The editors of the Archives and Kushner et al1 are to be congratulated on their courage in publishing an article that presents new data and data analysis refuting a previous conclusion published by these authors in the Archives.2 The publication of this article is also unusual because it includes so much in the way of negative results from reasonable attempts to find additional useful parameters to improve the design and success rates of horizontal strabismus surgery.
My purpose in writing is to offer verification of these negative results. In 1986 in the Archives,3 I published an exponential dose-response curve based on the surgical results of bilateral medial rectus recessions performed on a group of 68 children with acquired esotropia. Like Kushner et al, I found that the prediction of response to strabismus surgery was not improved significantly with the inclusion of age and/or preoperative refractive error beyond
