This study aims to evaluate the effects of acquired esotropia on vestibulo-ocular reflex (VOR) gain in children using video (vHIT) and functional head impulse (fHIT) tests.
A total of 62 children aged 6-18 years, with acquired esotropia and normal vision, were evaluated in the study. The patients were divided into two sub-groups: accommodative and non-accommodative. VOR gains were analyzed by performing lateral canal vHIT and fHIT with monocular and binocular recordings by a single examiner.
Seventeen (10 male, 7 female) children with accommodative esotropia, 24 (14 male, 10 female) children with non-accommodative esotropia, and 21 (8 male and 12 female) healthy controls were included in this study. The vHIT findings did not differ between the groups (p˃.05). In the non-accommodative esotropia group, the location of the camera in both binocular and monocular vHIT recordings made a significant difference in the left VOR gain (p = .025, z = -2.243, p = .032, and z = -2.143, respectively), but no difference was observed in the right VOR gain. In the accommodative esotropia group, while the camera was on the left there was a significant difference in the right VOR gain between binocular and monocular recordings (p = .016, z = -2.413) but no difference was observed in the left VOR gain. No overt or covert saccade was detected in any group.
The statistical differences found in vHIT and fHIT in acquired esotropia patients are thought to be sporadic and based on the results of this study no correction or change in recording technique is required for vHIT or fHIT in children with acquired esotropia.
本研究旨在使用视频（vHIT）和功能性头部脉冲（fHIT）测试评估获得性内斜视对儿童前庭眼反射（VOR）增益的影响。
本研究共纳入 62 名年龄在 6-18 岁之间、患有获得性内斜视且视力正常的儿童。将患者分为调节性和非调节性两组。通过由一名检查者进行单侧和双侧记录， lateral 管 vHIT 和 fHIT 分析 VOR 增益。
本研究纳入 17 名（10 名男性，7 名女性）调节性内斜视儿童、24 名（14 名男性，10 名女性）非调节性内斜视儿童和 21 名（8 名男性和 12 名女性）健康对照者。各组间 vHIT 结果无差异（p˃.05）。在非调节性内斜视组中，双侧和单侧 vHIT 记录中相机的位置在左侧 VOR 增益方面有显著差异（p =.025，z = -2.243，p =.032，z = -2.143），但右侧 VOR 增益无差异。在调节性内斜视组中，当相机在左侧时，双侧和单侧记录之间的右侧 VOR 增益有显著差异（p =.016，z = -2.413），但左侧 VOR 增益无差异。在任何一组中均未检测到显性或隐性扫视。
在获得性内斜视患者中，vHIT 和 fHIT 中发现的统计学差异被认为是偶然的，并且根据本研究的结果，对于患有获得性内斜视的儿童，无需对 vHIT 或 fHIT 进行校正或改变记录技术。
