Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Develop and evaluate a new smartphone based app to screen for and measure eye misalignment (strabismus). The investigators will validate the app against simulated strabismus of known magnitude and common clinical tests. They will evaluate the app as a screening tool in high risk populations, to determine the sensitivity and specificity. They hypothesize that the app can measure to within 2 units (prism diopters) of the ground truth, and that it will be correlated with gold standard tests.
