Comprehensive Glaucoma Services in Singapore ā Diagnosis, Treatment and Surgery
What Is Glaucoma?
Glaucoma is a group of eye diseases that can lead to vision loss and blindness due to damage to the optic nerve. Often called the āsilent thief of sight,ā glaucoma progresses gradually, with many patients unaware of their condition until significant vision impairment occurs. Early detection and proper treatment are crucial in preventing irreversible vision loss.
Why Is It Important To Diagnose And Treat Glaucoma Early?
Glaucoma is the leading cause of irreversible blindness.Ā The number of people with this condition in Asia is estimated to increase from 59 million in 2020 to 80 million in 2040.
In Singapore, 3% of people over the age of 50, and 10% of those over the age of 70 have Glaucoma.
While Glaucoma is not curable, blindness is preventable if checked, diagnosed and treated early. There are usually no warning signs; Glaucoma is usually detected from doing regular eye tests with your Eye Specialists.
Glaucoma Symptoms: How to Spot the Warning Signs
As the disease can develop slowly, you may not be aware of the gradual loss of sight until very late in the disease when there is tunnel vision.
Symptoms of primary open-angle glaucoma or chronic angle closure glaucoma include:
- Patchy blind spots/gradual loss in your side vision (peripheral vision), frequently in both eyes.Ā
- Tunnel vision (advanced stages)
Symptoms of acute angle-closure glaucoma include:
- Severe headache and eye pain
- Nausea and vomiting (accompanying the severe eye pain)
- Sudden onset of visual disturbance, often in low light
- Blurred vision
- Halos around lights
- Eye redness
When to See an Eye Specialist?
If you experience any of these symptoms, especially if you have a family history of glaucoma, schedule an eye exam immediately. Early intervention can prevent vision loss.
Risk Factors Of Glaucoma
Risk factors of glaucoma include:
- Age. Your risk increases when you are over 60 years old.
- Chronic diseases. You are at increased risk if you have diabetes, high blood pressure or heart diseases.Ā
- Ethnicity. Asians are more susceptible to angle-closure glaucoma than Caucasians.
- History of traumatic eye injuries or certain types of eye surgeries.
- Family history
- Use of corticosteroids (whether as eye medications or oral form)
- Refractive error (short-sightedness or myopia is a risk factor for open-angle glaucoma and far-sightedness or hyperopia for closed angle glaucoma)
Types Of Glaucoma
Chronic Glaucoma:Ā results fromĀ graduallyĀ increasing eye pressure which slowly causes irreversible damage to the eye. This condition usually shows no early symptoms and thus often goes undetected without regular eye checks. Left untreated, chronic glaucoma can cause partial or total vision loss.
There are two main types of chronic primary glaucoma:
- Primary Open-Angle Glaucoma (POAG)
- Primary Angle-Closure Glaucoma (PACG)
Acute glaucoma is regarded as aĀ medical emergencyĀ because optic nerve damage and consequent loss of vision can occur extremely rapidly (within hours or days). Look out for symptoms such as one-sided headache, nausea and vomiting, haloes, eye pain, and blurring of vision. If you are experiencing such symptoms, consult a doctor immediately. If such a situation occurs after usual clinic hours, we recommend going to A&E ā do not wait until the next day.
Normal Tension Glaucoma:Ā also known as low tension or normal pressure glaucoma, is a form of open angle glaucoma in which damage occurs to the optic nerve without eye pressure exceeding the normal range. In general, a ānormalā pressure range is between 10 to 21 mm Hg. Currently, this condition is still not fully understood. However, evidence has shown that lowering intraocular pressure can help to slow its progression.
Secondary Glaucoma:Ā refers to any form ofĀ glaucomaĀ in which there is an identifiable cause of increased eye pressure, resulting in optic nerve damage and vision loss. As with primaryĀ glaucoma,Ā secondary glaucomaĀ can be open-angled or closed-angled and it can occur in one or both eyes. It may be caused by previous eye injury, inflammation (which can be related to autoimmune diseases), certain drugs such as steroids, diabetes mellitus and hyper-mature cataracts.
Childhood Glaucoma:Ā is a rare condition that can start developing in infancy, childhood, or adolescence. It may cause enlargement of the infantās eyes, corneal haze, tearing and unusual light sensitivity.
What Are The Treatment Options For Glaucoma?
Glaucoma cannot be cured, but in most cases it can be successfully controlled.Ā Treatment will depend on the type of glaucoma you are diagnosed with.
Glaucoma treatments include:
- Eye drops and oral medications
- Laser procedures
- Minimally Invasive Glaucoma Surgery (MIGS)
- Filtering surgery with or without drainage implants.
Currently, the mainstay of glaucoma treatment is to lower intraocular pressure so as to reduce disease progression. Treatment is life-long, and can be achieved with topical medications, laser or surgery.
Glaucoma Surgery Options: When Is Surgery Necessary?
For patients with moderate to severe glaucoma, surgery may be recommended to reduce intraocular pressure and prevent further vision loss.
Who Needs Surgery?
- Patients whose eye pressure remains high despite medication
- Those experiencing progressive vision loss
- Individuals at risk of complete optic nerve damage
