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.


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.


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.
