Pattern strabismus is defined as a difference in the magnitude of a horizontal deviation between up and downgaze. It is also known by its alternative term “alphabet patterns”. [1] V pattern. Example: V pattern exotropia has a greater magnitude of deviation in up gaze than down gaze. (Figure 1) Figure 1: V-pattern exotropia. [2]

2020年12月28日 · V-pattern: When the eye converges as the eye moves from up to downgaze, a V-pattern is present. In V-pattern esotropia, the deviation is more in downgaze than in upgaze, and in V-pattern exotropia the deviation is more in upgaze than in downgaze ( Figure 3 ).

2021年12月9日 · A V-pattern results in greater exotropia (or less esotropia) in upgaze and greater esotropia (or less exotropia) in downgaze. Not all V-pattern strabismus is associated with oblique muscle...

2016年6月4日 · The terms “A” and “V” pattern describe horizontal strabismus that is vertically incomitant. It is characterized by a substantial difference in the horizontal deviation between the midline upgaze and downgaze positions.

Surgical treatment of Exotropia with V-pattern strabismus without oblique muscle overaction. Exotropia with V-pattern - Bilateral lateral rectus muscle recessions with up shift Or. Exotropia with V-pattern - lateral rectus muscle recessions with up …

“A” and “V” patterns describe horizontal strabismus that is vertically incomitant and is characterized by a substantial change in the horizontal deviation from the midline position in upgaze as compared to downgaze. Approximately 12–50% of strabismus patients have “A” or “V” patterns [1 – 4].

V-pattern exotropia is a unique form of strabismus characterized by an outward deviation of the eyes, with the angle of misalignment increasing in downward gaze. It is important to …

2021年9月20日 · Now, when we talk about A and V pattern strabismus and how we’re going to treat that, so A and V pattern — we have deviations which are greater in one direction, upgaze or downgaze, than they are in the primary position.

2020年7月22日 · The V pattern was the most common alphabetical pattern noted in a series of 101 patients with DRS (75% in the study of Isenberg and Urist). In this study, A pattern and no pattern were noted equally. 38 Some patients can also present with X pattern.

V pattern strabismus in craniosynostosis may be related to anatomical malposition of the rectus muscles. This may be documented by orbital imaging, which could also aid in planning the surgical approach.
