Other assessments show:
Examination of Eye Alignment/Vergence (Cover Test, CT)
NMD @Distance
NMD @Near
(normal value: orthophoria/NMD-No Movement Detected or small XP, fast recovery)
EP = Esophoria is misalignment of the eye, eye is deviated inwards
XP = Exophoria is misalignment of the eye, eye is deviated outwards
Examination of Eye Alignment/Posture (Howell Card) by 6^ Base Down on Right eye
Distance: 1 EP (yellow part)
Near: 2 XP (blue part)
(normal value: 0-1 EP (yellow part) or 0-3 XP (blue part) @Distance; and 0-6 XP (blue part) @Near)
EP = Esophoria is misalignment of the eye, eye is deviated inwards
XP = Exophoria is misalignment of the eye, eye is deviated outwards
NRA (Accommodation analysis – ability to relax accommodation) by plus lens

18/26cm, 18/26cm, 18/26cm, 18/28cm, 18/28cm, 18/28cm
(normal value: Break/Recovery in less than 10cm or to the nose, TTN)
