Abstract

1. Abstract:

1.1. Background: To explore the accuracy of trigonometric function in proptosis measurement.

1.2. Methods: It was a none-inferiority trial. In our research, 120 eyes of 60 patients without eye diseases or injury were included. The patients came to our clinic from February, 2020 to June, 2020. The absolute values of proptosis were measured by trigonometric function and computed tomography.
