Clinical Significance of Retroocular Artery Hemodynamics and Optic Nerve Diameter in Patients with Type 2 Diabetes Mellitus with Nonproliferative Macular Edema by Ultrasonography
Objective:To investigate the utility of ultrasonography in evaluating the hemodynamics of the retroocular artery and optic nerve diameter in nonproliferative macular edema(ME)patients with type 2 diabetes mellitus(T2DM).Methods:The optical coherence tomography(OCT)results of 74 T2DM patients admitted to the hospital from September 2020 to September 2021 were retrospectively analyzed,and the patients were divided into 2 groups according to the examination results.36 patients with T2DM in non-proliferative stage were divided into the control group,and the 38 nonproliferative ME patients with T2DM were divided into the observation group.The hemodynamic parameters[maximum systolic blood flow velocity(PSV),end-diastolic blood flow velocity(EDV),resistance index(RI)],and retrobulbar optic nerve diameter were compared.Results:The PSV,EDV and RI of CRA in the observation group were lower than those in the control group,with statistically significant difference(t=14.450,10.584,2.124;P＜0.05).PSV and EDV of PCA in the observation group were lower than those in the control group,and there was statistical difference(t=3.937,6.929;P＜0.05).The diameter of the posterior optic nerve was(2.71±0.36)mm in the control group and(2.65±0.31)mm in the observation group,with no statistical difference(t=0.770,P＞0.05).Conclusion:Ultrasound can effectively monitor the retroocular artery hemodynamics and optic nerve diameter in non-proliferative ME patients with T2DM,which can provide a reliable basis for early clinical treatment and has high clinical application value.
