Abstract

Objectives: 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.

Methods: 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.

Results: 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 =
