1.The retinal nerve fiber layer thickness in patients with nonarteritic anterior ischemic optic neuropathy was determined by optical coherence tomography. Its correlation with visual field defect was analyzed.
2.The retinal nerve fiber layer thickness from each optic disc quadrant was significantly increased in the acute stage, but significantly decreased in the resolving stage, in patients with nonarteritic anterior ischemic optic neuropathy.
3.In the acute stage, the thicker the retinal nerve fiber layer is, the worse the visual defects are. While in the resolving stage, the thinner the retinal nerve fiber layer is, the worse the visual defects are.
4.Optical coherence tomography is a useful diagnostic method for nonarteritic anterior ischemic optic neuropathy and can effectively evaluate the efficacy of treatment.
1.利用光学相干断层扫描定量测量非动脉炎性前部缺血性视神经病变患者视神经纤维层厚度,并对其与视野缺失之间的关系进行分析。
2.非动脉炎性前部缺血性视神经病变患者视神经盘各象限视神经纤维层厚度在急性期内明显增厚,而在恢复期明显变薄。
3.在非动脉炎性前部缺血性视神经病变急性期,视神经纤维层越厚,视野越差;而在恢复期视神经纤维层越薄,视野越差。
4.光学相干断层扫描可作为非动脉炎性前部缺血性视神经病变的诊断方法,并可对其治疗效果进行评价。
