First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compared two ways to control pain during laser treatment for diabetic retinopathy: a numbing injection around the eye versus standard numbing eye drops. Fifty adults with diabetes were split into two groups to receive either the injection or a sham injection with drops. Researchers measured pain levels and vital signs during the procedure to see which method worked better.
