Summary

Story summary

Researchers at the University of Coimbra used optical coherence tomography to detect retinal changes in rats with type 2 diabetes before retinopathy becomes visible.
The findings suggest eye scans may predict vision loss in diabetics by identifying early retinal texture changes.
The approach could enable earlier diagnosis and treatment, potentially improving patient outcomes.
The study notes potential for AI tools to detect these changes, but further human research is needed.
