Response to: Surgical treatment of superior oblique palsy: Predictors of outcome

[...]we wrote in the material and methods section: "Our criteria for surgical treatment of intravenous (IV) nerve palsy included individualization of each case according to the cover test in the 11 positions of gaze, the position of maximum diplopia, and the results of the Lancaster test." [...]a total of 76 patients were enrolled in this study, but only data of 75 patients is given for initial inferior oblique overaction and data of 74 patients for initial superior oblique underaction, because as we stated in the end of the discussion, our study has a retrospective design, which prevented us from recording specific data such as those.
