From: The role of diagnostic monocular occlusion test in basic type intermittent exotropia

Response to diagnostic monocular occlusion. The distance deviation angle significantly (5 PD or more) increased in 25 patients (18.4%) and significantly decreased in 23 patients (16.9%). The near deviation angle significantly increased in 79 patients (58.1%) and significantly decreased in 11 patients (8.1%).
