The application measures horizontal strabismus in photographs with high reliability, and has a published scientific method.The average error was −0.68 Δ ± 6.1Δ, and the reliability was high (Cronbach’s α = 0.983).
The application provided measurements of the distance from the geometrical center of the cornea to the light reflex (RD) and corneal diameter (CD). The RD/CD ratio of each gaze angle was recorded. To estimate the eyes’ gaze angle, an equation to determine the best-fit line for the gaze angle data according to each RD/CD ratio was created.
