(a) Right eye fixing to a central target, and left eye occluded, A is the distance from the CLR to nasal corneal limbus. (b) Left eye fixing to a central target, and right eye occluded, B is the distance from the CLR to nasal corneal limbus. (c) Both eyes open, and right eye fixating on a central target, C is the distance from the right CLR to nasal corneal limbus. The distance from the left CLR to nasal corneal limbus is D. (d) Both eyes open, and left eye fixating on a central target. (The above illustrations are the original works of the authors).

The relationship between angle of deviation from the Photo-Hirschberg test with APCT at N.
The solid line is the line of equality and the zone between dotted lines represents range ±10 PD of the APCT values. The acceptable area were b and c. The unacceptable area were a and d. (ET = esotropia;XT = exotropia).
Fig 4.
The relationship between angle of deviation from the Krimsky test with APCT at N.
The solid line is the line of equality and the zone between dotted lines represents range ±10 PD of the APCT values. The acceptable area were b and c. The unacceptable area were a and d. (ET = esotropia; XT = exotropia).

The relationship between angle of deviation from the Photo-Hirschberg test with APCT at D.
The solid line is the line of equality and the zone between dotted lines represents range ±10 PD of the APCT values. The acceptable area were b and c. The unacceptable area were a and d. (ET = esotropia; XT = exotropia).
