Fig. 2 — Correlation between the corneal reflection test and the alternate prism cover test (APCT) at distance for the strabismic angle in exotropia. (A) The correlation between the conventional Krimsky test and the APCT was close to Y = 0.738X (X, prism diopter measured with the conventional Krimsky test; Y, prism diopter measured with the APCT). (B) The correlation of the distance Krimsky test and the APCT was found to be Y = 0.981X (X, prism diopter measured with the distance Krimsky test; Y, prism diopter measured with the APCT). The extent of the concordance between the distance Krimsky test and the APCT was higher than that of the conventional Krimsky test and the APCT in exotropia.
