Glaucoma is one of the leading causes of irreversible blindness worldwide, yet many people donʼt realise they may be at risk. It often develops without obvious warning signs, which is why it is called the ‘silent thief of sightʼ. Understanding this condition and taking proactive steps can make all the difference in preserving your eyesight.

“The symptoms of glaucoma are usually very subtle and painless in the early stages,ˮ says

Dr. Alicia Swaby-Spencer, an ophthalmologist at the Mandeville Regional Hospital. “It progresses slowly and affects the peripheral or side vision first while the central vision remains intact.ˮ

This subtlety is what makes glaucoma so dangerous. Vision loss can become permanent before anyone realises something is wrong.

What Happens Inside the Eye?

Glaucoma usually results from high pressure inside the eye that damages the optic nerve, the crucial pathway sending visual information to the brain. Dr. Swaby-Spencer notes that these nerves within the central nervous system cannot be repaired, which leads to permanent damage. If untreated, this damage causes irreversible vision loss.

Early diagnosis is key to protecting your sight. When glaucoma is caught early, eye pressure can often be controlled with daily eye drops, preventing further damage and blindness.

Adults should start routine eye screenings from around age 40. However, you should begin screening earlier if you have a family history of glaucoma, or you have diabetes, hypertension or high myopia (severe nearsightedness).

Managing Glaucoma

Once diagnosed, managing glaucoma typically involves:

• Daily use of prescribed drops to control eye pressure
• Routine pressure checks and comprehensive eye exams
• Visual field tests to monitor vision
• Possible minor surgery if medication isnʼt enough

Consistency is vital for effective glaucoma management. Try these tips to build eye drop use into your daily routine:

• Keep your eye drops in a visible place like your bedside table or bathroom sink
• Set reminders on your phone
• Place your medication where you carry out other daily habits

Take Control of Your Eye Health

Glaucoma may be a silent thief, but it doesnʼt have to steal your sight. With regular screening, early action and adherence to treatment, you can protect your vision for years to come. Fortunately, glaucoma is covered by the NHFCard, which allows you to access the medication you need at subsidised costs. Be sure to apply if you do not have yours yet.
