Robots in your eyes

Retinal vein occlusion from glaucoma is only one of several diseases that can decrease the oxygen supply to the retina: Like every tissue of our body the retina needs oxygen. An insufficient supply can cause blindness, sometimes within mere hours. In order to make a fast and correct diagnosis, physicians need to be able to assess oxygen levels within the eye. However, the currently available tools are not very sensitive. Researchers of the multi-scale robotics lab at ETH Zürich have now developed a micro-robot that can measure the retina’s oxygen supply.
