Dr Echendu Damian, an Optometrist, says more than 11.2 million people will lose their ability to see properly by 2020 due to the effect of glaucoma worldwide.

Damian, who is the Chairman of the Nigerian Optometric Association, FCT Chapter, said this in Abuja on Monday on the sidelines of a walk organised by the Ophthalmological Society of Nigeria, as part of activities to mark the World Glaucoma Week.

According to him, already glaucoma had rendered 4.5 million blind gblobally.

He said that the walk was organised to create awareness on the menace of glaucoma and advised the public to ensure that it examined its eyes at least once a year.

“Glaucoma is the silent thief of sight. It’s a group of diseases that lead to damage to the optic nerve, the nerve that sends information to the brain, for one to see.

“And it is estimated that globally, about 4.5 million people have been blind due to glaucoma; and it is also projected that by the year 2020 about 11. 2 million will lose their sight due to glaucoma.

“So, what we are doing today is to enlighten the public on this scourge and to let them know that it’s very important for them to go to an eye clinic and have their eyes examined at least once every year.

“Why we are saying this is because glaucoma is a condition that does not come with any sign or symptom.

“One can wake up one day and find out that he or she is not seeing. And by the time he or she gets to the hospital you find out that its glaucoma that has caused it.’’

The chairman said though glaucoma could not be treated, its progression could be slowed down to prevent blindness if diagnosed early.

“We are having free screening in all clinics and all the general hospitals in the FCT for glaucoma.

“So, from today (Monday) till Friday, members of the public have been invited to avail themselves of the opportunity to go to the eye clinics in town, go to the general hospitals in Kubwa, in Asokoro, in Wuse, in Maitama, in the State House Medical Centre, in Gwagwalada Specialist Hospital, in other private eye clinics in town and have their eyes screened for glaucoma for free.”

Damian, who said that there was no known cause of glaucoma, explained that some of the conditions that could encourage its emergence were increase in eye pressure, short sightedness and family history.

He said that glaucoma was more common in black people and people above the age of 40 years were also at risk.

“If you are above 40 years of age, it’s also expedient that you will have your eyes checked because it’s also common with advancing age.’’

NAN reports that members of the all the ophthalmological societies in the FCT participated in the walk.

The walk commenced from Berger through Wuse market carrying placards and distributing flyers, after which a health talk on glaucoma was given.

Some of the placards read: “190,000 Nigerians are diagnosed with glaucoma yearly’’; “Half the people with glaucoma do not know they have it’’; and “If you change your glasses frequently, get screened for glaucoma’’.

GLAUCOMA
Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often associated with a buildup of pressure inside the eye. Glaucoma tends to be inherited and may not show up until later in life.
The increased pressure, called intraocular pressure, can damage the optic nerve, which transmits images to the brain. If damage to the optic nerve from high eye pressure continues, glaucoma will cause permanent loss of vision. Without treatment, glaucoma can cause total permanent blindness within a few years.
Because most people with glaucoma have no early symptoms or pain from this increased pressure, it is important to see your eye doctor regularly so that glaucoma can be diagnosed and treated before long-term visual loss occurs.
If you are over the age of 40 and if you have a family history of glaucoma, you should have a complete eye exam with an eye doctor every one to two years. If you have health problems such as diabetes or a family history of glaucoma or are at risk for other eye diseases, you may need to visit your eye doctor more frequently.

Why Does Pressure Rise in the Eye to Cause Glaucoma?

Glaucoma usually occurs when pressure in your eye increases. This can happen when eye fluid isn't circulating normally in the front part of the eye.
Normally, this fluid, called aqueous humor, flows out of the eye through a mesh-like channel. If this channel becomes blocked, fluid builds up, causing glaucoma. The direct cause of this blockage is unknown, but doctors do know that it can be inherited, meaning it is passed from parents to children.
Less common causes of glaucoma include a blunt or chemical injury to the eye, severe eye infection, blockage of blood vessels in the eye, inflammatory conditions of the eye, and occasionally eye surgery to correct another condition. Glaucoma usually occurs in both eyes, but it may involve each eye to a different extent.

What Are the Types of Glaucoma?

There are two main types of glaucoma:
1. Open-angle glaucoma. Also called wide-angle glaucoma, this is the most common type of glaucoma. The structures of the eye appear normal, but fluid in the eye does not flow properly through the drain of the eye, called the trabecular meshwork.
2. Angle-closure glaucoma. Also called acute or chronic angle-closure or narrow-angle glaucoma, this type of glaucoma is less common but can cause a sudden buildup of pressure in the eye. Drainage may be poor because the angle between the iris and the cornea (where a drainage channel for the eye is located) is too narrow

Q. Is there any way to prevent glaucoma?

There is nothing that will prevent glaucoma, but you can slow down its development with early treatment. Therefore, it is very important that you have regular eye exams. Your doctor will perform a series of painless tests -- eye pressure measurements, dilated eye exams, and sometimes visual field testing -- to check for any changes in your eye or in your vision. With early detection, glaucoma can often be controlled with medications, either eye drops or pills. If your glaucoma doesn't respond to medication, your doctor may also recommend surgery. Remember, about half of people with glaucoma don't know they have it, and doctors cannot reverse damage from glaucoma. Vision lost is irreversible, you can't get your vision back once it is lost. Your best protection is to get regular eye exams, every couple of years if you are over 40 or on a schedule recommended by your doctor.
It's important for adults to have eye exams on a regular basis to check for problems. Regular eye exams are critical for detecting: Glaucoma Age-related macular degeneration (AMD) Cataracts Diabetic retinopathy But everyone needs regular eye exams. This is particularly important if you have risk factors or a family history of eye problems. Children need their vision checked at 6 months, 3 years, and before first grade. These exams should be done during preventative pediatrician visits...

Q. If I have glaucoma, will I become blind?

The chances are good that you will not go blind if you take your medication correctly and regularly and follow up with your doctor. Treatment significantly slows the damage that occurs to the optic nerve because of the high pressure in the eye. In fact, if you take your eye drops on schedule each day, you'll probably keep your eyesight until the day you die of old age!

Q. If my parent has glaucoma, will I get it?

Not necessarily, but it does increase your risk. Other factors that may increase your risk are:
• Being over age 50
• Being over age 40 and African-American
• Having a family history of glaucoma
• Having a history of serious eye injury
• Taking steroid medications
• Having diabetes
• Being nearsighted
• Having high blood pressure
People with these risk factors should have their eyes examined on a regular basis to look for the disease.

Q. Are there effective treatments for glaucoma?

Yes. There are many different types of medications (in eye drops or pills) that are used to treat glaucoma. Typically, the doctor will start you on an eye drop formula. The medications work two ways: Some decrease how much fluid is produced in the eye; others help the fluid flow out better. Many people can preserve their vision if they take their medications as scheduled and visit their doctor regularly. Note: Medications for glaucoma -- even eye drops -- can affect the entire body, so you should alert all of your doctors that you are taking them.

In some people, however, drugs alone do not control the eye pressure, and surgery is needed. One type of surgery called laser trabeculoplasty uses a laser to improve the flow of fluids out of the eye. This can be done in your doctor's office. There are also several conventional surgeries -- the most common is called trabeculectomy -- in which your doctor creates a new drainage path in the eye under the eyelid. This surgery must be done in an operating room. After both of these procedures, people may still have to take eye drops to further lower the eye pressure.
