[Pay attention to recovery of the binocular vision following strabismus surgery].
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(Delta). The functional benefit can usually be obtained in the form of improved binocularity and, consequently, better stability of ocular alignment.
