness

A group of eye conditions that causes damage to the optic nerves can be termed as glaucoma. Usually, the damage is caused due to high pressure in the eye. Glaucoma can cause permanent and irreversible loss of vision. Hence, it is also known as the ‘Silent Thief of Vision.’ 


Types of glaucoma
Glaucoma can be classified into three types that are:

1.Congenital or developmental glaucoma - a group of varied disordersHigh intraocular pressure is caused due to developmental abnormalities of the angle of the anterior chamber that obstructs the drainage of aqueous humor. 

2.Open-angle glaucoma - one of the common forms of glaucoma. There will be a slow increase of pressure in the eye that leads to loss of vision. The drainage angle that is formed by the cornea and iris will be open, whereas the trabecular meshwork will be slightly blocked. This causes pressure in the eye, which will slowly increase, leading to loss of vision.

3.Closed-angle glaucoma - also known as angle-closure glaucoma where the blockage is caused due to narrow angles between the cornea and the iris. The fluid cannot circulate through the eye, and pressure will increase. People with narrow drainage angles are more prone to angle-closure glaucoma.

Doctors recommend treating glaucoma at the early stages to preventd vision loss. The main concern is lower the eye pressure, and based on the situation, doctors would suggest eye drops, oral medications, laser treatment, and surgery. 

1.Eye drops - this is the first and foremost way of treating glaucoma. Based on the severity of the condition, the dosage differs among individuals. When identified in the early stages, eye drops can help reduce the pressure in the eye. 

2.Oral medications - oral medicines are prescribed by the doctors when eye drops alone cannot bring down the pressure in the eye.

3.Laser treatment - with the help of a small laser beam, the doctor will open the clogged channels in the trabecular meshwork.

4.Surgery - to control non-responsive glaucoma, doctors would suggest surgery. Along with Phaco IOL (intraocular lens implant), doctors would treat glaucoma by creating a new drainage channel in which the aqueous fluid can leave the eye and lowers the IOP (intraocular pressure). 

At Amrit Hospitals, doctors can help identify and diagnose glaucoma at the early stages to prevent vision loss with the help of the latest technologies.

Revital Vision Therapy for Amblyopia or Lazy Eye

Amblyopia or lazy eye  is a condition occurring when the brain and the eye refuse to work together. It mainly affects a single eye because one eye has a stronger focus than the other. So the brain cannot recognize the blurry vision and relies on the vision of the stronger eye that gradually worsens the vision of the weaker eye. Amblyopia is also called a lazy eye, and it mostly occurs in infancy, but sometimes it can occur in adults too.


  • An eye that wanders in and out (Strabismus).
  • Eyes that do not work together.
  • Double images.
  • Head tilting.
  • Poor depth perception.
  • Blurred vision.
Factors associated with an increased risk of lazy eye include:
  • Premature birth
  • Small size at birth
  • Genetics of the baby
  • Developmental disabilities

Types of Amblyopia:

There are three types of amblyopia 

1.Strabismic Amblyopia
Here to avoid doubled visions, the brain rejects or does not respond to the visual images of the weak eye that lead to strabismic amblyopia. 

2. Refractive Amblyopia
In some cases, amblyopia occurs due to unequal refractive errors in both the eyes despite its alignment. Here the brain relies on the eye that has the correct refractive index and rejects the blurred vision.       

3. Deprivation amblyopia
This is a lazy eye caused due to condition that rejects light from entering and being focused in a baby's eye, such as a congenital cataract. Prompt treatment of congenital cataracts is necessary to allow normal visual development to occur. 

Revital Vision Therapy
It is a program to improve amblyopia to upskill your brain to see better without auxiliary surgery, enhancements, drugs, or side- effects. It is feasible to enhance brain processing by efficacious visual stimulation of the neurons, which is at the helm for vision in the primary visual cortex, long after the critical period. 

RevitalVision's neural training program is clinically and scientifically proven, unlike eye exercise programs that focus on relaxing eye muscles. 

During training sessions, a series of visual tasks and repetitive images train the brain and improve visual processing. Revital vision analyzes performance and continuously adjust the individually customized training sessions to improve the vision substantially.

What is Age-Related Macular Degeneration?

AMD is one of the leading causes of vision loss. AMD destroys macula, which is apart of the retina, which provides sharp and focused vision. The condition develops as you age. 
macular degeneration treatment chennai

There are two main types of AMD:


1. Dry Form

Here we can see the presence of drusen (yellow deposits) in the macula. As the amount of drusen increases, it leads to distortion in vision. It can also cause thinning of the light-sensitive layers of cells of the macula, which may lead to the death of tissues, and gradual vision loss. 

