Is 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...

determinant of the hankel matrix with binomial entries
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
15 صفحه اولFusional 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 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...
