Dynamic Fusional Vergence Eye Movements in Congenital Esotropia
PURPOSE To evaluate whether a selected group of 9 children with history of congenital esotropia is capable of producing vergence eye responses to fusional disparity stimuli. METHODS Nine children with history of congenital esotropia and 5 age-matched children with normal binocular vision were examined. Using a full-field target, vergence responses to base out 3 prism diopters placed in front ...
متن کاملVertical fusional vergence: the key to dissociated vertical deviation.
OBJECTIVES To test the previous findings of Enright that disparity-induced vertical vergence is mediated primarily by the oblique muscles, and to relate this normal eye movement pattern to the eye movement pattern seen in subjects with dissociated vertical deviation. METHODS Sixteen normal volunteers underwent 55 measurements of the cycloversion associated with prism-induced vertical vergence...
متن کاملMagnetic resonance imaging demonstrates compartmental muscle mechanisms of human vertical fusional vergence.
Vertical fusional vergence (VFV) normally compensates for slight vertical heterophorias. We employed magnetic resonance imaging to clarify extraocular muscle contributions to VFV induced by monocular two-prism diopter (1.15°) base-up prism in 14 normal adults. Fusion during prism viewing requires monocular infraduction. Scans were repeated without prism, and with prism shifted contralaterally. ...
