Glaucoma is often described as the ‘Silent Thief of Sight’ because it frequently lacks noticeable early symptoms. In the UK, it is a leading cause of preventable blindness, affecting over 700,000 people. As we move through 2025 and onto 2026, the medical community’s approach has shifted from simply monitoring eye pressure to aggressive, early intervention designed to stop nerve damage before it begins.
Whether you have been diagnosed with ocular hypertension or are concerned about a family history of the disease, understanding your options for glaucoma treatment, ranging from laser treatment for eyes to advanced glaucoma surgery, is essential for long-term vision protection.
Recognising Glaucoma Symptoms: The Early and Advanced Stages
In its most common form, Primary Open-Angle Glaucoma, there are virtually no early symptoms. The loss of vision is so gradual that the brain compensates for the “blind spots” until the disease is advanced. However, as the condition progresses, patients may notice:
- A subtle loss of peripheral (side) vision.
- Difficulty seeing in low light or “night blindness.”
- Occasional blurred vision.
A far more urgent situation is acute glaucoma (Angle-Closure Glaucoma). This is a medical emergency where eye pressure spikes rapidly. The glaucoma symptoms in these cases are impossible to ignore: sudden, severe eye pain, nausea, vomiting, and seeing rainbow-coloured halos around lights. If you experience these, you must seek an urgent ophthalmology consultation immediately to prevent permanent sight loss.
Ocular Hypertension: The Warning Sign
Many patients visit a clinic after a routine optician’s check reveals high eye pressure, often referred to as ocular hypertension. Having ocular hypertension does not mean you have glaucoma, but it does mean you are at a significantly higher risk. Clinical data for 2025 suggests that approximately 10% of untreated patients with high eye pressure will develop glaucoma within a decade.
The goal of glaucoma treatment at this stage is preventative. By managing eye pressure early, we can protect the delicate retinal ganglion cells. According to NICE Guidelines (UK), treatment is typically considered when the pressure consistently exceeds 24mmHg, or if the patient’s cornea is naturally thin.
The Shift to Laser Treatment for Eyes
One of the most significant changes in UK ophthalmic care in 2024-2025 is the move toward laser treatment for eyes as a first-line therapy. Specifically, Selective Laser Trabeculoplasty (SLT) has become the gold standard.
Unlike traditional eye drops, which can be difficult to remember and may cause redness, SLT is a gentle, 10-minute outpatient procedure. This laser treatment for eyes works by using a specific wavelength to stimulate the eye’s natural drainage system, effectively lowering eye pressure by up to 30%. For many patients, this eliminates the need for daily medication while providing superior stability in their glaucoma treatment journey.
Advanced Glaucoma Surgery: Precision in 2025
When medications and laser treatment for eyes are no longer sufficient to keep eye pressure within a safe range, glaucoma surgery becomes the necessary next step. Modern glaucoma surgery has been revolutionised by Minimally Invasive Glaucoma Surgery (MIGS).
In 2025, surgeons like Mr Manu Mathew utilise microscopic stents (such as the iStent inject® W) that can be inserted during routine cataract surgery. These devices provide a permanent bypass for fluid, ensuring continuous eye pressure control with a very high safety profile. For more advanced or resistant cases, traditional glaucoma surgery like a trabeculectomy remains a highly effective “gold standard,” creating a new drainage pathway to achieve significantly lower pressures.
Managing Acute Glaucoma and Emergency Care
As mentioned, acute glaucoma requires immediate intervention. The initial glaucoma treatment for an acute attack involves powerful intravenous medications and eye drops to force the pressure down. Once the pressure is stabilised, a specific laser treatment methodology called Peripheral Iridotomy (PI) is performed. This creates a tiny, invisible hole in the iris to prevent future “attacks” of acute glaucoma. Understanding these symptoms and acting within hours can make the difference between a full recovery and permanent blindness.
How to Relieve Winter Dry Eyes
Thankfully, a little knowledge and a few small changes can make a big difference. Here are several strategies approved by our very own Mr Mathew for dry eye relief during the winter months:

Frequently Asked Questions (FAQs)
1. What are the first glaucoma symptoms I should look for?
Usually, there are no symptoms in the early stages. The first sign is often a loss of peripheral vision, which is why regular eye pressure checks are vital.
2. Can ocular hypertension be cured?
Ocular hypertension cannot be “cured” in a permanent sense, but it can be perfectly managed with glaucoma treatment to prevent it from ever turning into glaucoma.
3. What makes acute glaucoma a medical emergency?
In acute glaucoma, the pressure rises so fast that it can kill the optic nerve within hours. Immediate glaucoma treatment is required to save the eye.
4. How long is the recovery after glaucoma surgery?
With modern MIGS-style glaucoma surgery, recovery is very fast, often within a few days. Traditional surgeries like trabeculectomy may take a few weeks to stabilize.
5. Does high eye pressure always mean I have glaucoma?
No. High eye pressure (ocular hypertension) is a risk factor, but glaucoma is only diagnosed when there is actual damage to the optic nerve.
6. Is glaucoma surgery painful?
No. Most glaucoma surgery procedures are performed under local anaesthetic with sedation, meaning you are comfortable and relaxed throughout.
7. Can I drive with glaucoma?
Many people with glaucoma continue to drive. However, you must meet the DVLA standards for visual field and acuity, which is why effective eye pressure management is so important.
