Q: What Are the Symptoms of Glaucoma?

Primary Open-Angle Glaucoma Typically develops slowly with no noticeable vision loss for years until advanced and irreversible damage has been done. This is why regular eye checks and early detection are so crucial. Gradual loss of peripheral vision Angle-Closure Glaucoma Sudden vision loss Severe eye and head pain Hazy or blurry vision Nausea

Question 1

What is Glaucoma & How Does It Develop?

Accepted Answer

Glaucoma is a disease that damages the eye’s optic nerve. It typically happens when fluid builds up in the front of the eye, which increases eye pressure, damaging the optic nerve in the process.
Left untreated, glaucoma will result in progressive and irreversible vision loss.

Question 2

How Many Types of Glaucoma Are There?

Accepted Answer

Primary Open-Angle Glaucoma - The most common type of glaucoma, this happens gradually due to the eye not being able to drain fluid as well as it should. As a result, eye pressure gradually builds and damages the optic nerve.
Angle-Closure Glaucoma - This happens when a person’s iris is very near the drainage angle in their eye, thus blocking the drainage angle. When this happens, eye pressure rises very quickly. This is known as “acute glaucoma”, which is a medical emergency and must be attended to immediately to preserve sight.

Question 5

How is Glaucoma Diagnosed?

Accepted Answer

By checking your eye pressure
By examining your optic nerve
By testing your visual field (especially the periphery)

Question 6

Treatment: How Does Glaucoma Eye Drops Work?

Accepted Answer

They decrease eye pressure by helping the eye drain fluid better and/or decrease the amount of fluid produced by the eye
With glaucoma being a progressive condition requiring long-term care, the patient must be diligent in taking the eye drops daily
Like most medicines, these eye drops may have some side effects. Thus, finding the best suited one with minimal to no side effects for you is crucial.

Question 7

Treatment: How Does Glaucoma Laser Surgery Work?

Accepted Answer

Also known as Selective Laser Trabeculoplasty (SLT), this can be used as a primary (alternative) or complementary form of treatment to eye drops
Main Advantage: If this method alone can reduce eye pressure to an appropriate level, then there will be no need to take daily eye drops just yet, which may come with side effects
Main Disadvantage: The effect of laser treatment is usually temporary, thus most patients will likely need to go on daily medications eventually after a few years

Question 8

Treatment: How Does Glaucoma Eye Surgery Work?

Accepted Answer

A last resort if all else fails, eye surgery for glaucoma is minimally invasive in nature and its main purpose is to drain the extra fluid out of the eye
Can be done through placing a tiny tube inside the eye to facilitate drainage or by making a tiny cut in the eye’s drainage tubes to ease fluid buildup
