Reliability and variability in the measurement of interlimbal distance with a semiautomated video replay analysis system (SAVRAS).
This paper reports on the reliability and variability of a semi-automated, video replay and analysis system (SAVRAS) in determining interlimbal distance in patients with strabismus. Factors under investigation were: choice of observer, choice of video frame, patient age and patient state (awake or anesthetized). It was demonstrated that SAVRAS was a highly reliable and reproducible system. This system is currently in use to evaluate the relationship between the succinylcholine induced ocular position, under anesthesia, and the postoperative awake alignment.
