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.
异侧偏盲性缺损可能导致半视野滑动现象。我们报告1例双眼鼻侧视野缺损和2例双眼颞侧视野缺损导致半视野滑动的病例。2例双眼颞侧视野缺损患者均接受了斜视手术。1例采用可调节缝线的患者报告在调整过程中，视轴对准时中央视野条带出现遗漏或重复，但2例患者的半视野滑动均未得到长期改善。2例患者视野改善后半视野滑动消失，其中1例接受了斜视手术。对于半视野滑动患者可进行斜视手术以恢复双眼视觉功能。视野改善的患者可能有更好的感觉预后。
