ABSTRACT Purpose: To evaluate the clinical and surgical impacts of phenomena that could occur in intermittent exotropia. Methods: The medical records of intermittent exotropia cases from 1991 to 2014 were retrospectively reviewed. All patients underwent a series of measures, including a protocol to assess monocular occlusion based on the propedeutics proposed by Kushner. Results: Outdoor sensitivity was observed in 31% of patients with an undercorrection rate of 44% vs. 18% of cases with no outdoor sensitivity. After 1 h of monocular occlusion, 41% of all patients achieved an increase in deviation with an undercorrection rate of 40%, whereas 25% did not. Conclusion: The results show the importance of complete propedeutics, since there is a higher rate of late undercorrection in cases with outdoor sensitivity and increased deviation after occlusion.
