The agreement of the nomogram tool and UBM images in calculating UCP probe model in Chinese patients.

The agreement between UBM images and the nomogram tool to calculate the UCP probe model of Chinese patients is at a fair level. The nomogram tool prefers to use larger probes. Improvements to the nomogram tool, such as including data from more ethnic groups and being able to calculate separately for different types of glaucoma, are needed to improve accuracy. The inclusion of parameters or images from more directions of the eye may help to measure probe models more accurately for both the nomogram tool and the UBM image measurement.
