Purpose: The dissociated strabismus in which an abductor component is prominent is known as dissociated horizontal deviation (DHD). Asymmetric horizontal deviation and variable angle deviation are the two characteristic elements of DHD. We studied the clinical features and postoperative results of DHD cases. Material and Methods: Thirteen patients, 4 males and 9 females were included in this study. The mean age was 9.6±5.6 (range 4 to 21) years old. The patients were diagnosed as DHD by alternating cover-uncover and prism cover tests. All patients underwent surgery. DHD cases manifesting with exodeviation underwent 8 mm lateral rectus recession. DHD cases manifested with esodeviation underwent 6 mm lateral rectus recession. If dissociated vertical deviation (DVD) or inferior oblique muscle overaction were present they were treated at the same operation. Results: DHD was present as exodeviation in 10 cases (77%) and as esodeviation in 3 cases (23%). It was unilateral in 7 cases (54%) and bilateral in 6 cases (46%). The mean value of maximal deviations measured in prominent DHD eyes was 36.5±2.4 (range 25 to 55) prism diopters. The mean horizontal deviation difference between the two eyes was 30.0±10.2 (range 15 to 55) prism diopters preoperatively. All .of our cases were completely within the limits of 10 prism diopters after surgical treatment.Conclusion: Clinical picture of DHD is very confusing. The deviation between eyes is not constant and at different times different deviations can be observed in both eyes. Eight mm ipsilateral lateral rectus recession may be the choice of treatment when DHD is associasted with exodeviation and 6 mm ipsilateral lateral rectus recession when associasted with esodeviation.
