Google eye AI tops one million patients in three countries
TL;DR
- A Google diabetic retinopathy AI model has now screened over a million patients across health systems in India, Thailand and Australia.
- The deployment spans Aravind Eye Care System in Madurai, Rajavithi Hospital in Bangkok, and Lions Outback Vision in Western Australia.
- It is a lessons-learned Comment in Nature Medicine, published 23 September 2026, co-authored by Google researchers and clinicians at each deploying site.
Over one million patients have now been screened by a Google diabetic retinopathy AI model deployed across India, Thailand and Australia, according to a Comment published in Nature Medicine on 23 September.
The three anchor sites are the Aravind Eye Care System in Madurai, Rajavithi Hospital in Bangkok, and Lions Outback Vision at the Lions Eye Institute in Western Australia. The lead authors, Richa Tiwari, Rajroshan Sawhney and Kasumi Widner of Google, write with clinical co-authors from each deploying site that the deployment "offers cross-cutting insights that may inform the expansion of healthcare artificial intelligence globally."
Two researchers we track flagged the paper the day it ran.
It is a lessons-learned Comment, not a trial report. The retrieved passage carries no fresh per-site accuracy or false-negative numbers; those will live in the full text or in the earlier evaluations this piece builds on.
