Early Detection of Glaucoma with OCT, Optomap & Next-Gen VR Visual Fields

Nish Fofaria • 22 October 2025

Why catching glaucoma early matters

Glaucoma is a group of eye conditions that damage the optic nerve, often linked to pressure inside the eye. It usually has no symptoms in the early stages—no pain, no blur—so people can lose vision slowly without noticing. The good news: early detection and treatment can preserve sight.

At Eyecare Opticians in Ham, we combine three advanced technologies to spot glaucoma sooner and monitor it more precisely:
- REVO OCT (Optical Coherence Tomography) – high-resolution 3D scans of the optic nerve and retinal nerve fibre layer.
- Optomap – ultra-widefield retinal imaging that captures up to 200° of the retina in one shot.
- VR visual field testing using a headset (Pico Neo 3 Pro) – comfortable, portable assessment of your peripheral vision.

Together, these tools give us a 360° view of your eye health — structure, function, and wide-angle context.


REVO OCT: Microscopic detail in seconds

OCT uses safe light waves to create cross-sectional images of the retina and optic nerve head. We can:
- Measure the retinal nerve fibre layer (RNFL) and ganglion cell complex (GCC) thickness.
- Detect subtle thinning long before it’s visible on routine examination.
- Track change over time with like-for-like comparisons and progression analysis.

Why it matters: Glaucoma damages nerve tissue. OCT quantifies that tissue so we can act before visual symptoms appear.


Optomap: Ultra-widefield clarity

Traditional images capture only a small portion of the retina. Optomap takes an ultra-wide view, letting us:
- See the optic nerve and surrounding retina in context.
- Identify other issues that can mimic or complicate glaucoma (e.g., haemorrhages, pigment changes).
- Build a visual record for side-by-side reviews at future checks.

Why it matters: A wider retinal view helps us avoid blind spots in diagnosis and provides crucial context for OCT findings.


VR Visual Field Testing (with Pico Neo 3 Pro): Your side vision, reimagined

Visual field testing checks how far and how well you can see out to the sides—the functional impact of glaucoma. Using a comfortable VR headset, we can:
- Run standardised perimetry in a more natural, patient-friendly setup.
- Reduce fatigue and improve concentration for more reliable results.
- Test in different positions and environments, supporting consistent monitoring.

Why it matters: Glaucoma typically affects peripheral vision first. Reliable visual fields help confirm diagnosis and track functional change over time.


What to expect at your glaucoma screening

1. History & risk check
2. Eye pressure & corneal thickness
3. REVO OCT scan
4. Optomap image
5. VR visual field test
6. Same-day explanation

We’ll show you the images and graphs, explain any risk, and provide a clear plan—reassurance, monitoring, or referral if needed.


Who should book a glaucoma check?

• Age 40+
• Family history of glaucoma
• Higher eye pressure readings
• Short- or long-sightedness, migraine/vascular issues, or sleep apnoea
• African, Afro-Caribbean or Asian ancestry
• Anyone noticing haloes, headaches, or blurred peripheral vision

In England, many people at risk qualify for NHS sight tests; ask us what applies to you.


Why choose Eyecare Opticians (Ham, Kingston upon Thames)?

After examining more than 20,000 eyes over the past 20 years, certain patterns start to emerge. Patients often come in believing their vision is fine or that eye tests are simply about updating glasses. In reality, modern eye examinations have evolved dramatically since I first started practising. Thanks to significant investment in advanced technology, today’s eye examinations allow us to detect eye disease earlier and more accurately than ever before. Here are seven things many people misunderstand about their vision. 1. “My vision is fine, I don’t need an eye test.” Vision usually deteriorates very gradually. Most patients only realise how much their eyesight has changed when they put on their new glasses and suddenly see the world more clearly. Regular eye examinations are essential because changes can occur slowly without you noticing. 2. Eye Tests Are Not Just About Glasses Your eyes can reveal much more than your prescription. During a comprehensive eye examination we can sometimes detect early signs of conditions such as: Diabetes High blood pressure High cholesterol Neurological issues The eye is the only place in the body where we can directly observe blood vessels and nerves non-invasively. 3. Myopia in Children Is Increasing One of the biggest changes I have seen in practice is the rise in myopia (short-sightedness) in children. Modern lifestyles mean children spend more time indoors and on digital devices. Research shows that encouraging children to spend more time outdoors can reduce the risk of developing myopia. The encouraging news is that we can now slow the progression of myopia by around 50% over an eight-year period. Treatment options include: Orthokeratology (Ortho-K) – specially designed contact lenses worn overnight to gently reshape the cornea Specialist myopia control spectacle lenses designed to slow the growth of the eye Early intervention can significantly reduce the risk of eye disease later in life. 4. Many Serious Eye Conditions Have No Early Symptoms Many people assume they would notice if something was wrong with their eyes. Unfortunately, this is not always the case. Conditions such as glaucoma and macular degeneration often develop silently without symptoms in the early stages. This is why regular eye examinations are so important. 5. Technology Has Transformed Eye Examinations When I first started practising, we did not have access to the level of diagnostic technology we use today. With Optical Coherence Tomography (OCT), we can now examine the layers of the retina in extraordinary detail. This allows us to detect early signs of conditions such as: Glaucoma Age-related macular degeneration (ARMD) Retinal disease Often years before symptoms appear. 6. We Can See More of the Retina Than Ever Before Using Optomap widefield imaging, we can examine a much larger area of the retina compared with traditional methods. This means we can sometimes detect: Retinal holes Retinal tears Peripheral retinal changes Many patients have no symptoms at all, but identifying these problems early can prevent serious complications. 7. Early Detection Really Is Better Than Cure Perhaps the most important lesson from two decades of examining eyes is this: Early detection saves sight. Modern eye examinations are no longer simply about vision correction. They are about protecting eye health for the long term. Regular eye tests allow us to detect problems early and ensure the best possible outcome for our patients. Final Thoughts After examining thousands of eyes, one thing is clear: Looking after your eyes today helps protect your vision for the future. If it has been a while since your last eye examination, it may be time to book one. Your eyes may be telling a story you haven’t yet noticed.  📍 Eyecare Opticians Kingston upon Thames
