Glaucoma

Gambaran keseluruhan

Glaucoma is a group of eye conditions that damage the optic nerve, which connects your eye to your brain. It often happens when fluid builds up in the front part of the eye, causing too much pressure. This can lead to vision loss if not treated.

Yes, glaucoma is common, especially in people over 60. It affects about 1 in 200 people by age 50, and up to 1 in 10 by age 80.

Glaucoma can affect anyone, but it is more common in older adults, people with a family history of glaucoma, those of African or Caribbean descent, and people with certain medical conditions like diabetes.

Gejala

Gejala biasa

• Glaucoma often has no early symptoms. As it progresses, you may notice loss of side (peripheral) vision, tunnel vision, or blurred vision.

Gejala pada kanak-kanak

• In children, glaucoma may cause cloudy eyes, sensitivity to light, excessive tearing, or one eye appearing larger than the other.

Gejala pada orang dewasa yang lebih tua

• Older adults may notice gradual loss of side vision, difficulty adjusting to dark rooms, or needing more light to see clearly.

Punca

Punca utama

• Glaucoma is usually caused by a build-up of fluid inside the eye, which increases pressure. This pressure damages the optic nerve over time.
• Some types of glaucoma have no clear cause, but genetics and other health conditions may play a role.

Faktor risiko

• Age over 60
• Family history of glaucoma
• Being of African, Caribbean, or Asian descent
• Certain medical conditions like diabetes, high blood pressure, or nearsightedness
• Long-term use of steroid medications

Bila perlu berjumpa doktor

Jumpa doktor dengan segera jika:

• If you experience sudden severe eye pain, redness, or vision changes, call your local emergency number or go to an emergency room immediately.

Buat temujanji rutin jika:

• If you are over 40, have a family history of glaucoma, or have other risk factors, schedule an eye exam every one to two years even if you have no symptoms.

Diagnosis

An eye doctor (optometrist or ophthalmologist) will perform a series of painless tests to check for glaucoma. These tests measure eye pressure, examine the optic nerve, and check your field of vision.

Ujian yang mungkin dilakukan

• Tonometry – a test that measures the pressure inside your eye
• Ophthalmoscopy – examining the optic nerve with a special light
• Perimetry (visual field test) – checking your side vision
• Pachymetry – measuring the thickness of your cornea

Apa yang diharapkan semasa temujanji anda

The tests are quick and painless. Your eyes may be numbed with drops before some tests. The results will tell your doctor if you have glaucoma or are at risk, and they will discuss next steps.

Rawatan

Treatment aims to lower pressure inside the eye to prevent further optic nerve damage. It usually starts with medicated eye drops that help fluid drain more easily. If drops are not enough, you may need laser or surgical procedures. Treatments cannot restore lost vision, but they can slow or stop further loss.

Penjagaan diri di rumah

• Take prescribed eye drops exactly as directed – do not skip doses.
• Keep all follow-up appointments with your eye doctor to monitor pressure and vision.
• Tell your doctor about any other medications you take, as some can affect eye pressure.

Rawatan perubatan

The main medical treatment is prescription eye drops that reduce fluid production or improve drainage. Your doctor may also recommend laser procedures, such as 'laser trabeculoplasty', which helps fluid drain better. Oral medications are sometimes used if drops alone are not enough.

Bila pembedahan dipertimbangkan?

If eye drops and laser treatments do not control the pressure, surgery such as 'trabeculectomy' (creating a new drainage channel) or implanting a tiny drainage device may be recommended. These are usually done under local anaesthetic and can help preserve remaining vision.

Hidup dengan keadaan ini

Living with glaucoma means taking your drops as prescribed, attending regular eye check-ups, and keeping a healthy lifestyle. Most people with glaucoma can continue their daily activities, including driving, as long as their vision meets legal standards.

Tip gaya hidup

• Protect your eyes from injury by wearing safety glasses during sports or DIY work.
• Avoid activities that involve heavy lifting or straining, as these can temporarily raise eye pressure.
• If you have side vision loss, take extra care when walking in crowded areas or at night.

Diet dan senaman

Eat a balanced diet rich in fruits, vegetables, and omega-3 fatty acids. Regular moderate exercise like walking or swimming may help lower eye pressure. But check with your doctor before starting a new exercise routine, as some positions (like head-down yoga) can raise pressure.

Kesihatan mental dan kesejahteraan emosi

A glaucoma diagnosis can be worrying, but you are not alone. Many people cope well with support from family, friends, and healthcare teams. If you feel anxious or depressed, talk to your doctor – they can connect you with counselling or support groups.

Pencegahan

Glaucoma cannot be prevented, but regular eye exams can catch it early when treatment is most effective. If you have risk factors, getting your eyes checked every one to two years is key.

Program saringan

People over 40 with risk factors should have regular eye exams. Some health systems offer free glaucoma screening tests. Check with your local eye care provider for recommendations in your area.

Komplikasi

Jika tidak dirawat

• Progressive vision loss starting from the sides (peripheral vision)
• Tunnel vision – only being able to see straight ahead
• Complete blindness in the affected eye(s)

Pandangan jangka panjang

With early detection and proper treatment, most people with glaucoma can maintain useful vision for life. While some vision loss may occur, treatment can slow down the process. Many people manage glaucoma well and continue to enjoy everyday activities.
