Selective surgery for intermittent exotropia based on distance/near differences.
BACKGROUND Classic teaching suggests that surgery for intermittent exotropia should be based on distance/near differences. Divergence excess, according to tradition, should be treated with symmetric lateral rectus recessions; simulated divergence excess and basic deviations should be treated with a recess/resect procedure. This teaching, to our knowledge, has not been systematically tested. O...
متن کاملIncomitance and Eye Dominance in Intermittent Exotropia
Purpose To determine if the deviation angle changes in subjects with intermittent exotropia as they alternate fixation between the right and left eye in primary gaze. Methods In this prospective observational cohort study, 37 subjects with intermittent exotropia were tested for evidence of incomitance. The position of each eye was recorded with a video tracker during fixation on a small centr...
متن کاملVariability of stereoacuity in intermittent exotropia.
PURPOSE Distance stereoacuity is used to monitor deterioration of intermittent exotropia (IXT), but variability of stereoacuity has not been studied rigorously. The purpose of this study was to assess the variability of stereoacuity over one day in children with IXT. DESIGN Prospective cohort study. METHODS Twelve children with IXT were recruited. Stereoacuity was assessed using the Frisby ...
متن کاملSuppression and retinal correspondence in intermittent exotropia.
Suppression scotomas and retinal projection (retinal correspondence) were measured in six intermittent exotropes during deviation. Measurements used red-green anaglyph stimuli presented on a black background which could be varied from 3.4 minutes of arc to 3 degrees 24'. Results showed non-suppression of all points between the fovea and the diplopia point. Harmonious anomalous retinal correspon...
متن کاملExcess cyclovergence in patients with intermittent exotropia
Recently, we developed a model of binocular fixation. This model predicts the amount of cyclovergence as a function of target elevation and horizontal target vergence. The prediction derives from the assumption that version and vergence add linearly and that the eye positions are constrained in three respects: (1) the foveae of the two eyes are directed towards the target, (2) the version compo...
