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.
• Congenital: A rare, inherited form present at birth.

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
