Are You at Risk For Glaucoma?
Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve. It is the second leading cause of blindness. Early detection, through regular and complete eye exams, is the key to protecting your vision.
Don't let Glaucoma darken your life. Read moreThis year World Glaucoma Week (WGW) is being celebrated from March 11th To March 17th 2012.

In most forms of glaucoma, what damages the optic nerve?
- A.
Eyestrain from reading in a darkened room
- B.
Too much pressure on the optic nerve
- C.
Too little pressure on the optic nerve
- D.
Not wearing prescription glasses
Correct Answer
B. Too much pressure on the optic nerveExplanation
In most forms of glaucoma, the optic nerve is damaged due to excessive pressure. This pressure can build up in the eye, leading to compression and damage to the optic nerve. This damage can result in vision loss and other symptoms associated with glaucoma.Rate this question:

If your eye pressure is normal, you
- A.
May not have glaucoma
- B.
May have glaucoma
- C.
“A” or “B”
- D.
Don't need eyeglasses
Correct Answer
C. “A” or “B”Explanation
If your eye pressure is normal, it means that the pressure inside your eyes is within the normal range. This suggests that you may not have glaucoma, as high eye pressure is a common indicator of the condition. However, it is important to note that normal eye pressure does not completely rule out the possibility of glaucoma, as there are other factors and tests that need to be considered for a definitive diagnosis. Therefore, the correct answer could be either "A" or "B" depending on further examination and evaluation.Rate this question:

What are the symptoms of angle-closure glaucoma?
- A.
Pain
- B.
A red eye
- C.
Blurred vision
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The correct answer is "All of the above." Angle-closure glaucoma is a condition where the drainage angle of the eye becomes blocked, leading to increased eye pressure. This can cause various symptoms, including pain, a red eye, and blurred vision. Therefore, all of the mentioned symptoms are associated with angle-closure glaucoma.Rate this question:

Which of these groups is at risk for developing open-angle glaucoma?
- A.
People older than 60
- B.
Myopia
- C.
People with a family history of glaucoma
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
All of the above groups are at risk for developing open-angle glaucoma. People older than 60 are more likely to develop glaucoma due to the natural aging process. Myopia, or nearsightedness, is also a risk factor for glaucoma. People with a family history of glaucoma have a higher chance of developing the condition as it can be hereditary. Therefore, all three groups mentioned are at risk for developing open-angle glaucoma.Rate this question:

- 5.
Which of these is an early symptom of open-angle glaucoma?
- A.
Blurry vision
- B.
Tearing eyes
- C.
No symptoms
- D.
Burning eyes
Correct Answer
C. No symptomsExplanation
Open-angle glaucoma is a condition that often develops slowly and gradually, leading to irreversible vision loss if left untreated. In the early stages of this disease, there are typically no noticeable symptoms. This is why regular eye exams are crucial, as they can detect glaucoma before any symptoms appear. By the time symptoms like blurry vision or burning eyes occur, the disease may have already progressed significantly. Therefore, the absence of symptoms is an early indication of open-angle glaucoma.Rate this question:

How is glaucoma detected?
- A.
Dilated eye exam
- B.
Visual field test
- C.
Tonometry test
- D.
Pachymetry test
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
Glaucoma can be detected through various tests, including a dilated eye exam, visual field test, tonometry test, and pachymetry test. A dilated eye exam allows the doctor to examine the optic nerve for signs of damage. A visual field test measures the peripheral vision to detect any abnormalities. Tonometry test measures the pressure inside the eye, which is often elevated in glaucoma. Pachymetry test measures the thickness of the cornea, as thin corneas are a risk factor for glaucoma. Therefore, all of these tests are used to detect glaucoma.Rate this question:

How is glaucoma treated?
- A.
Laser trabeculoplasty
- B.
Medication
- C.
Surgery
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Glaucoma can be treated through various methods, including laser trabeculoplasty, medication, and surgery. Laser trabeculoplasty is a procedure that uses a laser to improve the drainage of fluid from the eye, reducing intraocular pressure. Medication, such as eye drops or oral medications, can be prescribed to lower eye pressure and prevent further damage to the optic nerve. In some cases, surgery may be necessary to create a new drainage channel or to improve the existing one. Therefore, all of the options mentioned - laser trabeculoplasty, medication, and surgery - can be used to treat glaucoma.Rate this question:

How can you reduce the damage from glaucoma?
- A.
Visit an eye doctor regularly
- B.
Take your glaucoma medications
- C.
Get family members checked for glaucoma
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Regular visits to an eye doctor are important for early detection and treatment of glaucoma, as they can monitor the progression of the disease and adjust the treatment plan accordingly. Taking prescribed glaucoma medications as directed by the doctor can help in controlling the intraocular pressure and reducing the damage caused by glaucoma. Additionally, getting family members checked for glaucoma is crucial as it is a hereditary disease, and early detection in relatives can lead to early intervention and prevention of further damage. Therefore, all of the above options can help in reducing the damage from glaucoma.Rate this question:
-
- 9.
You always get glaucoma if you have increased eye pressure
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because not everyone with increased eye pressure will develop glaucoma. While high eye pressure is a risk factor for glaucoma, it does not guarantee that a person will develop the condition. Glaucoma is a complex disease that involves various factors, including genetics, age, and other medical conditions. Some individuals may have increased eye pressure but never develop glaucoma, while others may have normal eye pressure but still develop the condition. Therefore, it is incorrect to assume that increased eye pressure always leads to glaucoma.Rate this question:

- 10.
Most people with open angle glaucoma have no symptoms
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Open angle glaucoma is a type of glaucoma where the drainage angle of the eye is open, but the fluid does not drain properly, leading to increased pressure in the eye. In the early stages, there are usually no noticeable symptoms, which is why it is often referred to as the "silent thief of sight." Without regular eye exams, individuals may not be aware of the condition until it has progressed and caused irreversible damage to their vision. Therefore, it is true that most people with open angle glaucoma have no symptoms.Rate this question:
