—I appreciated reading the comments of Dr Paul E. Romano et al regarding our article. Some of their thoughts were similarly raised by us during the course of our study.Monofixation occurring in one third of patients with intermittent exotropia seemed at first a surprisingly high incidence to us also. We subsequently reviewed retrospectively all patients with intermittent exotropia operated on during the three years of the study from our private practice. Those with anisometropia and amblyopia greater than one Snellen chart line were eliminated. Twenty-seven individuals were too young at the conclusion of the study to give accurate reproducible stereopsis test results and were also dropped. This left 99 patients operated on during the three years of the study with reproducible stereopsis test results obtainable at the end of the study period. These patients were not included in the published study groups since their preoperative stereopsis testing
