Study summary

The purpose of this protocol is to determine if the Welch-Allyn Spot Vision Screener (SPOT) is effective at detecting various risk factors for poor vision in developmentally delayed children. These children have a higher percentage of vision disorders than the average population. The SPOT screen itself takes about six seconds to complete. It produces a photograph of the eye and a print out with amount of hyperopia, myopia, astigmatism and pupil size. The subject will have three SPOT screens around the time of their standard of care eye exam. The data obtained from the three SPOT screens will be compared among themselves for accuracy and to the findings of the clinical eye exam.

What researchers measure

Primary outcomes

  1. the SPOT will be effective in screening for amblyogenic risk factors

    the Spot has a sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) necessary to appropriately perform visual triage in developmentally delayed children

    Time frame: 12 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2017 (actual). Primary completion is estimated for May 2019, 24 months after the start.

Of 51 non-industry observational studies under Vision Disorders, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 42. This study's planned 24 months is close to that.

Counting every sponsor, half of 58 studies reached it within 23 months; a quarter within 12 and three quarters within 52.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 23, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
