ABSTRACT
In order to evaluate the incidence of lateral incomitance after monocular recession and resection and compare the amount of correction achieved by monocular recession and resection according to the gaze direction and distance in exodeviations, we measured the angle of deviation in primary, right, left, up, down and near gaze before and after monocular recession and resection. Lateral incomitance was developed in11.4%(9/79) after monocular recession and resection. The amount of correction of the deviation toward the side of operated eye was larger than that of the deviation in primary position(p=0.002), but the amount of correction of the deviation toward the side of non-operated eye, up, down and near gaze was all smaller than that of the deviation in primary position(all, p<0.01).
