Glaucoma and Its Effects

15 Apr

What is Glaucoma?

Glaucoma is a group of diseases that produces increased pressure within the eye, in most cases. This pressure is caused by a backup of fluid in the eye that causes damage to the optic nerve, over time.

How is Glaucoma caused?

Any disturbance for the flow of the aqueous humor can raise the Intra Ocular Pressure (IOP) of the eye. Unless the pressure at the front of the eye is controlled, it can damage the optic nerve and cause vision loss.

Who is at risk?

Although anyone can get glaucoma, some people are at higher risk than others. They include:

  • Blacks over 40 years of age.
  • Everyone over 60 years of age.
  • People with a family history of glaucoma.

Symptoms

Initially, open-angle glaucoma has no symptoms. Vision stays normal, and there isn’t any pain. As glaucoma remains untreated, people may notice that although they see things clearly in front of them, they miss objects to the side and out of the corner of their eye.

Without treatment, people with glaucoma may find that they suddenly have no peripheral (side) vision. It may seem as though they are looking through a tunnel. Over time, the remaining central distance vision may decrease until there is no vision left.

Vision with glaucoma normal vision.

Types of Glaucoma:

Although open-angle glaucoma is the most common type, some people have other types of this disease.

  • In low-tension or normal-tension glaucoma, optic nerve damage and narrowed peripheral vision occur unexpectedly in people with normal eye pressure.
  • In closed-angle glaucoma, the fluid at the front of the eye cannot reach the angle and leave the eye because the angle gets blocked by part of the iris. People with this type of glaucoma have a sudden increase in pressure. Symptoms include severe pain and nausea as well as redness of the eye and blurred vision. This is a medical emergency. The patient needs immediate treatment to improve the flow of fluid. Without treatment, the eye can become blind in as little as one or two days. Usually, prompt laser surgery can clear the blockage and protect sight.
  • In congenital glaucoma, children are born with defects in the angle of the eye that slow the normal drainage of fluid. Children with this problem usually have obvious symptoms such as cloudy eyes, sensitivity to light, and excessive tearing. Surgery is usually the suggested treatment. If surgery is done promptly, these children usually have an excellent chance of having good vision.
  • Secondary glaucoma can develop as a complication of other medical conditions. They are sometimes associated with eye surgery or advanced cataracts, eye injuries, certain eye tumors, or uveitis (eye inflammation).

One type, known as pigmentary glaucoma, occurs when pigment from the iris flakes off and blocks the meshwork, slowing fluid drainage.

A severe form, called neovascular glaucoma, is linked to diabetes. Also, corticosteroid drugs—used to treat eye inflammations and other diseases—can trigger glaucoma in few people. Treatment is through medicines, laser surgery or conventional surgery.

How is glaucoma detected?

Most people think that they have glaucoma if the pressure in their eye is increased. This is not always true. High pressure puts a person at risk for glaucoma. Whether or not they have glaucoma, depends on the level of pressure that their optic nerve can tolerate without being damaged. Although normal pressure is usually between 12-21 mm Hg, a person might have glaucoma even if the pressure is within this range.

An eye examination is very important, to investigate glaucoma, the following tests are a must:

  • Visual acuity: This vision test measures how well you see at various distances.
  • Visual Field: This test measures your side (peripheral) vision. It helps your eye care professional find out if you have lost any peripheral vision, a sign of glaucoma.
  • Pupil dilation: This examination provides your eye care professional with a better view of the optic nerve to check for signs of damage. Your eyes will be dilated with drops and after examination your near vision may remain blurred for few hours.
  • Tonometry: This standard test determines the fluid pressure or Intra Ocular Pressure (IOP) of the eye.

Treatment of Glaucoma:

Although there is no cure for glaucoma, treatment can often control it. This makes early diagnosis and treatment important. In common practice, medication is recommended for newly diagnosed glaucoma. However, new research findings show that laser surgery is a safe and effective alternative.

Medicine: Medicines – either eye drops or pills – are the most common early treatment for glaucoma. Some cause the eye to make less fluid, whereas others lower pressure by helping fluid drain from the eye.

Laser surgery (also called laser trabeculoplasty): Laser surgery helps fluid drain out of the eye. Although this may be suggested at any time, it is usually done after trying out treatment through medicines. In many cases, glaucoma drugs have to be taken even after laser surgery.

Conventional surgery: The purpose of surgery is to make a new opening for the fluid to leave the eye. This surgery is often done after medicine and laser surgery have failed to control pressure.

Acupuncture for Eyes

17 Jan

Acupuncture has been known and used in Japan, China and India since the Stone Age. It is an ancient healing art that uses fingers to gradually apply pressure to key healing points that stimulate the body’s natural curative abilities. Stimulating these points can actually correct imbalances in the flow of qi or ‘life energy’ through channels (pathways for life energy) known as meridians.

