Nine cases of esotropia occurring in deprivation amblyopia, where exotropia rather than esotropia is usually found, showed a refractive error of hypermetropia. This fact suggested that an accommodative factor is largely responsible for the development of esotropia. A- or V-pattern strabismus was encountered in a higher incidence in deprivation amblyopia than in ordinary strabismus. Pattern-reversal VEP showed more prominent abnormality than flash VEP did. Studies of the sensitive period of the visual system revealed that the sensitivity is likely to be low for a month or two after birth and increases with a peak around the 18th month of age, decreasing thereafter with a waning slope to the end of the 8th year of life.
在通常会出现外斜视而非内斜视的剥夺性弱视中，有9例出现了内斜视，这些病例均表现为远视屈光不正。这一事实表明，调节因素在很大程度上导致了内斜视的发生。剥夺性弱视中A-或V-型斜视的发生率高于普通斜视。图形翻转视觉诱发电位（Pattern-reversal VEP）比闪光视觉诱发电位（flash VEP）显示出更明显的异常。对视觉系统敏感期的研究表明，出生后一两个月内敏感度可能较低，在18个月左右达到峰值，此后逐渐下降，到8岁时降至最低。
