Three patients with temporal displacement of the macular secondary to retrolental fibroplasia had true strabismus in associations with amblyopia and pseudostrabismus related to a large, positive angle kappa. In one case, a headturn associated with the neutral point of nystagmus was also a presenting problem. Ocular deviation was measured by the light reflex test and the prism cover test, with particular attention paid to adequate cosmetic alignment. Large amounts of prism placed before the fixating eye resulted in loss of visual acuity, while eyes placed in a parallel position by surgical means may not appear to be straight. Thus, surgery can result in parallel ocular alignment while prismatic therapy may be required to center the pupillary light reflex and to provide satisfactory cosmetic appearance.
三名因晶状体后纤维增生继发黄斑颞侧移位的患者伴有真正的斜视，并伴有弱视以及与大的正角κ相关的假性斜视。在其中一例中，与眼球震颤中性点相关的头部转动也是一个突出问题。通过光反射试验和棱镜遮盖试验测量眼位偏斜，特别注意获得足够的外观对齐。在注视眼前放置大量棱镜会导致视力下降，而通过手术使眼睛处于平行位置可能看起来并不直。因此，手术可导致眼球平行对齐，而可能需要棱镜疗法来使瞳孔光反射居中并提供令人满意的外观。
