青光眼治疗
Glaucoma is the leading cause of irreversible blindness in Singapore, responsible for 40% of all cases of blindness in the country.
Known as the “Silent Thief of Sight”, it often develops without any pain or noticeable vision loss in its early stages. By the time most patients notice a problem, significant and irreversible damage has already occurred.
What is Glaucoma?
Glaucoma is a group of eye conditions that cause progressive damage to the optic nerve, which is the nerve that carries visual signals from the eye to the brain. Once the optic nerve fibres are damaged, the vision loss is permanent and irreversible. This is why glaucoma is known as the 'Silent Thief of Sight': most patients lose a significant amount of vision before they notice any symptoms at all.
In many cases, glaucoma is associated with elevated pressure due to a build-up of fluid inside the eye. Over time, the increased pressure can damage the optic nerve fibres. Left untreated, glaucoma can progress from peripheral vision loss to tunnel vision and, in severe cases, blindness. However, with early detection and appropriate treatment, the progression of glaucoma can be significantly slowed, allowing most patients to maintain functional vision throughout their lifetime.
What Are the Symptoms of Glaucoma?
One of the most concerning aspects of glaucoma is that it is often asymptomatic in its early and moderate stages, particularly primary open-angle glaucoma, which typically causes no pain or noticeable changes in vision until the disease is advanced.
As the condition progresses, symptoms may include:
- Gradual loss of peripheral (side) vision
- Tunnel vision in advanced stages
By the time a patient notices peripheral vision loss or "tunnel vision" in their daily life, significant and irreversible damage to the optic nerve has often already occurred. This is why regular eye examinations are important for detecting glaucoma before symptoms develop.
- Sudden, severe eye pain
- Blurred vision or sudden vision loss
- Rainbow-coloured halos around lights
- Severe headache
- Nausea and vomiting
If you experience the sudden onset of these symptoms, seek immediate medical attention, as prompt treatment may help prevent permanent vision loss.

What Are the Different Types of Glaucoma?
There are several types of glaucoma, each with different causes and treatment approaches. Identifying the type of glaucoma is an important part of planning appropriate treatment.
Primary Open-Angle Glaucoma
Primary open-angle glaucoma is the most common type of glaucoma. The eye’s drainage angle remains open, but the drainage system becomes less efficient over time, causing pressure to build up gradually. It usually develops slowly and often causes no noticeable symptoms until vision loss has occurred.
Primary Angle-Closure Glaucoma
Primary angle-closure glaucoma occurs when the drainage angle between the iris and cornea becomes narrowed or blocked, preventing fluid from draining normally. This can cause a sudden rise in eye pressure and is a medical emergency, although some cases develop more gradually.
Normal-Tension Glaucoma
Normal-tension glaucoma causes optic nerve damage even though eye pressure remains within the normal range. Comprehensive eye examinations are important, as eye pressure measurements alone may not detect this condition.
Secondary Glaucoma
Secondary glaucoma develops as a result of another eye condition or medical problem, such as prolonged steroid use, eye injury, inflammation or diabetic eye disease. Treatment focuses on managing both the underlying cause and the glaucoma.
Paediatric Glaucoma
Paediatric glaucoma is a rare condition that affects infants and children. Early diagnosis and treatment are important to help preserve vision and support healthy visual development.
How Does Our Clinic Provide Treatment Options for Glaucoma?
At our clinic, our glaucoma treatment methods focus on lowering eye pressure and slowing damage to the optic nerve. Appropriate treatment approaches depend on the type and severity of glaucoma, as well as your individual eye condition.
Eye Drops
Eye drops are often the first treatment for glaucoma. Different medications lower eye pressure by reducing fluid production, improving drainage or both. Your ophthalmologist will recommend the most suitable medication and monitor your response over time.
Laser treatment may be recommended if eye drops are unsuitable or do not adequately control eye pressure. Depending on the type of glaucoma, laser procedures can improve fluid drainage or help prevent acute angle-closure glaucoma.
Surgery may be considered when glaucoma cannot be adequately controlled with eye drops or laser treatment. Depending on your condition, options may include minimally invasive glaucoma surgery (MIGS), trabeculectomy or tube shunt surgery to lower eye pressure and help preserve vision.
Early Glaucoma Diagnosis Can Help Preserve Your Vision
Glaucoma requires ongoing monitoring and timely treatment to help slow disease progression and preserve vision. With the right management, many patients are able to maintain functional vision for many years.
At Dr Leo Adult & Paediatric Eye Specialist Clinic, Senior Consultant Ophthalmologist Dr Leo Seo Wei provides comprehensive glaucoma assessment and personalised treatment plans tailored to your condition. Whether you require ongoing monitoring, medical therapy, laser treatment or glaucoma surgery, our clinic aims to help preserve your vision through timely diagnosis and appropriate care.

青光眼是通过全面的眼部检查来诊断的，其中可能包括：
- 眼压测量（眼压计）
- 视神经评估
- 视野检查
- OCT（光学相干断层扫描）成像
- 角膜厚度测量
- 房角镜检查以检查引流角
是的。青光眼是全球不可逆失明的主要原因之一。然而，早期检测和适当治疗可以显著降低严重视力丧失的风险。
当眼内的房水无法正常排出，或产生速度超过排出速度时，眼压就会升高。眼压升高是青光眼的主要风险因素，会随时间损害视神经。
是的。这被称为正常眼压性青光眼。有些人在眼压处于正常范围内的情况下仍会出现视神经损伤。
青光眼目前无法治愈，由青光眼引起的视力丧失也无法逆转。然而，治疗可以有效减缓青光眼的进展，并在许多患者中防止进一步的视力丧失。
青光眼并不总是可以预防的，但通过定期眼部检查进行早期检测是防止严重视力丧失的最佳方法。
