Glaucoma – a call to have your eyes checked

As we raise awareness of Glaucoma this week (it should continue all year), the impor­tance of community education to pre­vent vision loss, regular eye care and early detection of this silent disease is key. The theme “SEE THE FUTURE CLEARLY” puts the whole process into perspective.

What will you do if after years of enjoying the beauty of the world through your eyes, you wake up one day and realize your eyes are failing or have failed you? It could be a ma­jor life-changing event. You may even run the risk of causing accidents. Imagine what one goes through during the DUM phase of DUMSOR.

Now imagine life perpetually in DUM. All this could be prevented if you make time to care for your eyes: check your eye pressure and have your sight checked as well.

Glaucoma is a group of eye con­ditions that damage the optic nerve (nerve of the eye) leading to loss of vision. It is most often but not always associated with an increase in eye pressure.

In Ghana, glaucoma is a leading cause of blindness second only to cataract. Ghana appears to have many challenges with “vision” (note the pun) as we have been identified as the country with the second (some data quote third) highest prevalence rate of glaucoma.

Glaucoma is sometimes referred to as the “silent thief of sight” be­cause it can damage your vision so gradually that you may not notice any loss of vision until the disease is at an advanced stage. The most common type of glaucoma, primary open-angle glaucoma has no no­ticeable signs or symptoms except gradual vision loss. As always, the key is to be diagnosed early and managed since this can prevent or minimize damage to the optic nerve. Early diagnosis is only possible if we have regular check-ups. I checked my eye-pressures six months ago, what about you?

Isolating the risk factors

1. Age – Anyone can get glauco­ma, but it most often occurs in those above forty years.

2. Ethnicity – Africans and African Americans are at an increased risk compared to Caucasians. In high-risk groups it may be necessary to have your eyes checked even in your 20s.

3. Family History/ Genetics – You are at an increased risk if a member of your family has glaucoma.

4. Medical Conditions – Diabetics and people with hypothyroidism are also prone

5. Nearsighted/shortsighted – For this group of people, objects in the distance appear fuzzy without correc­tive lenses.

6. Prolonged Steroid use – espe­cially if used as eye drops, increases our risk for glaucoma.

7. Other Eye conditions – Severe eye injury, some of which may even cause the eye lens to dislocate. Retinal detachment, eye tumours and some eye infections may also pre­dispose us. Some eye surgeries may occasionally trigger glaucoma.

Recognising the warning signs

It is important to drum home the point that just as in high blood pres­sure, there may be no warning signs. As stated above, the commonest form of glaucoma will hardly warn you. In some forms of glaucoma, however, we may experience the following:

1. Gradual loss of peripheral (side) vision leading to tunnel vision where one is able to see only objects direct­ly in front of him/her

2. Redness of the eye

3. Blurred vision

4. Halos around lights

5. Severe eye pain is sometimes associated with nausea and vomiting

6. Sudden onset of poor vision especially in low light

Overview of tests available

1. Measuring eye pressure. This is a simple painless procedure. It is often the first line for screening for people with glaucoma.

2. Visual Field Test – your doc­tor will use this test to determine whether glaucoma has affected your peripheral vision

3. Several other tests are avail­able and include testing for optic nerve damage and measuring corneal thickness.

Treatment options

There is NO CURE for glaucoma, but it can be successfully managed. Our options include eye drops, oral medication or surgery, which reduce pressure in the eye to a level that is unlikely to cause further optic nerve damage.

You may not be able to prevent glaucoma, but you can avoid its com­plications if diagnosed and its man­agement started early. Talk to your healthcare professional and have eye examinations when necessary.

This is the only way to ensure that you can “…see clearly now the rain is gone. I can see all obstacles in my way” and you will enjoy this great vision for years to come.

Glaucoma is “a silent thief of sight.” This is another reminder that NOT ALL SILENCE IS GOLDEN! Get checked.

AS ALWAYS LAUGH OFTEN, ENSURE HYGIENE, WALK AND PRAY EVERYDAY AND REMEMBER IT’S A PRICELESS GIFT TO KNOW YOUR NUMBERS (blood sugar, blood pres­sure, blood cholesterol, BMI)
