Area of Science:

Ophthalmology
Pediatric Vision Science

Background:

Establishing normal visual field thresholds in children is crucial for early detection of visual impairments.
Traditional perimetry methods can be challenging for pediatric populations.

Purpose of the Study:

To demonstrate and explore the efficacy of a novel game-based perimetry approach for determining normal visual field thresholds in children.
To establish normative data for a game-based visual field test in a pediatric cohort.

Main Methods:

One hundred eighteen children (mean age 8.0 ± 2.8 years) underwent testing with the 'Caspar's Castle' game-based visual field test.
Thresholds were measured at four retinal locations using staircase algorithms.
Relationships between visual field thresholds, age, and variability were analyzed.

Main Results:

The game-based visual field test successfully established threshold estimates across all tested children.
A significant inverse relationship was observed between threshold size and increasing age.
Intra- and intersubject variability decreased with increasing age.

Conclusions:

Normal visual field thresholds were successfully established for specific retinal locations in children using a novel game-based perimetry test.
The findings support the development of this game-based approach as a screening tool for pediatric visual field assessment.
