AIM
The aim of this study was to evaluate the diagnostic performance of strain ratio elastography in the assessment of retrobulbar orbital fat tissue.
MATERIALS AND METHODS
The retrobulbar fat tissue of 14 eyes in 14 participants was scanned by sonoelastography. All the participants had permanent vision loss secondary to glaucoma in at least one eye. The elasticity scores were determined and the strain ratio was based on the comparison of the average strain measured in the retrobulbar fat tissue around the optic nerve at the same depth.
RESULTS
The mean strain values for the optic nerve (B) and the retrobulbar fat tissue (A) were 0.78+/-0.61 and 1.43+/-0.99, respectively (p=0.005). The mean strain ratio (B/A) was 0.56+/-0.24.
CONCLUSION
This preliminary study showed that by providing strain values and ratios of different orbital tissues sonoelastography may have a potential use in the diagnosis and follow-up of orbital inflammatory and infiltrative diseases.
目的
本研究旨在评估应变率弹性成像在评估球后眶脂肪组织中的诊断性能。
材料与方法
对14名参与者的14只眼睛的球后脂肪组织进行超声弹性成像扫描。所有参与者至少有一只眼睛因青光眼导致永久性视力丧失。确定弹性评分，应变率基于在相同深度视神经周围球后脂肪组织中测量的平均应变的比较。
结果
视神经（B）和球后脂肪组织（A）的平均应变值分别为0.78±0.61和1.43±0.99（p = 0.005）。平均应变率（B/A）为0.56±0.24。
结论
这项初步研究表明，通过提供不同眼眶组织的应变值和比率，超声弹性成像可能在眼眶炎性和浸润性疾病的诊断和随访中具有潜在用途。
