Fusional Vergence Detected by Prism Bar and Synoptophore in Chinese Childhood Intermittent Exotropia
Purpose. To measure the changes in fusional vergence in Chinese children with intermittent exotropia (IXT) and the association with the control of IXT. Methods. Ninety-two patients with IXT (8-15 years old) were compared with 86 controls. Exodeviation control was evaluated using the Revised Newcastle Control Score. Angle of deviation was measured using prism and alternate cover testing at dista...
متن کاملTorsional fusional vergences and assessment of cyclodeviation by synoptophore method.
Two special slides, one in front of one eye and one in front of the other eye, were placed in the housings of a synoptophore. The slides were originally designed for the diagnosis and measurement of cyclodeviation, but they were utilised in this study for the measurement of torsional fusional vergence. This was measured by rotating one of the housings of the synoptophore and noting the point of...
متن کاملCorrelation between Worth Four Dot Test Results and Fusional Control in Intermittent Exotropia
PURPOSE To compare the results of Worth 4-dot test (WFDT) performed in dark and light, and at different distances, with fusional control in patients with intermittent exotropia (IXT). METHODS Dark and light WFDT was performed for new IXT subjects at different distances and the results were compared with level of office-based fusional control. RESULTS Fifty IXT patients including 17 male and...
متن کاملIs the Aligning Prism Measured with the Mallett Unit Correlated with Fusional Vergence Reserves?
BACKGROUND The Mallett Unit is a clinical test designed to detect the fixation disparity that is most likely to occur in the presence of a decompensated heterophoria. It measures the associated phoria, which is the "aligning prism" needed to nullify the subjective disparity. The technique has gained widespread acceptance within professions such as optometry, for investigating suspected cases of...
متن کاملFusional Vergence Dysfunction a Case Report
Fusional vergence dysfunction is a binocular condition that is relatively easy to diagnose and treat but is often overlooked. FVD can negatively impact an individual’s ability to function, particularly when performing near work. A 17-year-old white female presented to our clinic with visual symptoms associated with sustained near work. The findings were characterized by normal phorias, poor but...
