Glaucoma is often referred to as the "silent thief of sight," and for good reason. This group of eye conditions can lead to irreversible vision loss without significant early symptoms, making it one of the most insidious threats to your eye health.

Understanding glaucoma, its causes, symptoms, detection methods, and the crucial role of regular eye examinations cannot be overstated.

What is Glaucoma?

Glaucoma is not a single condition but a group of eye diseases that primarily affect the optic nerve, which carries visual information from the eye to and from the brain.

The most common form of glaucoma, primary open-angle glaucoma, is characterised by an increase in intraocular pressure (IOP), or pressure within the eye, which can damage the optic nerve over time.

Glaucoma remains a significant challenge in the realm of eye health, largely due to its silent progression and potential for irreversible damage. However, with advances in medical science and the dedicated efforts of ophthalmologists, there is hope for those affected by this condition.

Regular eye examinations, early detection, and timely intervention are the cornerstones of preventing vision loss due to glaucoma.

Causes of Glaucoma?

The exact cause of glaucoma is not fully understood, but the condition is largely associated with increased intraocular pressure. In a healthy eye, a fluid called aqueous humor circulates and drains out, maintaining a stable pressure. In glaucoma, this fluid doesn't drain properly, leading to increased pressure that can damage the optic nerve.

Risk factors for glaucoma include age (individuals over 60 are at higher risk), a family history of the condition, certain medical conditions like diabetes, shortsightedness and race.

Symptoms of Glaucoma

In its early stages, glaucoma often presents no symptoms, which is why it can progress unnoticed until significant vision loss occurs.

For more advanced stages, symptoms may include:

• Patchy blind spots in peripheral or central vision, usually in both eyes

• Tunnel vision in advanced stages

Acute angle-closure glaucoma, a less common form, can present sudden symptoms like severe eye pain, nausea, redness in the eye, and blurred vision. This requires immediate medical attention.

Detecting Glaucoma

Early detection through regular eye exams is crucial to managing glaucoma and preventing significant vision loss.

Comprehensive eye exams should include:

• Measurement of intraocular pressure (tonometry)

• Testing for optic nerve damage with a dilated eye exam

• Optical coherence tomography (OCT) to obtain detailed images of the retina

• Visual field tests to detect loss of peripheral vision

• Inspection of the drainage angle (gonioscopy)

Regular eye check-ups are critical because glaucoma can progress unnoticed until irreversible damage has occurred. Early detection allows for treatment options that can slow or prevent further vision loss.

The Importance of Regular Eye Check-Ups

Regular eye examinations are essential for detecting glaucoma at an early stage, especially for those at higher risk.

Our team of world-class leading ophthalmologists recommend comprehensive eye exams every one to two years for adults over the age of 40 and annually for those over 60 or with risk factors for glaucoma.
