An interventional study of Cartoon video fixation target and cartoon character voice audio instructions during Humphrey perimetry and Usual Care procedures during Humphrey perimetry for children in Glaucoma, Suspect, Optic Nerve Hypoplasia and Abnormalities of the Central Nervous System and Congenital Coloboma of the Optic Nerve, sponsored by Nova Southeastern University. Completed at 1 site in United States. Open to participants aged 5 Years to 8 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-30.

The majority of young children do not think that visual field (VF) testing of peripheral vision is similar to a game; therefore, it is not surprising that they have difficulty maintaining attention during VF testing and thus the test reliability suffers as a consequence. Poor VF reliability has been a longstanding, major issue since it leads to an increased number of tests and/or longer duration of time needed to determine when there are true vision losses. Providers are less likely to obtain VF tests in children since the results are of doubtful value and challenging to interpret when they are inconsistent. Effectively this means that children with untreated, slowly progressive eye diseases may go undiagnosed and incur greater visual losses. The investigators aim to create a prototype device that the investigators hypothesize will make VF testing more engaging for young children, thus increasing their attention and consistency of their responses to the test stimuli, which in turn should improve VF reliability. The components include a microdisplay video screen (1.5" diameter) as the fixation target (instead of the standard LED light) displaying video clips of popular cartoon characters, and audio clips of impersonated cartoon character voices presented by the test operator to provide instructional feedback based on the child's performance during testing. Improved VF reliability from the investigators intervention would translate to improved diagnosis and care for young childrens' peripheral vision loss through widespread implementation of the investigators innovative, affordable and readily adoptable system at eye care providers' offices.

Humphrey Visual Field Test-Retest Variability of Mean Deviation scores (dB)
Within subject, the investigators will determine the coefficient of variation in the mean deviation scores obtained at the two sessions a week apart (dB). The investigators will test for significant differences between subjects who receive the intervention versus the usual care control group for the test-retest variability.
Time frame: 1 week
Humphrey Visual Field Reliability Indices and Ratings
The investigators will test for significant differences between subjects who receive the intervention versus the usual care control group for the visual field reliability criteria (false negatives, false positives and fixation losses; expressed as %), and operator ratings (subjects' fixation, cooperation and fatigue; scale 1 to 5).
Time frame: 1 week
