Preserving lifelong vision begins with precision in diagnosis and the highest standards of clinical care. At Blue Fin Vision® Eye Clinic, our expert team combines advanced diagnostic technology with a deeply personalised approach to keratoconus screening and management. We are committed to staying at the forefront of ophthalmic innovation for the benefit of every patient who entrusts us with their eye health.
Understanding Keratoconus: A Modern Ophthalmology Challenge
Keratoconus is a progressive eye condition where the normally round cornea becomes thin and develops a cone-like bulge. This can cause blurred and distorted vision, increasing astigmatism, and increased sensitivity to light. Early and accurate detection of keratoconus is essential in guiding treatment, halting progression, and preserving quality of life.
Blue Fin Vision® is proud to offer patients access to the best in keratoconus diagnostics, from initial eye assessments to bespoke management plans delivered by top doctors, top specialists, and leading surgeons. Our clinics on Harley Street and Weymouth Street in London, as well as in Chelmsford and Hatfield, are equipped with cutting-edge tools to provide accurate, rapid diagnosis in a caring, professional environment.
What is Epithelial Mapping?
Epithelial mapping is a breakthrough technique in the diagnosis and ongoing care of keratoconus and other corneal diseases. Epithelial thickness mapping uses high-resolution imaging to measure the layer of epithelial cells covering the cornea. Because these cells can respond to underlying structural changes, mapping their distribution can reveal very early or subtle changes associated with keratoconus before they become apparent with standard topography.
Crucially, at Blue Fin Vision® Eye Clinic, we use epithelial mapping for all our laser eye surgeries. This meticulous approach ensures that we do not miss cases of forme fruste keratoconus – a very early or subclinical form of the condition. By integrating epithelial mapping into our protocol, we maximise patient safety and provide peace of mind before any vision correction procedure.
Benefits of Epithelial Mapping
- Detecting keratoconus at its earliest stages, even before visual symptoms develop.
- Distinguishing early keratoconus from normal or borderline corneal variations.
- Monitoring response to keratoconus treatments, such as corneal cross-linking.
- Enhancing safety for patients considering vision correction surgery, such as LASIK, by screening out unsuitable candidates.
- Supporting the most accurate and tailored management plans for each patient.
At Blue Fin Vision® Eye Clinic, our advanced epithelial mapping technology is managed by experienced professionals, ensuring every scan is expertly analysed and explained in clear, accessible terms.
What is the Belin/Ambrosio Score?
The Belin/Ambrosio Enhanced Ectasia Display, often referred to as the Belin/Ambrosio score, is a sophisticated, algorithm-driven tool used to evaluate the risk of corneal ectasia, most commonly keratoconus.
This analysis integrates various data sources, such as corneal thickness, shape, and topographical irregularities, to generate a comprehensive risk assessment. The Belin/Ambrosio score is particularly valuable in:
- Identifying early or mild forms of keratoconus that traditional eye tests may miss.
- Assessing candidacy for vision correction surgery or suitability for corneal cross-linking.
- Providing objective guidance for treatment planning, allowing your specialist to tailor interventions to your eyes’ unique structure.
Trusting your care to Blue Fin Vision® means benefiting from the latest evidence-based screening, guided by top specialists who interpret these scores in the full context of your visual health and aspirations.
Why is Advanced Keratoconus Screening Essential?
Keratoconus can progress slowly and may remain undetected during routine eye tests. Professional eye assessments, enhanced by epithelial mapping and Belin/Ambrosio analysis, provide a clear, reliable foundation for:
- Early intervention: Timely diagnosis can delay or prevent progression, safeguarding long-term vision.
- Personalised treatment: Tailored treatments, including contact lenses, cross-linking, and vision correction surgery, depend on detailed corneal mapping.
- Surgical safety: Screening minimises the risk of complications if surgery is needed later.
Leading surgeons at Blue Fin Vision® know that a single missed diagnosis can make the difference between sustained clarity and permanent visual loss. This is why we prioritise the most advanced diagnostic protocols for every patient.
