If you have recently been diagnosed with glaucoma, one of the first questions you may ask is: can glaucoma be cured?
At present, glaucoma cannot usually be cured, and any vision already lost because of the condition cannot normally be restored. However, effective treatment can reduce pressure inside the eye and help slow or prevent further damage to the optic nerve.
For many patients, glaucoma can be successfully managed for years with regular monitoring and the right treatment plan.
At The Medical Eye Clinic in Exeter, our consultant ophthalmologists provide specialist assessment, monitoring and treatment for glaucoma, with care tailored to the individual patient and the type and severity of their condition.
What Is Glaucoma?
Glaucoma is the name given to a group of eye conditions that damage the optic nerve, which carries visual information from the eye to the brain.
The condition is commonly associated with increased pressure inside the eye, known as intraocular pressure (IOP).
However, glaucoma can sometimes occur even when eye pressure falls within what would normally be considered a typical range.
Damage to the optic nerve tends to happen gradually. In the early stages, many people experience no obvious symptoms, which is why regular eye examinations are so important.
Without treatment, glaucoma can lead to permanent loss of vision.
So, can glaucoma be cured?
Currently, there is no treatment that can reverse optic nerve damage that has already occurred.
The aim of glaucoma treatment is therefore to:
- Reduce pressure inside the eye
- Protect the optic nerve from further damage
- Slow or stop progression of the condition
- Preserve as much vision as possible
With appropriate treatment and regular monitoring, many people with glaucoma continue to maintain useful vision throughout their lives.
This is why early diagnosis is particularly important. The sooner the condition is identified, the sooner treatment can begin to protect the vision you still have.
Why Is Eye Pressure Important in Glaucoma?
The eye constantly produces a clear fluid called aqueous humour.
This fluid normally drains away through tiny drainage channels in the front of the eye. If drainage becomes less efficient, pressure can build up.
Over time, increased pressure may damage the optic nerve.
Lowering eye pressure is currently the main proven method of reducing the risk of further glaucoma damage.
Your ophthalmologist will determine an appropriate target pressure based on factors including:
- Your current eye pressure
- The amount of optic nerve damage present
- Your visual field results
- The type of glaucoma you have
- Your age and overall eye health
- How quickly the condition appears to be progressing
Treatment can then be adjusted if necessary.
What Are the Main Treatments for Glaucoma?
There are several ways to lower eye pressure.
The most suitable option depends on your type of glaucoma, how advanced it is and how well your eye responds to treatment.
Eye Drops
Prescription eye drops are one of the most commonly used treatments for glaucoma.
Different types of drops work in different ways. Some reduce the amount of fluid produced inside the eye, while others improve the drainage of fluid.
Eye drops are often very effective, but they usually need to be used regularly and consistently.
It is important to follow your prescribed schedule carefully, even if your eyes feel completely normal. Glaucoma often progresses without noticeable symptoms, so the absence of symptoms does not mean treatment is no longer needed.
If you experience side effects or find it difficult to use your drops, speak to your ophthalmologist rather than stopping them yourself.
Selective Laser Trabeculoplasty (SLT)
Selective Laser Trabeculoplasty, often shortened to SLT, is a laser treatment used for certain types of glaucoma.
SLT applies controlled laser energy to the eye’s drainage system, helping improve the flow of fluid out of the eye and lower intraocular pressure.
It may be considered:
- As an alternative to starting eye drops
- Alongside existing medication
- When eye drops are not controlling pressure sufficiently
- When patients experience problems using glaucoma drops
The procedure is usually performed on an outpatient basis and does not involve surgical incisions.
The effect can vary between individuals, and some patients may still require medication or further treatment in the future.
Minimally Invasive Glaucoma Surgery
Some patients may be suitable for minimally invasive glaucoma surgery (MIGS).
These procedures are designed to improve fluid drainage from the eye while generally involving less disruption to the surrounding tissues than traditional glaucoma surgery.
One example is iStent, a tiny implant placed into the eye’s natural drainage pathway.
iStent may be considered for suitable patients with open-angle glaucoma and can sometimes be performed alongside cataract surgery.
The aim is to help lower eye pressure and, for some patients, reduce their reliance on glaucoma medication.
Your consultant can advise whether a minimally invasive treatment is appropriate for you.
