To describe the development and treatment of V-pattern and bilateral over-elevation in adduction in patients with cyclic esotropia.
Three patients with cyclic esotropia are described in retrospect. All patients underwent bilateral medial recession, while one patient additionally had a weakening procedure of both inferior oblique muscles.
All patients developed a V-pattern and bilateral over-elevation in adduction. After strabismus surgery, normal eye alignment with some signs of binocularity was reached in all three patients. Moreover, the over-elevation in adduction and V-pattern completely resolved.
V-pattern and bilateral over-elevation in adduction was seen in all patients with cyclic esotropia in the stage that fusion was disrupted. Possible explanations for the origin of these patterns are discussed. Strabismus surgery aimed to correct the horizontal esotropic angle restored fusion and eliminated the vertical incommitancies in lateral gaze, and the V-pattern.
描述周期性内斜视患者V型斜视和双侧内收时上转过度的发展及治疗情况。
回顾性描述3例周期性内斜视患者。所有患者均接受双侧内直肌后徙术,其中1例患者还同时进行了双侧下斜肌减弱术。
所有患者均出现V型斜视和双侧内收时上转过度。斜视手术后,所有3例患者均达到了正常眼位并出现了一些双眼视的迹象。此外,内收时上转过度和V型斜视完全消失。
在融合被破坏的阶段,所有周期性内斜视患者均出现V型斜视和双侧内收时上转过度。文中讨论了这些模式产生的可能原因。旨在矫正水平内斜角度的斜视手术恢复了融合,并消除了外展时的垂直非共同性斜视以及V型斜视。
