The AI algorithm that can detect glaucomatous damage in retinal scans
How useful would it be to have a test capable of picking up signs of glaucoma even 18 months earlier than with current methods, such as OCT? A new way of visualizing retinal cells, called DARC (Detection-of-Apoptosing-Retinal-Cells), developed as part of a clinical trial sponsored by the UCL Institute of Ophthalmology in London, UK, uses a fluorescent dye to illuminate cells in the process of apoptosis.
Then, an AI-aided algorithm analyzes patients’ retinal scans and refers those with higher DARC counts for further diagnosis. The trial found a significantly raised DARC number in patients who later progressed. The new method could also be used to test patients with AMD, as well as other neurodegenerative diseases.

Having edited several technical publications over the last decade, I crossed paths with quite a few of Texere's current team members, and I only ever heard them sing the company's praises. When an opportunity arose to join Texere, I jumped at the chance! With a background in literature, I love the company's ethos of producing genuinely engaging content, and the fact that it is so well received by our readers makes it even more rewarding.