Glaucoma Surgery
If eye drops, laser treatment or minimally invasive procedures do not control eye pressure sufficiently, more traditional glaucoma surgery may be recommended.
Surgery aims to create or improve a pathway through which fluid can leave the eye, thereby lowering intraocular pressure.
The most appropriate procedure will depend on the individual patient and the severity of their glaucoma.
As with all surgical treatment, your ophthalmologist will discuss the potential benefits, risks and expected outcomes with you beforehand.
Does Glaucoma Treatment Restore Lost Vision?
Unfortunately, vision already lost because of glaucoma cannot usually be restored.
This is because the condition damages the optic nerve, and current treatments cannot regenerate nerve tissue that has already been permanently damaged.
Instead, treatment is focused on preserving remaining vision.
This is one of the reasons glaucoma screening and early diagnosis are so important.
A person can lose a considerable amount of peripheral vision before noticing a problem themselves.
How Is Glaucoma Monitored?
Glaucoma is usually a long-term condition, so monitoring remains important even when your eye pressure is well controlled.
Your appointments may include:
- Measurement of intraocular pressure
- Examination of the optic nerve
- Visual field testing
- Optical coherence tomography (OCT)
- Assessment of the eye’s drainage angle
- Review of your medication and treatment response
These tests allow your ophthalmologist to identify subtle changes over time and determine whether treatment needs to be adjusted.
Can Glaucoma Get Worse Even With Treatment?
In some cases, glaucoma can continue to progress despite treatment.
This does not necessarily mean that treatment has failed. Your eye pressure may need to be lowered further, or the condition may require a different treatment approach.
Regular monitoring allows changes to be detected as early as possible.
If there is evidence that glaucoma is progressing, your specialist may recommend:
- Changing or adding eye drops
- Laser treatment
- A minimally invasive procedure
- Glaucoma surgery
Treatment plans are therefore often adjusted over time according to how the eye responds.
Can Lifestyle Changes Help Glaucoma?
Lifestyle changes cannot replace medical treatment, but maintaining good general health can support overall eye health.
You may be advised to:
- Attend all scheduled eye appointments
- Take glaucoma medication exactly as prescribed
- Maintain a generally healthy lifestyle
- Avoid smoking
- Discuss significant changes to medication with your healthcare team
- Tell close relatives if you have glaucoma
Family history is important because some types of glaucoma are more common among people who have a close relative with the condition.
If glaucoma runs in your family, relatives may benefit from regular eye examinations.
What Happens If Glaucoma Is Left Untreated?
Untreated glaucoma can cause progressive and permanent vision loss.
Damage often begins in the peripheral vision and can gradually extend towards the centre of the visual field.
Because this process can occur without pain or obvious symptoms, someone may not realise their sight is deteriorating until substantial damage has occurred.
Treatment cannot restore vision that has already been lost, making early detection and ongoing management particularly important.
Is Glaucoma Treatment Lifelong?
For many people, glaucoma requires lifelong monitoring.
Treatment may also need to continue indefinitely, although the type of treatment can change.
For example, someone who initially manages their glaucoma with eye drops may later have SLT or another procedure.
The goal throughout is the same: keeping eye pressure at an appropriate level and protecting the optic nerve from further damage.

Frequently Asked Questions
Can glaucoma be cured permanently?
At present, glaucoma cannot usually be cured permanently. However, treatment can lower eye pressure and help prevent or slow further damage to the optic nerve.
Can glaucoma vision loss be reversed?
Vision already lost due to glaucoma cannot normally be restored. Treatment focuses on protecting the remaining vision and preventing further deterioration.
What is the best treatment for glaucoma?
There is no single treatment that is best for everyone. Treatment may include eye drops, SLT laser treatment, minimally invasive glaucoma surgery or conventional surgery depending on the patient’s condition.
Can glaucoma be stopped from getting worse?
Treatment can significantly reduce the risk of glaucoma progressing. Regular monitoring is important because treatment may need to be adjusted if further changes are detected.
Do you have to use glaucoma eye drops forever?
Some patients use eye drops long term, while others may be able to reduce their dependence on drops after laser or surgical treatment. Your ophthalmologist will advise what is appropriate for you.
Can glaucoma cause blindness?
If left untreated, glaucoma can cause severe and permanent sight loss. Early diagnosis and effective treatment significantly reduce the risk of this happening.
