Understanding Glaucoma: The Silent Thief of Sight

Glaucoma is a group of eye diseases that damage the optic nerve, usually due to high pressure inside the eye. It is one of the leading causes of irreversible blindness worldwide, yet many people are unaware they have it.

Why Is It Silent?

In its most common form, open-angle glaucoma, there are no symptoms in the early stages. Vision loss begins at the periphery — your side vision — and progresses so gradually that many people do not notice until significant damage has occurred.

Who Is at Risk?

Glaucoma is more common in people over 40, those with a family history of the condition, individuals with high eye pressure, and people of African, Asian, or Hispanic descent. Diabetes and high blood pressure also increase your risk.

How We Detect It

A comprehensive eye exam includes several glaucoma checks: measuring your intraocular pressure, examining the optic nerve, testing your visual field, and using OCT imaging to measure nerve fibre thickness. These tests are painless and take only a few minutes.

Treatment Works

Glaucoma cannot be reversed, but it can be controlled. Prescription eye drops, laser treatment, and surgery can lower eye pressure and prevent further vision loss. The key is early detection — before you notice any symptoms.

If you are over 40 and have not had a comprehensive eye exam in the last year, we recommend booking one. It could save your sight.
