AI System for Eye Diagnosis

Last updated on July 23rd, 2020 at 05:25 am

With the birth of the concept of Artificial Intelligence (AI), many new dimensions of innovations are coming up. AI controlled Eye Disease Detector is one of the best among them. The Moorfield Eye Hospital NHS Foundation Trust, DeepMind Health and UCL, has developed an AI system. This system can detect and make the correct recommended referral decision for more than 50 eye diseases. It works as accurately as an expert.

This research is published online by Nature Medicine. It describes the successful use of machine-learning technology trained on historic depersonalized eye scans to detect and identify the eye disease and also recommend the respective care to the patient.

Today, over 285 million people worldwide experience sight loss in one form or the other. One of the major cause of this is the various eye diseases.

The idea behind the AI system –

Researchers believe that this technology can transform the professional procedure of eye tests. Allowing early detection and also prioritize patients for the doctor’s referral. This may somewhat reduce the delay in proper treatment for the patients before it gets into a fatal stage.

Dr. Pearse Keane, consultant ophthalmologist at Moorfields Eye Hospital NHS Foundation Trust and NIHR Clinician Scientist at the UCL Institute of Ophthalmology said: “The number of eye scans we’re performing is growing at a pace much faster than human experts are able to interpret them. There is a risk that this may cause delays in the diagnosis and treatment of sight-threatening diseases, which can be devastating for patients.”

“The AI technology we’re developing is designed to prioritize patients. As those who need treatment urgently by a doctor or eye care professional. If we can diagnose and treat eye conditions early, it gives us the best chance of saving people’s sight. With further research, it could lead to greater consistency and quality of care for patients with eye problems in the future.”

Launched in 2016, the project brought together leading NHS eye health professionals and scientists from the National Institute for Health Research (NIHR) and UCL with some of the UK’s top technologists at DeepMind to figure out whether AI technology can contribute to improving the care of patients with sight-threatening diseases, for example, age-related macular degeneration and diabetic eye disease.

To check the results of the AI systems, the professional clinicians also viewed the same optical coherence tomography (OCT). The clinicians made their personal recommendations as per the OCT scans. The result of the AI system was matching with the clinicians’ recommendation to 94%. This is a really high figure supporting the efficiency and reliability of the system.

Two unique feature used of the AI system –

  • The system provides information to the professional clinicians explaining how it has arrived at its recommendations. And also the confidence percentage of its recommendations.This feature is valuable for the professionals to reflect upon the pieces of information before deciding on the type of diagnosis a patient requires.
  • The AI system is easily compatible with different types of eye scanner. This can increase the number of people who benefit from this technology significantly.

The next major challenge this AI system is to check through the clinical testings and prove its potential. Various hospitals and clinics are using this system as a demo trial. The AI system must prove itself effective and accurate to various clinical settings before gaining approval.

If the research successfully gains approval, it may bring a revolutionary change in the field of eye care diagnosis. This project will also speed up wider NHS research for many years to come. For example, significant resource investments to clean, curate and label Moorfields’ de-identified research data-set is made by DeepMind. This is to one of the most advanced eye research database of the world.
