Ten years follow-up of surgery for intermittent exotropia.

Ten years post-operative follow-up of 25 consecutive patients with intermittent exotropia have been performed. 13/25 patients are at follow-up fine, that is small and symptom-free exoforia, good sensorial binocular functions of normal type, sufficient although subnormal fusional amplitude and never exotropia. 8/25 patients are fair, that is only occasionally momentary occurrence of exotropia and binocular complaints. 4/25 patients are orthoptically poor (suppression on all tests), but without complaints. Eye position is on a whole unchanged for distance, whereas exodeviation has increased about 10 PD for near during the 10 years post-operative observation time (no orthoptic treatment in this period). 22/25 patients indicated spontaneously at the follow-up examination that they considered their squint cured. None of the patients had cosmetic or functional restrictions in jobs or studies.
