. To evaluate the oxygen saturation in retinal blood vessels in patients after closed-globe blunt ocular trauma. . Retrospective observational case series. . Retinal oximetry was performed in both eyes of 29 patients with unilateral closed-globe blunt ocular trauma. Arterial oxygen saturation (SaO), venous oxygen saturation (SvO), arteriovenous difference in oxygen saturation (SO), arteriolar diameter, venular diameter, and arteriovenous difference in diameter were measured. Association parameters including age, finger pulse oximetry, systolic pressure, diastolic pressure, and heart rate were analyzed. . The mean SaO in traumatic eyes (98.1% ± 6.8%) was not significantly different from SaO in unaffected ones (95.3% ± 7.2%) ( = 0.136). Mean SvO in traumatic eyes (57.1% ± 10.6%) was significantly lower than in unaffected ones (62.3% ± 8.4%) ( = 0.044). The arteriovenous difference in SO in traumatic eyes (41.0% ± 11.2%) was significantly larger than in unaffected ones (33.0% ± 6.9%) ( = 0.002). No significant difference was observed between traumatic eyes and unaffected ones in arteriolar ( = 0.249) and venular diameter ( = 0.972) as well as arteriovenous difference in diameter ( = 0.275). . Oxygen consumption is increased in eyes after cgBOT, associated with lower SvO and enlarged arteriovenous difference in SO but not with changes in diameter of retinal vessels.
评估闭合性眼球钝挫伤患者视网膜血管中的氧饱和度。
回顾性观察病例系列。
对29名单侧闭合性眼球钝挫伤患者的双眼进行视网膜血氧测定。测量动脉血氧饱和度（SaO）、静脉血氧饱和度（SvO）、血氧饱和度动静脉差值（SO）、小动脉直径、小静脉直径以及直径动静脉差值。分析包括年龄、手指脉搏血氧饱和度、收缩压、舒张压和心率在内的相关参数。
患眼的平均SaO（98.1%±6.8%）与未受影响眼的SaO（95.3%±7.2%）无显著差异（P = 0.136）。患眼的平均SvO（57.1%±10.6%）显著低于未受影响眼（62.3%±8.4%）（P = 0.044）。患眼的SO动静脉差值（41.0%±11.2%）显著大于未受影响眼（33.0%±6.9%）（P = 0.002）。患眼与未受影响眼在小动脉直径（P = 0.249）、小静脉直径（P = 0.972）以及直径动静脉差值（P = 0.275）方面未观察到显著差异。
闭合性眼球钝挫伤后患眼的氧消耗增加，与较低的SvO和增大的SO动静脉差值相关，但与视网膜血管直径变化无关。
