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.
