To determine the accuracy of manual compass measurement and trigonometric determination of proptosis (MCMATDP).
This agreement study included 120 eyes without eye diseases or injury of 60 patients who visited the ophthalmic clinic of Peking University Shenzhen Hospital from February 2020 to June 2020. The absolute values of proptosis were measured by MCMATDP and computed tomography (CT). The differences between the two methods were shown by Bland-Altman plot.
The cohort comprised 25 males and 35 females (average age 38.3 years). The absolute value of proptosis measured by CT was correlated with the MCMATDP. Further analysis showed that a 95% limit of agreement (LoA) was - 0.53 to 0.60 mm in the right eye and - 0.46 to 0.55 mm in the left eye between CT and MCMATDP. In addition, the 95% LoA was - 0.49 to 0.60 mm in both eyes between the two methods. All points were < 5% in Bland-Altman plots.
Compared to CT, MCMATDP is rather consistent in proptosis measurement. The new method is feasible in clinical practice when measuring proptosis. With the development of non-contact intelligent measurement software and the continuous improvement in measurement accuracy, a non-invasive, simple, and inexpensive measurement mode is true based on the theory of MCMATDP.
确定手动罗盘测量和三角测量眼球突出度（MCMATDP）的准确性。
本一致性研究纳入了2020年2月至2020年6月期间到北京大学深圳医院眼科门诊就诊的60例患者的120只无眼部疾病或损伤的眼睛。通过MCMATDP和计算机断层扫描（CT）测量眼球突出度的绝对值。两种方法之间的差异用Bland-Altman图表示。
该队列包括25名男性和35名女性（平均年龄38.3岁）。CT测量的眼球突出度绝对值与MCMATDP相关。进一步分析表明，CT与MCMATDP之间，右眼的95%一致性界限（LoA）为-0.53至0.60毫米，左眼为-0.46至0.55毫米。此外，两种方法之间双眼的95%LoA为-0.49至0.60毫米。Bland-Altman图中的所有点均<5%。
与CT相比，MCMATDP在眼球突出度测量方面相当一致。这种新方法在临床实践中测量眼球突出度时是可行的。随着非接触式智能测量软件的发展以及测量精度的不断提高，基于MCMATDP理论的无创、简单且廉价的测量模式成为现实。
