Modern ophthalmology has transformed the way we see and protect vision, thanks to revolutionary technologies like the Angio OCT eye test. At Blue Fin Vision® Eye Clinic, our commitment to excellence means employing the latest in eye diagnostics to offer comprehensive, individualised care. Whether you seek routine eye assessments or are considering advanced vision correction surgery, understanding tests like Angio OCT will reassure you of our expertise and dedication.
What is an Angio OCT Eye Test?
The Angio OCT eye test, also known as optical coherence tomography angiography (OCTA), is a cutting-edge, non-invasive diagnostic test. It delivers highly detailed three-dimensional images of the retina’s blood vessels and microcirculation without the need for injectable dyes. The Angio OCT utilises a safe, infrared light to scan various layers of the retina and the underlying choroid, mapping out even the tiniest blood vessels with micrometric precision. This has greatly improved the early detection and monitoring of eye conditions compared with previous techniques that required contrast agent injections.
What is an Angio OCT?
An Angio OCT is an advanced form of OCT technology, offering unprecedented insights into the vascular structure of the eye. By capturing precise, cross-sectional views of the eye’s circulation, Angio OCT enables our specialists to visualise and assess blood flow through the retina, choroid, and optic nerve head. This allows the identification of even subtle changes or abnormalities that might otherwise go unnoticed, empowering early diagnosis and better management of vision-threatening diseases.
Why Do I Need an Angio OCT of My Eye?
You may be recommended an Angio OCT for various reasons, including:
- Unexplained vision changes: To investigate symptoms such as blurred or distorted vision, unusual spots, or reduced clarity.
- Detection and monitoring of retinal diseases: Essential for conditions like age-related macular degeneration (AMD), diabetic retinopathy, retinal vascular occlusions, and macular oedema.
- Glaucoma assessment: Evaluating the vascular component and structure of the optic nerve head in glaucoma.
- Pre- and post-operative assessments: Guiding eye surgery planning and monitoring healing and outcomes.
- Ongoing care for at-risk patients: If you have diabetes or a family history of retinal conditions, regular Angio OCT scans can spot problems before symptoms start.
Blue Fin Vision®’s top-rated eye assessments help safeguard your eyesight by enabling early detection and prompt treatment. Our leading surgeons, top specialists, and top doctors use this tool to refine diagnoses and tailor care uniquely for you.
What Does an Angio OCT Eye Test Show?
An Angio OCT eye test produces rich, layered images revealing:
- The arrangement and integrity of blood vessels within and beneath the retina.
- Patches of poor or abnormal blood flow that may indicate disease.
- Early vascular changes, microaneurysms, or leakage undetectable with standard eye tests.
- The effects of treatments or progression of eye conditions over time.
This precise data is invaluable for diagnosing and managing a broad range of conditions, from AMD and diabetic retinopathy to retinal vein occlusion and glaucoma. The detail offered by Angio OCT supports proactive care and the best possible visual outcomes.
What to Expect from an Angio OCT Eye Test
When visiting Blue Fin Vision® Eye Clinic – whether in London (Harley Street, Weymouth Street), Chelmsford, or Hatfield – you can be assured your comfort is our priority:
- The procedure is completely painless and non-contact; there is no need for needle injections or pupil dilatation in most cases.
- You will sit at the machine and focus on a small target whilst the scan takes place. Your eye does not come into contact with the device, and you may see a light but will feel nothing.
- The scan itself typically lasts less than five minutes per eye.
- No special preparation is needed; unless otherwise advised, you may drive and continue daily activities as normal after your appointment.
- Immediate results: The images are available straight away, allowing our top specialists to discuss findings and next steps with you during your visit.
Our clinics blend advanced technology with a warm, professional approach, ensuring your experience is reassuring and informative every step of the way.
How Long Does an Angio OCT Eye Test Take?
The Angio OCT scan is remarkably efficient. The full process, including patient setup and discussion of findings, is usually completed within fifteen to twenty minutes. The actual scanning for each eye takes only around five minutes, with the rest of your appointment focused on explanation and personalised advice from our clinical team.
