Comparison of Dissociated Phoria Measuring Methods. Repeatability and Reliability

BACKGROUND
Many methods of heterophoria measurement are clinically available. Several studies have been carried out to compare their results. Due to the difference of the methods in the ability to control accommodation, the induced proximal convergence, the technique used for dissociation, and the method of data analysis1, the results can vary on the same patient.

The aim of this study is to determine the reliability and compare reproducibility of different dissociated phoria measure tests: Modified Thorington, Von Graefe, and “fast” and “slow” Cover Test. For that purpose, I designed a specific protocol, in order to control and equate test conditions.
