Treatment with norrin helps maintain healthy blood vessels and preserve vision in diabetic rats

AI Summary

Researchers report that treatment with norrin helped preserve retinal blood vessels and vision in diabetic rats. The findings may inform future research into diabetic retinopathy, a complication that can cause vision loss or blindness in people with poorly managed diabetes.

Millions of people in the U.S. are affected by diabetic retinopathy, a complication of diabetes that affects the eyes. The condition is caused by damage to the blood vessels in the retina, the light-sensitive tissue at the back of the eye. At first, diabetic retinopathy might not cause any symptoms, or the problems might be mild. However, if the underlying diabetes remains poorly managed, it can lead to blindness.
