Abnormal vitreal oxygen tension (pO2) has been implicated in a number of ocular and retinal diseases. We previously used MRI to non-invasively map pO2 of the human vitreous. In this study we improved spatiotemporal resolution using a modified Look-Locker sequence and improved surface coil and reported vitreous as well as anterior chamber pO2.
