Plugging leaky blood vessels to save vision

A new drug approach has been developed for safer clean-up of deformed blood vessels in the eye. The growth of malformed blood vessels that can burst is a leading cause of vision loss in North America. Retinopathy and retina degeneration are associated with premature birth, with diabetes, and with increasing age. This research shows both safety and effectiveness in their bioengineered compound when treating retinopathy in mice.
