The angle of deviation of the fovea-disc axis from the horizontal axis (FoDi angle) ranged from-24.40[degrees] to +11.60[degrees], with an average of -6.43[+ or -]4.9[degrees].
To investigate the relationships between angle of deviation, fusional convergence and divergence amplitudes, AC/A ratio, NPC, and myopia-phoria in IXT, we studied a series of patients referred to our department in the last five years.
Also angle of deviation at near and duration of deviation can be a useful predictor for poor stereoacuity levels.
Angle of deviation was measured both for >6m and for near and in case of spectacles both with and without them by Hirschberg test and prism bar cover test.
The prism and alternate cover test was used to measure the angle of deviation from far (6 m) and near (33 cm) distance.
[2] Why would changing from spectacles to contact lenses possibly cause a change in the angle of deviation for near vision for a patient with the clinical data shown in Image A?
On the other hand, the obtained new transition curves are compared with the most used transition curves (clothoid, sinusoidal and bloss) in highways with regard to curvature change, angle of deviation, superelevation, lateral acceleration and total curve length.
If the angle of deviation (or incidence angle) is large, flow separation occurs.
Pre-determined formulae determined from empirical data are used to determine the amount of 'strengthening' or 'weakening' that should be performed for a particular squint and given angle of deviation. Different procedures can be performed for the same operation and the importance is the angle between the eyes, not which eye is operated.
