Care / Glaucoma

Glaucoma

Glaucoma is often called the silent thief of sight — most people don't notice anything until vision is already lost. Our doctors specialise in catching it early through careful imaging, pressure checks, and optic nerve assessment, then walking you through what your results mean.

What is Glaucoma

There are 2 types of Glaucoma

Glaucoma is a group of eye diseases that damage the optic nerve - the cable carrying visual signals from the eye to the brain. The damage can begin gradually and may go unnoticed for years.

Open-angle glaucoma

The drainage system remains open but does not remove fluid efficiently. It may occur with high eye
pressure or with pressure in the normal range, known as normal-tension glaucoma.

Closed-angle glaucoma

The drainage angle becomes too narrow or closes. It may develop gradually, or suddenly as acute
closed-angle glaucoma - a medical emergency.
Glaucoma damage cannot be reversed. Treatment can slow or stop further damage, but it cannot
restore vision that has already been lost. Early detection gives us the best chance to protect your sight.

Only a specialist examination can confirm the type and stage.

WHAT IS GLAUCOMA AND SYMPTOMS

Glaucoma often has no early symptoms

In most cases of open-angle glaucoma, there are no noticeable symptoms in the early stages. By the time vision changes become obvious, damage may already be significant and irreversible. Regular eye examinations are essential for early detection.

Gradual loss of side vision

Blind spots or tunnel vision

Blurred or hazy vision

Difficulty adjusting to low light

Trouble seeing while driving at night

Bumping into objects at either side

EMERGENCY MESSAGE

Acute or Closed-angle glaucoma: seek urgent care

Sudden severe eye pain, a red eye, blurred or reduced vision, halos around lights, headache, nausea, or
vomiting may indicate acute closed-angle glaucoma. This is an eye emergency. Seek immediate medical
attention.

Why screening matters

You cannot feel Glaucoma
until it is too late...

Early damage goes unnoticed

Glaucoma can silently affect your side vision long before you notice any changes.

Normal eye pressure does not exclude glaucoma

Normal eye pressure does not rule out glaucoma. Diagnosis also requires assessment of the optic nerve, visual field and other clinical findings.

Who should consider glaucoma screening?

You should consider glaucoma screening if you:

Have a family history of glaucoma

Have high myopia (nearsightedness)

40+

Are aged 40 or older

Have diabetes

Have high blood pressure or vascular disease

Have had an eye injury or steroid use (eye drops, pills, or inhalers)

Are of African, Hispanic, or Asian descent

Wear contact lenses long-term

Regular comprehensive eye exams are the best way to detect glaucoma early, before vision is affected.
