Rox is an oxygen delivery platform where oxygen is encapsulated in a nanoparticle or nanobubble. Rox delivers oxygen to retinal tissues in need when hypoxic conditions threaten the health of cells in the retinal layers. The technology is being developed to treat Central Retinal Artery Occlusion (CRAO), which is a stroke-like condition of the retina that leads to irreversible blindness. No therapy currently exists to treat this condition.
