Glaucoma
Glaucoma: The Silent Thief of Sight
Glaucoma is a progressive eye disease that can cause permanent vision loss if left untreated. Often developing without symptoms, the disease can damage the optic nerve, leading to blind spots and, eventually, total blindness if not diagnosed early. At Adelaide City Optometrist, we provide comprehensive screening, diagnosis, and management to help safeguard your vision.
What is Glaucoma?
Glaucoma refers to a group of eye conditions that increase intra-ocular pressure (IOP), damaging the optic nerve. There are different types of glaucoma, including:
Primary Open-Angle (POAG)
The most common form, developing slowly with no early warning signs.
Angle-Closure
A sudden, severe increase in eye pressure requiring immediate treatment.
Normal-Tension
Occurs even when eye pressure is normal, affecting optic nerve function.
Secondary
Cause by other conditions such as diabetes, cataracts, or trauma.
Symptoms of Glaucoma
Most people with early-stage experience no symptoms. However, as the disease progresses, warning signs may include:
- Blurred or hazy vision
- Loss of peripheral (side) vision
- Eye pain or pressure
- Seeing halos around lights
- Headaches and nausea (in acute cases)
Early Detection & Screening
At Adelaide City Optometrist, we use state-of-the-art technology to detect before symptoms appear. Our screening includes:
- Tonometry: Measures intra-ocular pressure
- Optical Coherence Tomography (OCT): Scans the optic nerve for damage
- Visual Field Testing: Checks for peripheral vision loss
- Gonioscopy: Examines the drainage angle of
- Retinal Imaging: Captures high-resolution images of the optic nerve

Treatment & Management
While there is no cure, early intervention can slow its progression. Treatment options include:
1. Prescription Eye Drops
Lowering intra-ocular pressure is the first line of defense. Medications such as prostaglandins, beta-blockers, and carbonic anhydrase inhibitors help reduce eye pressure.
2. Laser Therapy (SLT & ALT)
Selective laser Trabeculoplasty (SLT) and Argon Laser Trabeculoplasty (ALT) improve fluid drainage to lower eye pressure.
3. Surgery
For advanced cases, procedures like trabeculectomy, drainage implants, or minimally invasive surgery (MIGS) can be effective in controlling eye pressure.
Who Is at Risk?
Certain groups have a higher risk of developing the disease, including:
- Individuals over 40
- Family history
- People with diabetes, hypertension, or migraines
- African, Asian, or Hispanic descent
- High myopia (near-sightedness)
- Prolonged use of steroid medications

Frequently Asked Questions (FAQ)
What is glaucoma?
Glaucoma is a group of eye diseases that damage the optic nerve, often due to increased intra-ocular pressure. If left untreated, it can lead to vision loss or blindness.
What are the symptoms of glaucoma?
In its early stages, the disease may not cause noticeable symptoms. As it progresses, symptoms can include:
- Blurred vision
- Loss of peripheral (side) vision
- Eye pain or pressure
- Seeing halos around lights
- Sudden vision loss (in acute cases)
Who is at risk for developing glaucoma?
Anyone can develop the disease, but the risk is higher for:
- Individuals over 40
- Those with a family history
- People with high eye pressure (intra-ocular pressure)
- Diabetics and those with high blood pressure
- People of African, Asian, or Hispanic descent
How is glaucoma diagnosed?
It is diagnosed through a comprehensive eye test, which may include:
- Measuring eye pressure (tonometry)
- Checking the optic nerve (ophthalmoscopy)
- Testing peripheral vision (visual field test)
- Measuring corneal thickness (pachymetry)
What are the treatment options for glaucoma?
Glaucoma treatment aims to lower eye pressure and prevent further damage. Common treatments include:
- Prescription eye drops
- Laser therapy (such as SLT or ALT)
- Surgery
Can glaucoma be cured?
There is currently no cure, but early detection and treatment can help slow its progression and preserve vision.
How often should I get my eyes checked for glaucoma?
Regular eye tests are crucial, especially if you are at risk. It is recommended to have an eye exam:
- Every 2 years for adults under 40 (unless recommended more frequently by your optometrist)
- Annually for individuals over 40 or at higher risk
