The vitreous oxygen tension in the human vitreous body was measured using a polarographic oxygen electrode during vitreous surgery. To the best of the authors' knowledge, this is the first time these measurements have been taken in the human eye. The vitreous oxygen tensions in the anterior peripheral vitreous body, central vitreous body, and posterior vitreous body were 16.7 +/- 3.7 mmHg (mean +/- SD, n = 9), 15.9 +/- 2.8 mmHg and 19.9 +/- 4.8 mmHg, respectively. The preretinal oxygen tensions over the detached retina and detached macula were 30.0 +/- 4.8 mmHg (n = 5) and 15.3 +/- 2.1 mmHg (n = 3), respectively, with the latter significantly lower than the former (P less than 0.01). In one case, after inhalation of 100% oxygen the oxygen tension over the retinal scar resulting from cryoretinopexy in a previous retinal detachment surgery increased remarkably to 160 mmHg.
在玻璃体手术过程中，使用极谱氧电极测量了人玻璃体中的氧张力。据作者所知，这是首次在人眼中进行此类测量。周边前部玻璃体、中央玻璃体和后部玻璃体中的玻璃体氧张力分别为16.7±3.7 mmHg（平均值±标准差，n = 9）、15.9±2.8 mmHg和19.9±4.8 mmHg。脱离视网膜和脱离黄斑上方的视网膜前氧张力分别为30.0±4.8 mmHg（n = 5）和15.3±2.1 mmHg（n = 3），后者显著低于前者（P＜0.01）。在1例患者中，吸入100%氧气后，先前视网膜脱离手术中冷冻视网膜固定术所致视网膜瘢痕上方的氧张力显著升高至160 mmHg。