Simply massaging these points helps restore the energy flow and eventually, the normal and healthy functioning of the body. Each part of the body has a corresponding organ. For example, diseases involving the eye are closely related to the malfunctioning of the liver. Below are:

Some of the areas of the body and their corresponding organs:

Lens and pupil belong to the kidney,

Sclera to the lungs,

Arteries and veins to the heart,

Top eyelid to the spleen,

The bottom eyelid to the stomach,

The cornea and iris to the liver.

MAJOR ACUPRESSURE EYE POINTS

B 1 is at the side of the nose next to the inner corner of the eye. B 2 is on the forehead in the depression at the inner end of the eyebrow. These points are helpful for correcting blurred vision, early stage cataracts, conjunctivitis and glaucoma.

The Yuyao point is in a depression in the middle of the eyebrow, good for correcting eye problems associated with worry and mental strain.

Sanjiao is in the depression at the outer end of the eyebrow, good for correcting eye and facial problems.

GB 1 is in the eye socket, next to the outside corner of the eye, good for correcting blurred vision, early stage cataracts, conjunctivitis, dry eyes, headaches, itchy eyes and photophobia.

ST 1 is on the ridge bone of the eye socket, directly below the pupil and a main point for correcting eye problems.

Qiuhou is on the eye socket between ST 1 and GB 1. Eye diseases such as optic neuritis, optic atrophy, pigmentary degeneration of the retina, glaucoma, early stage of cataract, myopia are linked with this area.

Acupressure routine:
Gently massage the points around the eyes for 5 to 10 seconds.

Start with B 1 at the inner corner of the eye and gently massage the point for approximately 5 to 10 seconds.

Then gently massage B 2 and continue massaging each eye acupressure point.

You can massage the points near each eye individually or both of your eyes at the same time.

Repeat this massage as many times as you want to throughout the day.

Keep BREATHING as you massage. Practice long, slow abdominal breathing while massaging the acupressure points.

  • Become familiar with the location of the acupressure eye points.
  • Remember to use gentle pressure with eye acupressure points.
  • Don’t press too hard.
  • Use either the tip of your middle finger or the knuckle of the same finger.

CAUTION: If you are pregnant or unsure of the method, consult a trained acupuncturist before treating yourself. Do not attempt acupressure on an area if it has a scar, burn or an infection.

The Health Eye

31 Dec

We are constantly bombarded with the latest diet fads and crazes which promise to help us lose weight. Not surprisingly, there is no clear winner in the race to be the ‘best’ diet plan – no single diet will work for everyone – but most people accept that providing your body with foods rich in healthy nutrients is a good starting point.

What many people fail to consider is that your eyes are no exception to this – nutrition is an essential part of maintaining good vision into later life.

The Eye-Health Diet

A diet high in fat and cholesterol can lead to a build-up of fatty deposits in the blood vessels under the macula. This increases the risk of age-related macular degeneration (AMD). So researchers advise that people should try to eat five portions of fruit and vegetables a day, maintain a low-fat diet and eat foods rich in antioxidants

The two nutritional pigments lutein and zeaxanthin can be found naturally in a number of food sources. For example, lutein can be found in yellow peppers, mango, bilberries and green leafy vegetables such as kale, spinach, chard and broccoli. Zeaxanthin can be found in orange sweet peppers, broccoli, corn, lettuce, spinach, tangerines, oranges and eggs.

Despite nutritional advice being available, awareness of the link between diet and eye health is poor.

Nutrition of the Eye

The main nutritional components of the eye are pigments known as carotenoids. There are over 600 known carotenoids in nature. In the human eye, just three of these nutritional pigments – lutein, zeaxanthin and meso-zeaxanthin – form a concentrated ‘yellow spot’ in the macular, known as the macular pigment.

This pigment has two main functions: it acts as an antioxidant and it filters light.

As short wavelength (blue) light passes through the retina to the photoreceptors and pigmented epithelial cells, reactive oxygen species are generated. The conversion of the light energy into a nerve impulse by the photoreceptors generates free radicals – unstable molecules which damage a variety of tissues – resulting in many of the diseases and conditions associated with ageing. Antioxidants in the eye are able to quench these free radicals, thereby protecting the eye from oxidative damage. Lutein, zeaxanthin and particularly meso-zeaxanthin are very effective antioxidants.

Blue light, because of its relatively high photon energy, more readily damages the retina than yellow or red light, which is less energetic. The macular pigment acts as a filter, particularly to blue light, and therefore protects against this damaging effect.

These two functions are extremely important as they help protect against worsening of diseases of eye, such as AMD.

