Clinical and computer-assisted analyses of preoperative and postoperative accommodative convergence and accommodation...

A group of 329 patients who underwent bilateral medial rectus muscle recession for esodeviation were analyzed for factors most closely correlated with the outcome. The data evaluated included age of onset of strabismus, refractive error, year of surgery, age of surgery, sex, preoperative esodeviation, and clinical assessment of preoperative and postoperative heterophoria. Linear regression analysis was used to evaluate the relationships of these parameters. Computer-assisted logistic regression analyses and discriminant analyses were used to assess predictive variables for a postoperative increase or decrease in the accommodative convergence and accommodation (AC/A) relationship represented by the clinical assessment method.
