Glaucoma: A Silent Threat to Vision – What You Need to Know

Glaucoma is one of the leading causes of irreversible blindness worldwide, yet many people are unaware they have it until significant vision loss has already occurred. Often called the “silent thief of sight,” glaucoma typically develops slowly and without noticeable symptoms in its early stages.

At Rose Optometry, we are committed to early detection and ongoing management of glaucoma for patients across Berry, Nowra, Shoalhaven Heads, Bomaderry, Vincentia, and the wider Shoalhaven region.

What Is Glaucoma?

Glaucoma is a group of eye conditions that damage the optic nerve, which is essential for clear vision. This damage is often associated with increased pressure inside the eye (intraocular pressure), although glaucoma can occur even when eye pressure is within normal ranges.

If left untreated, glaucoma can lead to permanent vision loss and blindness.

Types of Glaucoma

The most common types include:

• Primary Open-Angle Glaucoma
  The most common form, developing slowly over time with no early warning signs.

• Angle-Closure Glaucoma
  Less common but more urgent, this can occur suddenly and requires immediate medical attention.

• Normal-Tension Glaucoma
  Optic nerve damage occurs despite normal eye pressure.

• Secondary Glaucoma
  Caused by other conditions such as eye injury, inflammation, or medications.

Symptoms: Why Regular Eye Tests Matter

In its early stages, glaucoma usually has no symptoms. Vision loss typically begins in the peripheral (side) vision and progresses slowly.

By the time noticeable symptoms appear, significant and irreversible damage may already have occurred.

This is why regular comprehensive eye examinations are critical—especially if you are over 40 or have risk factors.

Risk Factors for Glaucoma

You may be at higher risk if you:

• Are over 40 years of age

• Have a family history of glaucoma

• Have high eye pressure

• Are short-sighted (myopic) or long-sighted (hyperopic)

• Have diabetes or other systemic health conditions

• Have had previous eye injury or surgery

• Use steroid medications long-term

How Glaucoma Is Diagnosed

At Rose Optometry, we use advanced technology to detect glaucoma early and monitor it accurately over time. Our comprehensive glaucoma assessments may include:

• Tonometry – measures the pressure inside your eye

• Visual Field Testing (VF) – checks for any loss of peripheral vision

• Optical Coherence Tomography (OCT) – provides detailed imaging of the optic nerve and retinal layers

These tests allow us to detect even subtle changes before vision is affected.

Treatment and Management

While glaucoma cannot be cured, early detection and treatment can slow or prevent vision loss.

Treatment options may include:

• Prescription eye drops to lower eye pressure

• Laser treatment

• Surgery (in more advanced cases)

We work closely with your ophthalmologist when required to ensure you receive the most appropriate care and long-term management.

Why Early Detection Is Critical

Vision lost from glaucoma cannot be restored. However, with early diagnosis and ongoing monitoring, most people with glaucoma can maintain good vision for life.

Regular eye exams are your best defence.