2.Wet Form

This is more serious than the dry form. Here abnormal blood vessels are grown from the choroid membrane behind the macula. Your vision may get distorted because of the blood vessels leak, and the fluid enters into the retina. It can also lead to blind spots and loss of the central vision.

Symptoms of AMD


macular degeneration treatment in chennai

  • Blurry vision.
  • Straight lines look curved
  • Difficulty in reading.
  • Can not see details in low light.
  • Highly sensitive to glare.
  • Central vision will not be clear.

Risk factors

  • Age – It is the number one risk factor that leads to AMD.
  • Family history - children with parents suffering from AMD have an increased chance of acquiring AMD.
  • Smoking- anything which reduces oxygen supply to the retina can cause AMD.
  • Gender - Females are more likely to get AMD.
  • Too much exposure to the sun can lead to AMD.
  • Obesity.
  • Diet plays a vital role in developing AMD.
  • High blood pressure also restricts oxygen flow to the retina, thus leads to AMD.

Tips for Protecting Eye Health and Preventing Macular Degeneration

  • Eat a nutritious and healthy diet which includes green leafy vegetables, yellow and orange fruit, fish, and grains.
  • Try to maintain a healthy diet.
  • Quit the habit of smoking.
  • Your blood pressure must always be in control.
  • Wear sunglasses when exposed to the sun.
  • Consult an eye specialist for a regular eye examination.

Treatments for AMD


The treatment for early dry AMD is  good nutrition .You must have a healthy diet plan by including food which is rich in antioxidants that can keep the cells of macula healthy. Wet AMD can be treated with anti VEGF injection for regression of abnormal blood vessels . Sealing of the blood vessels associated with wet AMD can be done with a laser. Implantable Telescope Technology is another method of treating AMD Where they implant a tiny telescope which can help to improve your vision. Intake of certain vitamin tablets can also increase the quality of vision.

All You Need To Know About Cataract

Eyes are the most important organ of sense. But in spite of it being an organ that gives us the unmatched and unimaginable power of vision, we tend to neglect them.  Many issues strike the organ and some of them stand to be very severe. One such severe issue faced by people is a Cataract makes the vision blurry. It’s common among older people but people of other age groups get affected by this disease too.

 What can cause Cataracts?

Cataracts develop when there is a protein buildup in the lens of the eyes, preventing light to pass through the lens thus making the vision uncomfortably cloudy and blurry.  Some people are even posed with the threat of losing their eyesight due to cataract. This depends on the overall health condition of the patient and the type of Cataract he is affected. Different types of Cataracts are caused due to several reasons as follow:

  •     Age-related: A few cataracts are formed due to old age
  •     Congenital. Babies can be born with cataracts and even can be affected by the condition in their childhoods. This is known as congenital cataract.
  •     Secondary. If one is affected by medical conditions such as diabetes, he or she is more likely to get affected by secondary cataract. This can also be caused by being around ultraviolet light and toxic substances.
  •      Traumatic. As the name suggests, traumatic cataracts are formed as a result of some accident.
Along with these, there are various other reasons for getting a cataract that include smoking and drinking.


Cataracts take time to start affecting you and until it starts blocking light, it may not even come to your notice. But once it starts blocking the light you may notice a few symptoms as follow:
  •     Foggy, cloudy and blurry vision
  •     Colours may not seem the same.
  •     Night blindness
  •     One may have double vision
  •     Specs and contact lenses may not work effectively

How are Cataracts diagnosed?

Once cataract is suspected, the eye doctor prescribes tests to check the condition of the eye and the vision. He dilates the pupil to parts of the eye, especially the lens.


 Treatment of Cataract

Cataract can be cured by the use of corrected spectacles and contact lenses in a few cases. In other cases where these don’t work and cataracts have become major issues in one’s daily life, cataract surgeries can help.


Cataract Surgeries are done on an outpatient basis and it’s a quick and successful process. The surgery involves removing the original lens from the eye and replacing it with a man-made one.

Prevention is better than Cure

Cataract prevention is quite difficult as the reasons for cataract are very uncertain. Getting your eyes checked regularly, washing them with clean water and maintaining proper hygiene can reduce the risk of getting affected.

Be careful about Diabetic Retinopathy

    The growing statistics of people affected with diabetes is quite alarming these days. About one in every 5 of our elder population is has diabetes in some degree of intensity. The fact that diabetes has an increasing influence of eyesight and other eye related issues increases the gravity of the situation. 
    Studies show that people with diabetes are at a higher risk of contracting eye and vision problems that could eventually lead to blindness. With world class treatment and facilities, when it comes to the realms of eye care, Amrit Hospital offers one of the best diabetes and retina services in the world.
    Now, let us have a look into the various effects of diabetes on our retina and the conditions caused thereof. 
    Retina is the innermost layer in our eye that is responsible for receiving the light signals and transmitting it to the brain through optic nerves. Patients with diabetes are at an increased risk of the condition called diabetic retinopathy. They occur in two stages namely proliferative and non proliferative.

