Hidden Early Signs of Diabetic Blindness Revealed

Scientists have developed a powerful new imaging method that reveals how immune cells in the eye behave long before visible damage occurs in diabetic retinopathy. Using a combination of a head-fixation device, contact lenses, and a custom objective lens, researchers were able to capture live, high-resolution images of microglia activity in diabetic mice.

Low Blood Sugar Triggers Retinal Damage, Vision Loss

New research reveals that hypoglycemia may worsen diabetic retinopathy by breaking down the blood-retinal barrier. In diabetic mice, low blood sugar increased levels of hypoxia-inducible factor (HIF), a protein linked to abnormal blood vessel growth and leakage.

Uncovering the Key Process That Contributes to Vision Loss and Blindness in People With Diabetes

The loss of blood flow autoregulation caused by diabetes is the result of the disruption of the TRPV2 protein. Even in the absence of diabetes, disrupted blood flow autoregulation causes damage closely resembling that seen in diabetic retinopathy.
