Question 1

How common is glaucoma disease?

Accepted Answer

Glaucoma is a common eye disease that leads to the damage of the optic nerve. This damage to the optic nerve, which transmits information from the eyes to the brain, results in vision loss. If not treated properly, visual loss may be temporary or permanent. A change in the eye’s internal fluid pressure, also known as intraocular pressure (IOP), is the most common cause of Glaucoma.

Glaucoma affects around 70 million individuals globally. In 2020, glaucoma disease will affect over 80 million individuals worldwide, with the number anticipated to rise to over 111 million by 2040. Glaucoma is the main cause of irreversible blindness, accounting for 12.3% of all blindness worldwide.

Question 2

What is the difference between an open angle and closed angle glaucoma?

Accepted Answer

Below we have given an insight into both these two types of glaucoma:

Open angle glaucoma: The most prevalent type of glaucoma is open-angle glaucoma. It has no symptoms at first; however, side (peripheral) vision is lost at some time, and without treatment, a person can become completely blind.
Closed angle glaucoma: Angle-closure glaucoma, also known as closed angle glaucoma, is a less prevalent kind of glaucoma. It happens when the drainage system in the eye gets fully obstructed, causing the pressure inside the eye to rapidly rise.

Question 3

Can hereditary be one of the glaucoma causes?

Accepted Answer

Glaucoma can be inherited in some cases, and many experts around the world are researching genes and their effects on the disease. Glaucoma is not always hereditary, and the circumstances that lead to the beginning of the illness are yet to be fully understood.

Question 4

What is considered as normal intraocular pressure?

Accepted Answer

The measurement of eye pressure is in millimetres of mercury (mm Hg). The typical range for eye pressure is 12-22 mm Hg, while pressures more than 22 mm Hg are considered abnormal. Glaucoma is not caused by high eye pressure alone. It is, nonetheless, a considerable risk factor. Individuals with high eye pressure should get comprehensive eye exams by an eye care specialist on a regular basis to screen for signs of glaucoma.

Question 5

Is there a glaucoma cure?

Accepted Answer

Unfortunately, there is no glaucoma cure, and the vision loss resulted due to it is irreversible. If someone suffers from open-angle glaucoma, it has to be monitored for the rest of their life.

However, it is possible to slow down or stop additional vision loss using the medication, laser treatment, and surgery. The most important thing to remember here is that the first step in preserving your vision is to get a diagnosis. So, never ignore it if you experience any discomfort in your vision.

Question 6

What's the difference between glaucoma and ocular hypertension?

Accepted Answer

When the classic optic nerve and vision alterations occur, glaucoma disease is diagnosed, usually with raised eye pressure but rarely with normal pressure. Ocular hypertension occurs when the intraocular pressure is higher than usual, but the person does not display indications of glaucoma.

Question 7

What does 'tunnel vision' mean?

Accepted Answer

If not treated adequately in the early stages of glaucoma disease, it can severely affect the peripheral vision, leading to a condition known as ‘tunnel vision. Tunnel vision eliminates your ‘side vision,’ limiting your field of view to images in your central vision or straight ahead.

Question 8

How does glaucoma disease get diagnosed?

Accepted Answer

If you feel that you are experiencing any glaucoma symptoms, it can be detected during a full dilated eye examination. The examination is straightforward and painless: your doctor will dilate (widen) your pupil with eye drops before checking your eyes for glaucoma and other eye issues.

A visual field test is included in the exam to examine your side vision. People with a family history of glaucoma should have their eye pressure and optic nerves tested frequently since they are at a higher risk of developing the condition.
