斜视治疗应重视双眼视觉功能的恢复

Pay attention to recovery of the binocular vision following strabismus surgery

斜视治疗的主要目的应是改变或恢复眼球运动和知觉方面的病理状态,手术的目标应该包括消除复视和混淆视,这样不仅患者外观和心理状态可得到改善,而且相当多的患者可恢复双眼视觉功能,部分患者可扩大周边双眼视野。我们应该深入研究和了解患者手术前、后的双眼视觉,并将立体视觉和双眼融合功能检查作为常规项目,推广使用三棱镜遮盖法;临床检查工作应深入细致。只有视轴偏斜得到矫正,患者获得双眼视觉,斜视治疗的效果才能得到巩固。

The primary goal of strabismus treatment is to correct and reverse a pathologic condition. Successful treatment is associated with relief from visual confusion or diplopia, a very high incidence of sensory binocular vision, an expanded peripheral visual field, and improved psychosocial function. Binocularity before and after strabismus surgery should be well understood. The stereopsis or sensory fusion should be examined routinely. The measurements should be repeated with the angle of strabismus neutralized with loose prisms. Eye misalignment is measured using the alternate prism and cover test, Eye alignment is measured using the simultaneous prism and cover test. The recent find is that the maximum horizontal deviation that will support true stereopsis is 4△. The functional benefit can usually be obtained in the form of improved binocularity and, consequently, better stability of ocular alignment.
