Oculomotor Assessments: Mean Scores and Number of Patients who Failed Assessment (based on the criteria listed in Table 1)

Oculomotor Assessments	Mean ± 1 SD [Median, Range]	Number of Patients Who Failed Criteria (n =140)

DEM – Horizontal scanning time (standard score)	90.85 ± 30.9 [97, −100 to 133]	42 (30.0%)
DEM – Ratio score (Horizontal/Vertical; standard score)	88.19 ± 26.8 [92, −20 to 151]	54 (38.6%)

Measures of vergence and accommodation (mean ± one standard deviation (SD), median, and range) and the number of patients who failed the test based on the criteria listed for the respective tests in Table 1. Monocular measures were recorded from the right eye of the patient. DEM = developmental eye movement test. Δ = prism diopter; cpm = cycles per minute; D = diopters
