Wearable Diabetes Tech Access Could Save Thousands in NZ: Amputations and Vision Loss Averted
New Zealand’s wearable glucose tech roll-out promises major health gains In a landmark shift for diabetes care, New Zealand is expanding access to wearable glucose monitoring technology. Recent modelling data projects that thousands of diabetes-related amputations and vision loss could be prevented as more patients gain real-time insight into their blood sugar. The move is…

Computational Modeling Advances Retinogenesis: A Path to Regenerative Vision Therapies
New Computational Model Sheds Light on Retinogenesis A pioneering computer model developed by researchers at the University of Surrey is providing a detailed look at the stages of retinogenesis — the process by which the retina forms and regenerates. This first-of-its-kind model can simulate how retinal cells develop, interact, and respond to injury, offering a…

Valsalva Retinopathy: Vision Loss After Lifting Weights
What is Valsalva Retinopathy? Valsalva retinopathy is a rare but important eye condition caused by a sudden rise in pressure in the chest and abdomen. This pressure surge can force tiny blood vessels in the retina to rupture, leading to a preretinal or intraretinal hemorrhage that temporarily blurs or blocks vision. The event is typically…

Valsalva Retinopathy from Weightlifting: What It Means
Understanding the case: Sudden vision loss after weightlifting A recent case drew attention after a 26-year-old man experienced a rapid, painless loss of vision in one eye during heavy weightlifting at the gym. Initial exams showed dense pre-retinal and vitreous hemorrhage, leading clinicians to diagnose Valsalva Retinopathy. This condition, while uncommon, highlights how intense physical…

Six in Ten Diabetics Do Not Get Vision-Saving Eye Exams
Why Diabetes Eye Exams Matter Diabetes increases the risk of several serious eye diseases and vision loss. Even people who manage blood sugar well can develop diabetic retinopathy, glaucoma, or cataracts at higher rates than non-diabetics. Medical groups advocate for a dilated eye exam each year so an ophthalmologist can detect early changes before vision…
