If the esotropic patient reports crossed diplopia, this could mean ARC (vice versa with an exotropia patient reporting uncrossed diplopia.) This is called paradoxical diplopia. Another indication of ARC is when a prism is used to neutralize the deviation, but diplopia still persists. Start studying Geometry - Trimester 2.
