(38) In these cases, the alternating cover test typically reveals a vertical deviation
that will increase in contralateral gaze, reduce in ipsilateral gaze, increase on ipsilateral head tilt and decrease on contralateral head tilt.
It differs from the current $6180 Evolution 1000 Pilot model mainly because it has a VDI (vertical deviation
indicator) and LDI (lateral deviation indicator) navigation display for flying approaches.

[DELTA]z and (b) influence of vertical deviation
on the illumination uniformity and the light utilization efficiency.
In SO palsy, a vertical deviation
usually coexists which may be compensated with an anomalous head posture.
When a vertical deviation
is greatest in adduction (overelevation in adduction), the primary oblique muscle overaction could be the commonest cause .
Boasting a 3.5-inch sunlight readable liquid crystal display (LCD) with built-in GPS, G5 displays attitude, ground track, altitude, airspeed, groundspeed, vertical speed, slip/skid, course (lateral) deviation, vertical deviation
and incorporates a dedicated HSI page.
Most HSIs have vertical deviation
indicator pointers (VDIs) on one or both edges of the display that drop into view when a valid glideslope signal is received.
The Cadre group showed slightly higher vertical deviation
at near than the Control group as time progressed.
Indications for surgery are vertical deviation
in primary gaze, deviation-induced amblyopia, diplopia in primary gaze, and restricted binocular fields.
Krimsky and PBCT was done with base up prisms which confirmed vertical deviation
of 10 pd.
