Glaucoma: The Silent Thief Of Sight

The eye as a sense organ enable us to see. The gift of sight is truly a wonderful gift! With so many diseases afflicting mankind, we can do but a little to completely eradicate eye diseases. One of such eye diseases is glaucoma. Glaucoma is a disorder of the eye that causes damage to the optic nerve as a result from pressure rise (intraocular pressure) in the eye. Normally, the eye fluid (aqueous humour) flows out of the eye through a strainerlike structure called the trabecular meshwork. If this meshwork becomes blocked, pressure inside the eyes increases and lead to nerve damage. The optic nerve transmit images from the retina to the brain for us to see. When the optic nerve is damage, it often lead to glaucoma or reduced vision. Worldwide, millions of people are affected by glaucoma, making it the second-leading cause of blindness after cataracts.

Who is at risk?
Generally everyone is at risk but your risk of developing glaucoma increases if
*. You are over the age of 40
*. You are of African descent
*. You have family history of glaucoma
*. You are nearsighted
*. You are taking certain medications containing cortisone/steroid
*. You have suffered from eye injury before
*. You have diabetes

Other possible causes of glaucoma are eye injuries, cataracts, eye tumours, eye infection, previous corrective surgery on the eyes.

There are two main types of glaucoma; open-angle and close-angle (angle-closure).

Open-angle glaucoma occur slowly without noticeable signs that you are losing vision untill the condition worsen to an advanced stage. This is why glaucoma is called the silent "thief of sight". To avoid the dire consequence, you should always go for eye checkup every year especially if you are in the risk group.

In the closed-angle glaucoma there is a sudden pressure increase in the eyes and is often painful accompanied with blurred vision and vomiting. If treatment is delayed loss of sight can happen so quickly. Therefore, it is beneficial to seek immediate medical attention once you have these symptoms.

High eye pressure in most cases doesn't mean glaucoma. Individual eye pressure varies. However, glaucoma doesn't give any early sign and symptoms, and without warning causes damage to the optic nerve. Hence it is important to see your ophthalmologist so that proper diagnosis can be done and treatment commence before it causes permanent blindness.


Eye drops
There are special eye drops made available for the treatment of glaucoma. The purpose of this eye drop is to inhibit the production of fluid in the front of the eye or to drain the fluid.

Laser surgery
This is done to create open tiny holes in the front of the eyes to increase the outflow of fluid from the eyes.

Operative surgery
This type of surgery involve creating new channels to allow the drainage of aqueous fluid to leave the eyes therefore lowering the eye pressure.

If you are have been diagnosed of glaucoma, your doctor is in the best position to decide which treatment is right for you.

The eye is part of your health so we should take care not to cause harm to it. Avoid direct bright light from entering the eyes. Do not read with dim light. Do not used medicated glass unless recommended by your physician. Avoid particles from entering into the eyes. And if you feel any discomfort in the eye seek medical attention.


  1. I am familiar with this. My father had cataracts. He also had bad arthritis, which the doctor at the time prescribed heavy doses of steroids (which was common treatment in the early 1970’). This in turn caused him to have glaucoma. The combination of both eye deceases robbed him of his sight.
