PURPOSE: To report vitreous oxygen tension before, immediately after, and at longer times after vitrectomy.DESIGN: A prospective, interventional consecutive case series.METHODS: Oxygen was measured using an optical oxygen sensor in patients undergoing vitrectomy. Intraoperatively, oxygen measurements were taken before and after vitrectomy in two intraocular locations: adjacent to the lens and in the mid-vitreous.RESULTS: Sixty-nine eyes underwent oxygen tension measurements at the time of vitrectomy. In baseline eyes, oxygen tension in the vitreous was low, measuring 8.7 +/- 0.6 mm Hg adjacent to the lens and 7.1 +/- 0.5 mm Hg in the mid,vitreous. The difference between the two locations was statistically significant (P
