Does interexaminer difference and the effect of training on the phenol red thread test result in Hong Kong-Chinese?
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.
Normal structures within the right atrium, such as the crista terminalis and Chiari network, may be seen more commonly with MRI than with other imaging modalities. An appreciation of the frequency with which these findings are seen should prevent inappropriate misdiagnosis of pathological masses when none is present.
