AI technology can detect anaemia in elderly patients through simple eye examination

A remarkable medical innovation could transform the way anaemia is detected in older people. Researchers have developed an artificial intelligence system that can identify red blood cell deficiency simply by analysing the eyes, eliminating the need for painful venous punctures.

The technology uses short 10-second video recordings of the eyes to accurately estimate blood haemoglobin levels. During tests conducted on 224 participants, the system successfully identified anaemia in over 80% of cases, demonstrating promising potential for senior care.

Benefits for monitoring older adults

For older people, this technology could represent a true revolution in health monitoring. Dr Christine Kiire, an ophthalmology specialist, explains that its primary value lies in facilitating frequent, non-invasive monitoring — a crucial consideration for seniors who require regular check-ups.

The system would be particularly valuable for elderly patients undergoing cancer treatment, those requiring dialysis, or patients with chronic conditions that necessitate repeated blood tests. Eliminating the discomfort and stress associated with frequent blood draws could significantly improve the quality of life for these patients.

Accessible and accurate technology

The analysis process is surprisingly straightforward. A specialised camera records short videos of the whites of the eyes, and a programme called Video-to-Vessels processes the images by removing interference. An AI model then analyses blood circulation in the ocular vessels to predict haemoglobin levels.

Perhaps most promisingly, the technology could be adapted for use with smartphones, making it accessible even in care homes or for home-based care. This would allow regular health monitoring without the need for frequent trips to the laboratory.

Limitations and future prospects

Although the results are encouraging, specialists caution that the technology is not yet ready to fully replace standard blood tests. The system could work excellently as an initial screening tool, identifying older adults who require further investigation.

Dr Peter Campbell, an ophthalmology specialist, believes that many stages remain before the technology will be available for clinical use. Nevertheless, its potential for improving elderly care is clear, offering a gentler method of health monitoring for this vulnerable group of patients.
