目的:研究高压氧治疗与药物治疗本病后视网膜血液循环状态及影响因素的变化。方法:对诊断明确后的100例患者进行眼底血管造影。记录臂—视网膜循环时间(A-RCT),视网膜静脉充盈时间(RVFT),测定血浆纤维蛋白元(FIB)含量、血浆粘度(D)、红细胞压积(HCT),阻塞血管无灌区位置(VOP),动脉硬化压迫状态(AP),根据病人经济条件,给予同类的溶栓或扩血管药物治疗。然后将患者随机分为药物治疗组和高压氧(HBO)治疗组。2组分别治疗一个标准疗程后复查上述项目。并对2组治疗前后参数进行统计学处理后进行比较、分析、讨论。结果:HBO对静脉阻塞点位置和动脉压迫状态有明显作用。结论:高压氧对静脉阻塞点位置和动脉压迫状态有显著意义,对毛细血管无血灌注区有确切疗效,视力恢复明显。
Objective: To study the changes of retinal blood circulation and its influencing factors after hyperbaric oxygen therapy and drug therapy. Methods: The fundus angiography was performed on 100 patients with definite diagnosis. Recording arm-retinal circulation time (A-RCT), retinal vein filling time (RVFT), determination of plasma FIB, plasma viscosity (D), hematocrit (HCT) ), Atherosclerosis state of oppression (AP), according to the patient’s economic conditions, to give similar thrombolytic or vasodilator drug treatment. Patients were then randomized into a drug-treated group and a hyperbaric oxygen (HBO) -treated group. 2 groups were treated after a standard course of treatment to review the above items. The parameters of two groups before and after treatment were statistically analyzed and compared, analyzed and discussed. Results: HBO had a significant effect on venous occlusion location and arterial compression state. CONCLUSION: Hyperbaric oxygen has significant effect on venous occlusion location and arterial compression state, and has definite curative effect on capillary bloodless perfusion area and obvious visual acuity recovery.
