Abstract:
We investigated the influence of fusional divergence on the surgical results in the intermittent exotropia. Among the 56 patients with intermittent exotropia. the angle of deviation was measured during the preoperative period and the postoperative periods. The amplitude of the fusional divergence was measured with the rotary prism after the correction of the angle of deviation with the prism before the surgery. The subjects were devided into 4 groups; group one which returned to orthophoria after the overcorrection of exodeviation; group two - which did not return to orthophoria after the overcorrection of exodeviation; group three - which remained orthophoria after the correction of exodeviation; group four - which showed orthophoria initially but returned to undercorrection. There was not any significant difference between the four groups. We concluded that the influence of fusional divergence on the surgical results for intermittent exotropia was not significant enough. However, further studies should be done with more subjects for better results.