Superfoods for the Eye

These foods should be recommended to patients for the maintenance of good eye health:

  • Nuts and berries
  • Spinach, kale and green leafy vegetables
  • Blueberries and grapes
  • Eggs
  • Cold water fish
  • Papaya
  • Garlic, onions and capers
  • Soy
  • Virgin olive oil

Lawrence & Mayo, The Regal Opticians

18 Jul

There are companies that have a history; and then there are companies that are historic. In the case of Lawrence & Mayo, the latter is a fitting introduction. Established in 1877, Lawrence & Mayo has carved a niche for itself as India’s leading manufacturing and dispensing optician with diversification in scientific and industrial instrumentation. To say that anyone from our grandparents’ generation, to us and our children today have Lawrence & Mayo in common, is a fact. But it’s a fact that’s a glorious reminder of the tenacity, history and the shining present of the company.  

Lawrence and Mayo traces its roots to two London based Jewish families, that of Lawrence and Mayo. The two families set up operations all over the world, including London, Cairo, Spain, Portugal, Indian subcontinent, Colombo, Rangoon and Singapore. High-grade Opticians and makers of best quality Survey, Scientific and Meteorological instruments; Lawrence & Mayo has made a rich contribution in India too. 

It was way back in 1877, when Lawrence & Mayo made their foray in India with a showroom in Calcutta. By 1925, Lawrence & Mayo, headquartered in New Oxford Street, London, boasted of showrooms in Alexandria, Bombay, Cairo, Calcutta (Kolkata), Delhi, Lucknow, Madras (Chennai), Rangoon and Simla. By the 117th year of their operations, the company had established its firm presence in 11 cities with 17 showrooms and millions of satisfied customers. 

Crucially Lawrence & Mayo’s Instruments & Scientific Instrumentation Division also has a major impact on the industry. This division is an integral part of the L&M house since its inception in 1877. The division is at the forefront in providing state-of-the-art Scientific and Engineering instruments and has tie-ups with international companies for their wide range of instruments. It provides Geometric and Engineering Instruments, general Laboratory Instruments and accessories. The company supplies these instruments to Railways, Collieries, Oil Industry, Universities, Quality Control and Research Laboratories. L&M is one of the biggest importers of these instruments and understands the market well.

But the company’s tremendous history also adds to the large contributions and innovations that they have introduced over the many decades of their existence. Aside from being the opticians of choice to the British empire, Lawrence & Mayo has served India in a dedicated manner. With regular firsts to its credit, such as the introduction of contact-lenses in the Indian market in 1975, Lawrence & Mayo earned the distinction of being the most experienced and trustworthy quality opticians. 

It was they who introduced Computerized Eye-Testing way back in 1988. And with the strategic & rapid expansion of their network, with key branches such as the one in Coimbatore added in 2001, Lawrence & Mayo continues to be at the very forefront of ophthalmology in India. 

Today Lawrence & Mayo stands tall and is well-equipped to meet the needs of the rapidly growing market for eye care and precision instruments. Having specialized in the fields of engineering, scientific and vacuum instruments, the company’s core success lies in its professionalism. And their main aim remains, to serve the people of India.

Age & Eyes, What’s Common?

8 Jul

Last month, I was visiting my grandparents in Kolkata, and for the first time in so many years, my grandfather asked me to read him the morning papers. For someone who’s been very religious with his morning newspaper, it was sad for me to see him rely on someone else reading it out to him. Why? Because his eyes had become too weak. 

You see, my grandfather is a healthy man, and his eyes giving way like this got me thinking, and I decided to find out if age and eyes are connected. Sure enough, it turned out that age, indeed, was the cause of his weak eyesight!

 

The ageing process brings about changes that have a direct bearing on the eyesight. Not only do the eyes suffer directly, the increasing fragility, and susceptibility to other ailments, of the body are detriment to the eyes as well. Some of the more common signs of age-related eye problems that I found are: 

Floaters: These are small particles that float through your line of vision, and can be early signs of retinal detachment. One is, therefore, best advised to visit a doctor.

Excess Tears: No, not just because the elderly are more emotional! This is due to over-sensitivity to light, wind, or changes in temperature. 

Eyelid Irritations: Redness and swollen eyelids, itching, tearing, and crusting of eyelashes. 

Aside from these, I found that the loss of clear sight, which is what prevented my grandfather from reading his papers, was due to old eyes not having the power to focus – a condition medically referred to as Presbyopia.

 

Of course, I took my grandfather to an ophthalmologist, and and we got him prescription reading glasses, which have since allowed him to read his newspaper. But the sad truth remains that age and eyes are inextricably linked, and unfortunately, the health of the latter deteriorates with the gain of the former. So, when are you having an eye check-up of the elders of your family?
