Glaucoma: What It Is, How to Spot It, and Why Early Detection Matters

Glaucoma is one of the leading causes of irreversible vision loss worldwide—and the scariest part? It often develops without any symptoms until significant damage has already occurred. That’s why understanding what glaucoma is, how to spot the early warning signs, and getting regular eye examinations is so important.

What Is Glaucoma?

Glaucoma refers to a group of eye conditions that damage the optic nerve, which is crucial for good vision. This damage is often caused by abnormally high pressure in the eye (intraocular pressure), though it can also occur even with normal eye pressure. The most common type, open-angle glaucoma, develops slowly and painlessly, which means many people don't realise they have it until it's too late.

How to Spot the Early Signs of Glaucoma

Although early glaucoma is often symptomless, here are some potential warning signs to look out for:

• Gradual loss of peripheral (side) vision

• Blurred or tunnel vision, especially in advanced stages

• Eye pain or pressure

• Redness in the eye

• Halos around lights

• Sudden vision loss (a medical emergency in rare forms like acute angle-closure glaucoma)

Because symptoms can be so subtle, the best way to detect glaucoma early is through regular comprehensive eye exams.

What You Should Do

If you're over 40, have a family history of glaucoma, are diabetic, or are of African, Asian, or Caribbean descent, you're at a higher risk. Routine eye exams can catch glaucoma early—before significant vision loss occurs. Once diagnosed, glaucoma can often be managed with eye drops, medication, laser treatment, or surgery.
