Abstract
We compared preoperative binocularity and binocular visual field with postoperative ones in heterotropic patients without any treatment during the critical period for the development of binocular visual function. Nineteen patients were enrolled: seven of them had esotropia and twelve patients had exotropia. All of them showed suppression of deviating eye. The mean preoperative extent of binocular visual field measured by Goldmann perimeter was 112.1 degrees(+/-20.3) in esotropia, 114.4 degrees(+/-9.5) in exotropia. In postoperative Bagolini test, six of esotropic patients (85.7%) and twelve exotropic patients (100%) showed fusion. In Titmus test, one case of esotropic patient (14.3%) showed stereopsis of 100 arc of second while seven cases of exotropic patients(58.3%) showed stereopsis of 100 arc of second or more. Mean postoperative extent of binocular visual field was 113degree(+/-13.5) in esotropia and 112.9degree(+/-7.4) in exotropia. There was no significant difference between pre- and post operative extent of binocular visual field. Conclusively, we suggest the binocularity could be improved by the surgical alignment in adults with long-standing strabismus. We could not observe, however, any significant difference between pre- and postoperative extent of binocular visual field.
