—In response to Dr Giangiacomo's question, all PA study patients¹ had their ocular deviations measured at least twice on separate occasions before the first randomization, with agreement on both simultaneous and alternate prism and cover tests to within 5 prism diopters to demonstrate stability of their deviation. Certainly, those in the PA groups (PAR/PS, PAR/ES, and PANR/ES [PA nonresponders who underwent surgery for their deviation at entry into the study]) had more measurements in the course of prism adjustment than patients in the control group (non-PA/ES). There was no difference in the number of measurements between the PAR/PS and PAR/ES groups. It is theoretically possible that the superior results in the PAR/PS group were due only to additional measurement, although this seems unlikely. In the PAR/PS group, the target angle for surgery was always greater than or equal to the entry angle of deviation, with the increase . . . [Full Text PDF of this Article]
