“…ET and VOG are currently used in various areas associated with visual functioning, including nystagmus, 6–8 oculomotricity, 9–14 contrast sensitivity, 15 visual acuity, 15 pupillography, 16 cyclotorsion, 17,18 and primarily for detecting and/or quantifying ocular misalignment, whether it be heterophoria 19–24 or heterotropia 25–52 …”

“…ET and VOG are currently used in various areas associated with visual functioning, including nystagmus, [6][7][8] oculomotricity, [9][10][11][12][13][14] contrast sensitivity, 15 visual acuity, 15 pupillography, 16 cyclotorsion, 17,18 and primarily for detecting and/or quantifying ocular misalignment, whether it be heterophoria [19][20][21][22][23][24] or heterotropia. In recent years, various investigations have compared the measurement of strabismus using APCT and VOG, showing that both measurements are interchangeable due to the high precision of the technology.…”

Purpose: The aim of the study was to compare distance vision measurements obtained with video oculography (VOG) and an alternate prism cover test (APCT). Design: Single-center, retrospective, and cross-sectional. Methods: Eighty-seven subjects with strabismus were included. All patients underwent an optometric examination. The measurement of strabismus in distance vision was performed with the best optical correction using the APCT and the VOG GazeLab. Subjects were divided according to the type of strabismus; 41 were esotropic and 46 were exotropic. Results: The general comparison of APCT and VOG showed a mean difference of 0.60±2.74 prism diopters (Δ), not observing statistical differences between both methods (P=0.059) and presenting a correlation of 0.976 (P<0.001). Using APCT, the mean amount of esotropia for the group was 18.31±11.64 Δ and that of exotropia was 19.62±8.80 Δ. Compared with the VOG, the mean value of esotropia for the group was 18.65±11.65 Δ and that of exotropia was 19.48±8.62 Δ. The means are statistically different for the esotropia group (P=0.005) but not for the exotropia group (P=0.318). There was a high direct correlation between the methods of measurement for both the esotropic (R=0.980; P<0.001) and exotropic patients (R=0.975; P<0.001). Bland-Altman analysis shows a mean difference of 1.37±2.76 Δ for the esotropia patients and 0.31±2.66 Δ for the exotropic patients, respectively. Conclusions: This study demonstrated comparable results in measuring strabismus between VOG and APTC for esotropia and exotropia, with an excellent correlation between both methods and good agreement, especially in subjects with exotropia.

“…Saccadic eye movements are important for rapid gaze shifting to visual targets. Saccade analysis has not yet become widespread in the general ophthalmology practice but is recently being performed extensively for eye disorders such as strabismus 11,12 . Therefore, it is hoped that the performance of saccades in strabismus and ocular motility disorders will be explored in future studies.…”

Saccade occurs when looking at an object, and it is known that the saccade velocity can be quickened according to the wide angle of saccade amplitude.…”

Purpose: This study aimed to analyze saccades in patients with orbital-wall fractures with little or no ocular motor impairment. Methods: We included 7 eyes of 7 patients with unoperated orbital-wall fractures (3 cases of orbital-floor fractures and 4 cases of medial orbital-wall fractures) with mild or no diplopia who presented to our hospital between August 2019 and March 2021. Eye movements were assessed at the first visit and after 1 month using the Hess area ratio according to the Hess screen test, binocular single vision (BSV) scores (total 59 points) obtained using Goldman perimetry, and maximum velocity and amplitude of saccades within 15 degrees obtained using an eye tracker system. Results Hess area ratio and BSV scores at the first visit and after 1 month were 88.6±8.2% and 97.4±3.6% and 49.6±8.5 points and 53.5±6.6 points, respectively, with no significant change (Hess area ratio, P=0.06; BSV, P=0.44). Next, the authors compared the velocity and amplitude of the saccades between the first visit and 1 month later and found no significant changes in any of the 4 directions (adduction, abduction, upgaze, and downgaze). Similarly, no significant differences were observed between the velocity and amplitude of the saccades between the injured and noninjured eyes, both at the first visit and after 1 month. Conclusions: In patients with orbital-wall fractures with little or no eye movement impairment, eye tracker-based saccade analysis showed that the saccade velocity and amplitude did not change during the natural course of healing of the fracture.
