Cambs Uni study suggests AI effective at assessing eye problems

A University of Cambridge study has suggested Artificial Intelligence model ChatGPT could be better at assessing eye problems than doctors.
The technology could be deployed to triage patients and determine who needs specialist care and who can wait to see a GP.
Academics from the University tested the ability of ChatGPT 4 against the knowledge of medics at various stages of their careers, including junior doctors and eye specialists in training.
374 ophthalmology questions were used to train the language model, with its accuracy then tested in a mock exam of 87 questions.
It's answers were compared to those from five expert ophthalmologists, three trainee ophthalmologists, and two unspecialised junior doctors, as well as an earlier version of ChatGPT and other language models Llama and Palm2.
Researchers said language models like ChatGPT are approaching "expert-level performance in advanced ophthalmology questions".
Lead author of the study Dr Arun Thirunavukarasu, who carried out the work while studying at the University of Cambridge's School of Clinical Medicine, said:
"We could realistically deploy AI in triaging patients with eye issues to decide which cases are emergencies and need to be seen by a specialist immediately, which can be seen by a GP, and which don't need treatment."
"The models could follow clear algorithms already in use, and we've found that ChatGPT-4 is as good as expert clinicians at processing eye symptoms and signs to answer more complicated questions.
"With further development, large language models could also advise GPs who are struggling to get prompt advice from eye doctors.
"People in the UK are waiting longer than ever for eye care."
Researchers said that while language models "do not appear capable" of replacing eye doctors, they could "provide useful advice and assistance to non-specialists".
Dr Thirunavukarasu, who now works at Oxford University Hospitals NHS Foundation Trust, added: "Even taking the future use of AI into account, I think doctors will continue to be in charge of patient care."
"The most important thing is to empower patients to decide whether they want computer systems to be involved or not. That will be an individual decision for each patient to make."
