A clear salt solution is gently pumped into the eye through one of the ports to maintain eye pressure during surgery and to replace the removed vitreous. The same instruments used during vitrectomy also may be used to remove scar tissue or to repair a detached retina. Vitrectomy may be performed as an outpatient procedure or as an inpatient procedure, usually requiring a single overnight stay in the hospital. After treatment, the eye may be covered with a patch for days to weeks and may be red and sore.

This research is being conducted in labs and clinical centers across the country. The network formed in and comprises more than physicians practicing at more than clinical sites across the country. Many of the sites are private practice eye clinics, enabling the network to quickly bring innovative treatments from research into community practice. NEI-funded scientists are also seeking ways to detect diabetic retinopathy at earlier stages. For example, researchers are harnessing a technology called adaptive optics AO to improve imaging techniques such as OCT.
