Yes, an optometrist can diagnose glaucoma by performing a dilated eye exam. It is important to get annual eye exams as glaucoma is usually a silent disease. If you are experiencing vision issues, it is even more important to visit an optometrist as soon as possible, as seeking an immediate diagnosis is essential to receiving proper treatment.

An optometrist can detect signs of potential vision deterioration caused by this eye disease. With early detection, your optometrist can provide the specialized care needed to help retain your vision as much as possible.

Read on to learn more about how an optometrist diagnoses and treats glaucoma.

What Is Glaucoma?

Glaucoma is a serious eye disease affecting hundreds of thousands of people in Canada.  It is a condition characterized by damage to the optic nerve, which is the vital link between the eyes and the brain. Damage to these delicate fibres leads to blind spot formation in our vision. 

Most but not all forms of glaucoma are associated with a high fluid pressure (intraocular pressure or IOP) within the eye. Left untreated, glaucoma can lead to severe vision loss and even blindness.  

Primary open-angle glaucoma is the most common form, but many other types of glaucoma also exist.

Glaucoma Symptoms

Because glaucoma may not exhibit outward symptoms in the early stages, it’s crucial to have regular eye exams to detect potential abnormalities. Glaucoma can cause serious, permanent damage to vision and can develop in one or both eyes.

Individuals with a family history of glaucoma are more likely to be affected. Early detection and treatment can provide individuals with the best chance at maintaining healthy vision, so don’t delay getting your eyes checked!

How Glaucoma Develops 

There are various reasons why glaucoma could occur, from anatomical variation to injuries, inflammation or aging. The varying contributing factors and typical slow progression of the disease often means glaucoma can go undetected for many years before sight loss becomes noticeable.

How Glaucoma Is Treated

Medicated eye drops are typically the first line of defence, which aim to reduce the pressure within the eye and protect the optic nerve from further damage. Different types of prescription eye drops work differently, such as reducing the amount of intraocular fluid produced, or supporting the function of drainage canals.

Similarly, surgery options can target glaucoma through laser or other devices to reduce pressure.

How Can You Protect Yourself from Glaucoma?

There are some preventative measures you can take to support healthy vision and protect your eyes from glaucoma.

  • Maintain a healthy weight 
  • Control your blood pressure
  • Avoid smoking
  • Stay physically active with activities like walking or running

But the most important step to protect your eyes is to ensure routine complete eye health examinations.  This will detect risk factors and diagnose glaucoma as early as possible so that treatment may be started to prevent or slow damage.
