目的评估不同级别白内障患者术前、术后视网膜血管血氧饱和度。方法本研究纳入40例1~3级老年性白内障患者40眼，全部40眼均接受标准超声乳化吸出人工晶状体植入术。在白内障手术前、手术后立即和手术后 3 个月，使用 Oxymap 系统测量平均视网膜动脉和静脉氧饱和度 (SO2) 水平。动静脉差（AVD）计算为动脉和静脉饱和度之间的差。进行线性回归分析以确定晶状体密度等级与测量的视网膜血管SO2变化之间的关系。结果受试者的平均年龄为64.17.8岁，其中14名（35%）为男性。视网膜小动脉中的平均 SO2 水平从术后立即的 90.5 +/- 7.8% 增加到 95.0 +/- 6.7%，并在术后 3 个月增加到 98.3 +/- 5.3%（p
PurposeTo assess the retinal vessel blood oxygen saturation preoperatively and postoperatively in patients with different grades of cataracts.MethodsThis study included 40 eyes from 40 patients with senile cataracts ranging from grade 1 to 3. All 40 eyes received standard phacoemulsification and intraocular lens implantation. The mean retinal arterial and venular oxygen saturation (SO2) levels were measured using the Oxymap system prior to, immediately after and 3months after cataract surgery. The arterial-venular difference (AVD) was calculated as the difference between the arterial and venular saturations. Linear regression analysis was performed to identify the relationship between the lens density grades and changes in the measured retina vessel SO2.ResultsThe mean age of the subjects was 64.17.8years, and 14 (35%) were male. The mean SO2 level increased in the retinal arterioles from 90.5 +/- 7.8% to 95.0 +/- 6.7% immediately postoperatively and to 98.3 +/- 5.3% at 3months after surgery (p
