[Critical study of dissociated dyssynergia].
Results of an electro-oculographic study in 123 cases of esotropia emphasized the important role of the angle of deviation in the appearance of dissociated dyssynergia, as this phenomenon was present in all cases with a greater than 30 degree angle convergent strabismus. Small angle esotropia alone produces dyssynergic tracings interpretable as arising from a blocking syndrome. Furthermore, a new method for measuring dyssynergia was found to possess certain advantages, the position of the electrodes in relation to the globe, particularly when it is deviated, being of primary importance to obtain satisfactory tracings. This problem can be avoided by a new method proposed, employing fully compensated prisms for electro-oculography.
