To measure the transcorneal dispersion of oxygen into the anterior chamber, dynamic T1‐weighted fast‐spin‐echo MRI (TR = 2 seconds, TE = 15 msec, 5‐mm slice) of the human eye was performed both before and during oxygen supply to a full goggle placed on the face. During the course of the imaging, a significant increase in the signals in the anterior chamber occurred. This indicated that transcorneal dispersion of oxygen into the anterior chamber can be evaluated by this procedure, suggesting that this method may be useful for diagnosing dysfunction of the cornea or aqueous flow.
