Trial Summary
What is the purpose of this trial?This trial aims to improve vision tests for young children by using a small screen with cartoon videos and voices. This approach helps keep children engaged, making the test results more reliable and aiding in better diagnosis and care for vision problems.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications.
What data supports the effectiveness of the treatment involving cartoon video fixation target and cartoon character voice audio instructions during Humphrey perimetry for pediatric eye examinations?
Research shows that using engaging visual tasks, like animated characters, can help children maintain focus and improve the quality of eye measurements. Children enjoyed these tasks, which led to better pupil responses, suggesting that similar engaging methods could be effective during Humphrey perimetry.
12345How is the treatment using cartoon video and audio instructions during Humphrey perimetry different from other treatments for pediatric eye examinations?
This treatment is unique because it uses engaging cartoon videos and character voices to hold children's attention during eye tests, making the experience more enjoyable and potentially improving test accuracy compared to traditional methods that may not capture children's interest as effectively.

Maintaining fixation by children in a virtual reality version of pupil perimetry. [2023]The assessment of the visual field in young children continues to be a challenge. Children often do not sit still, fail to fixate stimuli for longer durations, and have limited verbal capacity to report visibility. Therefore, we introduced a head-mounted VR display with gazecontingent flicker pupil perimetry (VRgcFPP). We presented large flickering patches at different eccentricities and angles in the periphery to evoke pupillary oscillations, and three fixation stimulus conditions to determine best practices for optimal fixation and pupil response quality. A total of twenty children (3-11y) passively fixated a dot, counted the repeated appearance of an animated character (counting task), and watched an animated movie in separate trials of 80s each (20 patch locations, 4s per location). The results showed that gaze precision and accuracy did not differ significantly across the fixation conditions but pupil amplitudes were strongest for the dot and count task. The VR set-up appears to be an ideal apparatus for children to allow free range of movement, an engaging visual task, and reliable eye measurements. We recommend the use of the fixation counting task for pupil perimetry because children enjoyed it the most and it achieved strongest pupil responses.

Patient satisfaction for the two instruments was compared.

Can Psychophysics Be Fun? Exploring the Feasibility of a Gamified Contrast Sensitivity Function Measure in Amblyopic Children Aged 4-9 Years. [2020]Routine assessments of the Contrast Sensitivity Function [CSF] could be useful for the diagnosis and monitoring of amblyopia. However, current CSF measures are not clinically practical, as they are too slow, too boring, and too uncomfortable to sustain a young child's interest. Here we assess the feasibility of a more gamified approach to CSF testing, in which a maximum likelihood psychophysical algorithm (QUEST+) is combined with a largely unconstrained user interface (no fixation target, head restraints, or discrete trials). Twenty-five amblyopes (strabismic, anisometropic, or mixed) aged 4.0-9.2 years performed the gamified CSF assessment monocularly (once per eye). The test required the child to "pop" (press) grating stimuli as they "bounced" around a tablet screen. Head tracking via the tablet's front-facing camera was used to adjust for variations in viewing distance post hoc. CSFs were fitted for each eye, and Area Under the CSF (AUCSF) computed as a summary measure of sensitivity. The results showed that AUCSF measurements were able to separate moderately and severely amblyopic eyes from fellow eyes (case-control effect), and to distinguish individuals with varying degrees of vision loss (dose effect). Even the youngest children exhibited no difficulties completing the test or comprehending what to do, and most children appeared to find the test genuinely enjoyable. Informal feedback from a focus group of older children was also positive, although potential shortcomings with the present design were identified. This feasibility study indicates that gamified, child-friendly vision assessments have promise as a future means of pediatric clinical assessment. Such measures could be particularly valuable for assessing children outside of conventional eye-care facilities (e.g., home-monitoring, school screening).
Feasibility and outcome of automated static perimetry in children using continuous light increment perimetry (CLIP) and fast threshold strategy. [2022]Visual field testing in children is always a challenge as testing is hampered by fatigue effects, easy distraction and lack of comprehension. For that reason new testing strategies for automated perimetry have mainly been evaluated on adults. We tested the feasibility and outcome of automated static perimetry in children in a standard clinical setting.
