Common vergence disorders, characterized by instability between a subject’s eyes as they try to focus on an object (convergence and divergence), can be diagnosed by examining the horizontal fusional reserves of the eye. This study looks at “Infrared eyetracking technology [which] shows promise for obtaining automated and objective measurements of fusional reserves.” This paper is the result of an international collaboration with the University of Auckland, New Zealand.
