Abstract
Heteronymous hemianopic defects may lead to the hemifield slide phenomenon. We report one case of binasal and two of bitemporal visual field defects causing hemifield slide. Both patients with bitemporal visual field defects underwent strabismus surgery. One with adjustable sutures reported omission or duplication of a central strip of vision dependent on alignment during adjustment, but did not have long-term improvement of hemifield slide in two patients. Visual field improvement resolved hemifield in two patients, one of whom had strabismus surgery. Strabismus surgery to restore binocular visual function can be performed in hemifield slide patients. Patients with improving visual fields may have a better sensory prognosis.
