Torsional 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 کاملRepeatability and agreement in the measurement of horizontal fusional vergences.
PURPOSE This study was designed to determine the repeatability of fusional vergence ranges measured using the rotary prisms in the phoropter and in free space using the prism bar. The level of agreement between the two methods was also investigated. METHODS In two separate sessions, negative and positive fusional vergence ranges (NFV and PFV, respectively) were measured at distance and near i...
متن کاملFusional 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 کاملMeasurement and diagnosis of cyclodeviation by the after-image method.
Lesions involving the vertical muscles or their nerve supply usually result in some degree of torsional deviation of the eye which may produce intractable and distressing asthenopia. Although cyclophoria has long been recognized and has been demonstrated with such apparatus as the Maddox rod, Maddox wing, Maddox double prism, and synoptophore, it is nevertheless frequently overlooked. Moreover ...