    Diabetic retinopathy does not usually manifest any symptoms in the early stages. However, with progress in time fluctuating, blurry and double visions might be encountered. Eye pain, cataracts and decrease in range of vision are some other symptoms of the condition
    Managing diabetic retinopathy
    • Diabetic retinopathy can be managed with the help of lasers as in photocoagulation and Anti-VEGF injection in some rare cases.
    •  Photocoagulation aims at protecting the central vision by direction laser beams to seal the leaking blood vessels in the retina. This laser treatment can be completed in about 3 sittings and helps in preventing further deterioration of vision. It does not help in restoring the lost vision, hence increasing the importance of an early detection of diabetic retinopathy.
    • Anti-VEGF agents are an evolving treatment methodology and involve intravitreal injection. They are mainly used in treatment of proliferative diabetic retinopathy. The earlier the diagnosis and initiation of treatment, better is the result. Hence it is advisable to get your eyes checked up in every 6 months, once diagnosed with diabetes.
    Amrit Hospital is one of the best eye care centres in Chennai, offering the latest technologies in the field.

    Lasik surgey: Experience Better Vision

    Bladeless LASIK is a refractive treatment surgery which treats surgical procedures of common vision problems such as farsightedness, nearsightedness, presbyopia, and astigmatism. Bladeless LASIK is also known as all laser LASIK or IntraLase. This LASIK surgery is different to other LASIK surgeries as this surgery is created flap by using a laser opposite to a manual blade. Bladeless LASIK is boon for the people with thin corneas as these people are not suitable for the general LASIK treatment due to its precision. Bladeless LASIK has a quality to consistently producing corneal flaps thin enough to treat people with thin corneas and an outpatient procedure.

    Lasik means laser assisted in-situ keratomileusis eye surgery that achieve 20/25 vision or better that is good for most eye activities. This technique is reducing the individual dependence on eyeglasses or contact lenses. The eye surgeon is capable to develop a tiny flap in the patient’s cornea, with the support of femtosecond computer technology. The laser operates at extremely high speed and permit tissue to be targeted and divided at the molecular level without heating or impacting surrounding tissues, with the control of the computer. The bladeless laser treatment creates corneal flap in much more precise manner in comparison to the traditional microkeratome blade. Further, a standard laser is used to make the appropriate adjustments. The surgery commonly takes less than five minutes and a painless process.

    Bladeless LASIK surgery supports surgeon to provide a more accurate and flap on the eye that will fall back into place naturally. The difference in flap structure created by the bladeless laser may reduce the chance of cells growing underneath and pushing up the flap (epithelial in-growth) to create an irregular corneal surface with accompanying vision defects. Sometimes, bladeless laser show light sensitivity as a side effect, but it can resolve soon. LASIK surgery also gives rare complications such as dry eyes or temporary visual disturbances. The bladeless laser surgery is as specific treatment facility and totally depends on the recommendation of the eye surgeon.

    Amrit Hospital, Chennai has a good track record in bladeless Lasik surgery at chennai . The hospital has a good team of doctors. The hospital has a patient centric approach and friendly environment and offers best bladeless Lasik Surgery in Tamil Nadu

    Regain Your Vision With Cataract Surgery

    Cataract is the clouding of ones eye's natural lens, which lies behind the iris and the pupil. Cataracts are the most common cause of vision loss in people over the age of 40 and are the most common cause of blindness in the world.

    Symptoms and signs of cataract:
    In the beginning cataract has little effect on the vision. Later on the vision is blurred, similar to looking through a cloudy piece of glass. A cataract may make light from the sun or a lamp too bright or glaring. It may also come to notice that the oncoming headlights during the night causes more glare than before. Colors may not appear as bright as they once did.

    Causes of cataract
    The lens inside the eye works much like a camera lens, focusing light onto the retina for clear vision. These lens help us to see things clearly and also adjust the eye's focus.

    The lens is mainly made of protein and water . The protein is arranged in a precise way that keeps the lens clear and let’s light passes through it. But as we age, some of the protein may combine together and start to cloud a small area of the lens. A cataract may grow larger and cloud more on the lens over time, making it harder to see.

    How is cataract treated?

    Cataract surgery is very successful in restoring vision. During surgery, the surgeon will remove the clouded lens and in most cases replace it with a clear, plastic IOL (Intraocular lenses). In addition to this, Bladeless cataract surgery is also used to treat cataract. It is a Laser assisted cataract surgery, which is based on computer guided technology that delivers a higher level of accuracy to the cataract surgery.

    Amrit Hospital, Chennai, been established with the intention to provide quality eye care at an affordable price. Their main focus is the treatment and care of patients from all levels.
