用优先注视技术测量双眼形觉剥夺婴幼儿的视力。在研究的10名儿童中，有5名患有先天性白内障，5名患有未矫正的高度屈光不正。在2个月之前接受白内障手术的婴儿显示出正常的早期视力发育。治疗前延迟4至6个月导致视力下降，但随后恢复。高度远视或散光的婴儿在出生后的第一年进行光学矫正测试时没有显示出视力缺陷。1例在出生后第3年发现早期视神经性弱视。缺陷不是永久性的，经过一段时间的光学矫正，视力恢复到正常水平。
Visual acuity was measured with a preferential looking technique in infants and toddlers with binocular form deprivation. Of the 10 children in the study, there were 5 with congenital cataracts and 5 with uncorrected high refractive errors. Infants with cataract surgery before 2 months of age showed normal early development of visual acuity. A 4 to 6 month delay before treatment resulted in reduced acuity but recovery subsequently occurred. Infants with high hyperopia or astigmatism showed no acuity deficits in the first year of life when tested with optical correction. One case of early meridional amblyopia was detected in the third year of life. The deficit was not permanent and, after a period of optical correction, there was recovery of visual acuity to normal levels.
