Comparative Study
Interexaminer difference and the effect of training on the phenol red thread test results in Hong Kong-Chinese.
This study evaluated interexaminer agreement in the measurement of tear volume using the phenol red thread (PRT) test on Hong Kong-Chinese subjects. The effect of an intensive training session on interexaminer agreement was also investigated. ⋯ Our results suggest that the interexaminer agreement of PRT results is influenced by both examiner- and training-specific factors. Intensive training is important for ensuring the highest consistency among examiners. The moderate interexaminer agreement suggests that clinicians should seek a substantial difference in tear volume when making decisions regarding interventions for their Hong Kong-Chinese patients.
